Online Slots Overview from KatieWager.com[show/hide]
Playing Slots of All Types
Every person is unique in their own way and has differences in preferences. Luckily, slots vary so much that there is a game for everyone. Whether that be an American classic, a British slot machine (fruit machines), or the Australian slots machine (pokies), something will appeal to the individual. Each of these slot machines differs in many ways such as payout percentages, themes, slot bonus, number of reels, slot strategy, jackpot amount and mix/max bet, devices: mobile slots or PC slots. Let’s look at casino slots more in-depth!
-
Interface
- 3-reel machine – it’s a slot machine where the interface is simple and intuitive with a clear design and traditional slot icons: cherry, BAR, and “7” plus bonus symbols.
- Video slots – 5 or more reels with fantastic slot icons and animated introductions.
- 3D slots – 3D graphics on these slot machines really pop for the user with custom animations and cool effects.
- MegaSpin slots – as Double Magic or Fantastic 7s, allow the player to get into the action in casino slot games on multiple machines at once!
-
Themes of slot machines
Themes are a core part of the online slot games experience. Each different slot machine games will take you on a wild ride through a limitless number of themed games. These could include different game selection like horror, adventure, movies, fantasy, sports, etc. For example, the slot game Halloween Fortune features black cats, witches, skulls, and vile elixirs.
For the athletically inclined, Football Star features balls, players, and jerseys set to the grassy field background. If comics are your thing, the slot game of Superman: The Movie Slot brings you into the action with kryptonite, secret identities, costumes and heat vision.
-
Betting Size
There’s a betting size for everyone. There are players who want to wager the minimum, and some slots wagering requirement of just one penny. Known as penny slots, these penny slot machines are popular with those who love the thrill but aren’t willing to put a lot of cash on the line.
High-roller slots, on the other hand, are made for those who enjoy risk in slots games. Some bets are a minimum of $1, but single bets for each spin can reach into the hundreds of dollars. Pay attention to the high wagering conditions applied to these slots titles.
-
Paylines in slot games
In real money slot games, paylines describe how a player can win on any given spin. Using a traditional slot games, there is a single line and therefore you must match each symbol three times to score. However, multiline slot machines are all the rage in today’s casino games community that can implement different slot machine strategy.
With several reels and more lines in slot games, there are dozens of ways and slot machine tips to win with coordinating symbols. If that wasn’t enough, Microgaming and Netent have released slot games with as many as 1024 paylines. These days, you might even win in your favorite slots games without even realizing it, so the excitement is always churning!
Online Slots Bonuses
The initial bonus new players receive is in the trial slot casinos games which don’t use real money. Instead, they use demo credits so that players can effectively try slots strategy and get the first experience in slot casinos before they buy. Once the trial slots become tiresome, there are some great bonuses out there in the real money world.
While some gaming top operators offer their own casino bonuses unique to slots casinos games, software providers may even build bonuses inside real money games to incentivize players to keep spinning the reels on favorite slot casino. Let’s examine these slots’ bonuses closely and explain how they can be taken advantage of.
Inside Slot Game Bonuses with Bonus Features
Wild Symbol – The wild symbol is a unique icon in each slot game, and usually have “WILD” printed on them. They act as a space which can represent anything you need it to. However, check bonus terms by each online casino cause bonus terms for each bonus symbol are variable. Although, Wilds are very valuable. For example, in Jack and the Beanstalk casino slot games, the wild appears as a giant “W” vine. Some online slots casino games have expanding wild tiles, which is an entire vertical or horizontal reel that is wild, giving players huge opportunities like getting bonus cash or bonus rounds.
Scatter Icon – The scatter icon gives players free spins or bonuses offer from certain game is provided to players when a certain number of these scatter icons appears on the screen. For example, in the game 1Can 2Can online slot, if 3 scatter symbols appear, 10 free spins as bonus wins are gained.
Free Spins – Free bonus spins sound exactly like what they are—free tries to win! Usually, the best online casino will give out free bonus spins as signup bonuses or for loyalty points. Free bonus spins may also be gained through in-game actions such as getting scatter icons or wild icons.
Gamble Feature – The gamble feature gives players an extra chance to risk it all. Typically, if a player wins in an online slot, a gamble feature will be offered. This offer will have the player guess a card suit, a dice roll, or a high/low number. If guessed correctly, the player can double or quadruple their money. If guess incorrectly, then it’s all lost. For example, Prosperity Palace online slot game allows players to choose red or black to double winnings or guess a suit to quadruple.
Multipliers – Multipliers exponentially increase winnings in online slots games. Usually, there will be certain reels that have multipliers, or a multiplier might build up as the effect of a bonus. In Microgaming’s Mega Money Multiplier, there are wild icons that have multipliers up to 5x.
