Online Slot Game RTP (Return To Player)

Players who want to try a game of chance must first learn what RTP is. The RTP or Return