Bonus Rounds – Bonus games or bonus rounds are special scenarios which are usually triggered by scatter icons. These bonus rounds have players complete special mini-games that cumulate into big winnings. In the casino game Avalon II, for instance, players are given a bonus slots games when they have 3 holy grails on bonus spins. The casino bonus game involves getting to the Isle of Avalon and unlocking a huge multiplier for the initial bet that can reach into the thousands.
Cascade Reels – Cascade reels are different because any winning symbols on the reels are paid out and simultaneously replaced with new symbols. This means that it’s possible to win extra on the newly appeared icons to get bonus winnings. In casino game Gonzo’s Quest, the falling blocks smash when they are part of a winning combination. The new blocks fall into place and generate new chances to score.
Casinos suggest promotions or bonus offers all the time. Whether you are a brand-new player or a seasoned veteran, expect to have some online casino bonuses aimed at you. These bonuses range from free bonus spins, to deposit rewards, to no deposit offers. Check out your casino of choice’s website home page, the promotion section, or even your email to find these great bonus offers.
Free Spins
When thinking of casino slot bonuses, you undoubtedly think of free bonus spins first. These are free chances to win bonus money, but they change depending on the casino slot game you choose. Most will provide you with a small sum of 10 or 15 free bonus spins. However, some may give the user hundreds, depending on the circumstances and kind of slot bonus. Of course, wagering requirements do apply, typically on larger spin amounts, so spin wisely!
No Deposit Reward
No deposit rewards are what they sound like—free cash with no deposit balance! However, there are typically wagering requirements and withdrawal limits. These bonus offers usually are in the $10-$50 range for a newbie and up to $1,000 for a high roller. And rollover depends on bonus size you claim. As an example, promo of $500 plus 99 free bonus spins require to play through more than 75 times
Match Bonus to 1st Deposit
This is deposit bonus that has great potential. Depending on your initial deposit on your deposit amount and with wagering requirements, the casino will match anywhere from 100%-500% of the amount. Additionally, the establishment may offer free bonus spins as a bonus. However, don’t be surprised if there is a $100+ minimum deposit balance or a 50x+ wagering requirements.
Composite Match
This is just like the first deposit bonus, but it spread out between your first few deposits. For example, the match may be 200% on the first payment on the deposit balance, with 150% on the next, 100% on the subsequent deposit and so forth.
Free Hour
Free spin hours are rare, but when they come along there is no reason to not take advantage of them. The casino will set aside one hour on slots for you to rack up as much as in bonus spins as possible. Your winnings are subject, typically, to hefty wagering requirements.
Special Game Bonus
These deposit bonuses rely on a casino website advertising a specific game or game variety. The business may reward players greatly for participating in a game of the casino’s choosing. This is typically a new title launched by the developer to promote it.
Returning Program
The returning program deposit bonus offer is given when a player ceases to play at the casino for a long period. To entice the user into playing again, the casino will offer a deposit bonus, free spins with different bonus wagering conditions. This program is great for players coming back to the slots games.
Seasonal Promos of Best Slot Sites
Seasonal promotions can happen weekly or monthly but usually, occur on holidays such as Christmas and Easter. This bonus amount have great value and can give players free spins, bonus rounds or match bonuses and another type of the bonus cash offer as a birthday present.
Loyalty Points
Casinos reward players for being long-term members. The more you play on a website, the more points you receive on your bonus balance. You can cash in these points for tournament tickets, bonus rounds and free spins, or other special offers. Some casinos even use the VIP bonus points as cash to purchase certain products from their real money gambling sites.
Regardless of whether you choose to take special casino promotions or not, it is always preferable to read the fine print at all slot sites you play. Pay close attention to any stipulations regarding payment regulations. Always know what the minimum deposit rates and maximum withdrawal rates of the banking options are before diving in. Additionally, if it is necessary, view the rules on payment methods so you don’t get caught unaware when you try to add one or get stuck paying fees. Actually to see how it works, I recommend to check streams and videos showing payment process with all details.
With payment methods, credit/debit cards are the most convenient for the average user because they require no special set up and most people have one already. The downside of these banking options is that fees and processing times are generally high. E-wallets are in the same boat, but many casinos refuse to accept them. However, the best method is often Bitcoin or another cryptocurrency as the transaction times are low and fees are usually very low or nonexistent.
Best Slot Software Developers

If Microgaming had a postcard, it would certainly have a unique slot game on it. This software developer company has the largest selection and variety of casino games available with a new slots game being introduced every few weeks. Their gaming titles boast greater than 40 progressive jackpot slots and in 2009 made one man a millionaire through a tournament. They are a quickly growing business and in 2014 created the first virtual slot game for Samsung smartwatch. They also are partnered with Derivco, the foremost leader in the Augmented Reality developer.
When it comes to slots game, Microgaming doesn’t mess around and I repeat this for several times on my streams. Consider the Forbidden Throne online casino slot game, which rakes in players from a 23 million viewer pool from the popular Game of Thrones series. Or, consider the progressive jackpot Mega Money Moolah which had paid out millions in one sitting. With Microgaming, there’s quality gaming experience for everyone!
Slot Reviews of Immortal Romance
This gothic slot casino game features 5 reels with over 200 methods to winning big. With a vampire theme, the wild card is an Immortal Romance logo and there’s even a bonus game triggered by scatters called the Chamber of Spins. If you’re a Twilight fan, this is your go-to!
Slot Reviews of Terminator 2™

Slot Reviews of The Invisible Man™
Make the wilds collide in this re-spinning, free-spinning offering by NetEnt with a bonus game that pits the police and the invisible man against each other.
Slot Reviews of Gonzo’s Quest™
The key point to Gonzo’s Quest is the stacking element, wherein symbols that win are destroyed and create new symbols for a chain effect of constant winning.

Playtech is unique in that they have contracts with major comic book companies such as Warner Bros. and DC. This means they can create the best quality superhero jackpot slots games on the market. These slot developers’ leader specializes in all forms of gambling technology but are most proficient in 3D slots and mobile technology for their customers.

Great bonus games slots and a balance between variance and volatility slots makes Yggdrasil games popular among slots players. The formula of Yggdrasil combines the previous factors with wilds, progressive jackpots and free spins and bonus spins rounds to entice players. Games: Popular volatility slot games include themed games such as Orient Express, Easter Island, and Jungle Books.
Online Slots from Technical Side
You may not believe videoslots are fair. You may think that jackpots are rigged. However, all licensed machines have a Random Number Generator (RNG) calculator that ensures all slot games are completely fair and random. The house wins with a slight edge in all instances, but below we’ll discuss the concepts to get a better picture.
RNG – There are two main types of RNG. The first is called Pseudo RNG, which is not entirely random as it uses a seed value to calculate the outcome. Genuine RNG is an algorithm that generates totally random outcomes from scratch. These methods of running video slot machines are verified and provided with a gambling license by institutions dedicated to fairness in gaming including eCogra, The Gambling Commission, UKGC (UK Gambling Commission), and MeGa.
House edge – is the percent chance the operator website has to win over the player. These percentages are usually between 1% and 10%. These edges are manipulated by the casino sites software, as they can tinker with the software to change how often a symbol appears or how often a jackpot is struck, therefore altering the house edge.
RTP – stands for Return to Player (slots payout percentage). Payout percentage is a part of money that the slots player is expected to get back over time when playing. For example, slot payouts (RTP) of a 96% will give back the player 96% of all money over infinite uses. This is calculated based on the win ration of all possible combinations and the frequency of each combination coming up.
Dedicated Slot Tournaments
Online slots aren’t just for singular use. There are tournaments of different kinds which are discussed below. Before entering, I suggest noting the following: 1) Ensure the start and end stamps so you know you are available during those times; 2) Determine if the entrance fee is worth the prize pool; 3) Examine closely the casino website so you have faith in the platform.
Free Entrance
The tournaments are completely free. However, the prize pools are typically extremely low, perhaps $100 spread over the top performers. These are great for newcomers as it allows them to gain slots experience.
Sit and Go
If you don’t want to wait around, Sit and Go’s are the best. You pay a static fee and play with a set amount of players with a guaranteed prize pool. These tournaments are short, sweet and to the point.
Pay to Play
These tournaments have incredibly large prize pools but are home to tons of players, so the competition is fierce. Also, the buy-ins are usually steep, so you had better perform well!
All Day Long
Day-long tournaments can run you ragged, but the rewards are great if you can last. Sometimes entering in the early morning and not getting done until late in the evening, the leaderboard will show top players and prizes at the end of the day.
Ongoing
Ongoing tournaments last multiple days or weeks. This means that planning and strategy are key, but the most important aspect is being able to play for so long. You’d better clear out your schedule if you want to participate in one of these!
Jackpot Types and Biggest Winners Ever
Flat Tops
Flat Top machines are those with a fixed jackpot rate. These are good because you could wager a single coin and win huge. However, the chances never change and are typically very low.
In-House Progressive
Progressive slots dazzle the masses because the numbers just keep going up. Progressive slots are beneficial because you know that beast must hit sometime, but even though it becomes profitable to play a progressive jackpot, the house always has an edge.
Wide Area Progressive
These are essentially in-house progressives but are linked through multiple casinos. This means that hundreds or thousands of people playing simultaneously are making the jackpot increase. The numbers can be HUGE, but at the same time, the jackpot chance may be staggeringly low.
One day, I know I’ll be a jackpot winner. Although it hasn’t happened to me yet, let me show you how big some have struck it. Online gambling can truly make dreams come true!

My Best Slot Tips for You
Having looked at this review and my stream profile on Twitch, you’re likely cocky about your online slots machines knowledge. You should be! But, I always leave the best for last. Here are some last-minute tips to trying to score big on the slots. These slot machines tips are the general strategies that players uses depending on the budget they have and can spend:
- Up One Step – While risky, the Up One Step method doubles your bet until you win. On a win, you reset back to the minimum. The theory is that if you double the bet each time, you will eventually win, and cover losses. That is until you reach the max bet.
- Ladder – This strategy increases the bet on a win and decreases it on a loss. For example, if you wager 10 coins and win the spin, you bet 11 coins. If you lose, you spend only 9. This lasts until you are betting the maximum. You end the session when you spin the minimum 3 times in a row.
- Umbrella – The strategy here is to vary your bets from large to small to give yourself a shot at winning bigger amounts. The pattern starts low, goes high, and comes back down, forming an umbrella.
My essential advice for you – finish the game once you see an empty bankroll or reach a loss limit!
And some myths that I want to destroy:
“I have a special feeling that I will win today” – NO! Regardless of how strong your intuition is, the process is absolutely stochastic.
“Being positive will help me” – NO! Winnings are not connected to your mood.
“I’m looking for the signs” – NO! Any circumstance like a lucky coin or unexpected job promotion will not change the result.
FAQ
1. Should You Take Casinos Bonuses for Slot Machines?
Yes and No. First, you can take this bonus and win unbelievable sum of money or even a jackpot (in rare occasions ’cause usually, casinos give bonuses for regular slots games and we understand why). However, if you weren’t lucky enough to grab the mount of gold, there is such a condition as wagering requirements that can drasticaly spoil your game session and your mood.
2. What are Wagering Requirements and How to Deal with Them?
WRs are a special condition that applies on almost every casino bonus. Without completing playthrough conditions you’ll hardly have an opportunity to withdraw any of your winnings. Usually, casino sets 30x condition, which means that you have to bet thirty times your bonus amount. For example, your promo is $50, then WRs are $1,500 that must be staked in order to withdraw the winning you get. In case you won $50,000, the sum of $1,500 seems not so scary, doesn’t it?
3. What the Best Conditions to Play Slot Bonuses?
I would recommend you to avoid any bonus offered by casinos, ’cause they all have obstacles and there is always a chance to spend bonus without any return but you’ll still have to meet the WRs or other conditions. But still if you really intend to try your luck with casino bonus, find that one that has the lowest WRs, not exceeding 20x-30x.
4. What Slots are the Most Popular?
All depends on people tastes. Somebody likes traditional one-arm bandits and chose 3-reels slot machines, somebody wants to observe an interesting idea in slot machine or just looking for his/her favourite movie slot. Somebody tends to chose slots with new technologies like AR, VR, etc. The industry niche is the most filled with video slots, that proves the jackpot winning scores. But it’s just a game of luck, don’t forget about it!
5. What Slot Provider are the Most Honorable?
Of course, the most respected and recognizable in gambling industry are RTG, Microgaming, Playtech, Net Entertainment, Quickspin. I would also highlight Wazdan, Play’n Go, ELK, NextGen Gaming, RabCat, Thunderkick.
6. How To Protect Myself from Fraud Playing Slots?
First of all, check the license of the casino app you play (UKGC, eCogra is a must). Then, you need to understand that slots you want to play is a security slots games. Therefore, read online casino reviews with detailed information about slot machine, its RTG value, feedbacks from casino players, reviewers, jackpot games winners (if jackpot giant or small, if it was returned to winner or not). Find a casino review sharing the true info about customer support quality (how fast customer support answers, if all issues they resolve), help to gambling-addicted casino players (if a casino supports players with BeGambleAware org).
7. Which Online Slot Machines Pay the Most?
Finding the best option for yourself has never been easier thanks to slot reviewers as I am, who test all slots for payouts, special features, free spins and bonuses. I have ranked the casinos where there so many unique games to choose from that also have the highest RTP rate. It’s no secret that the highest return to player ensures the biggest winning odds. I’m a huge fan of Goblin’s Cave (99.32% RTP), Dragon Dance (98% RTP), Mega Joker (98.90% RTP), Jurassic Park, Jurassic World (97% RTP) are also shining examples.
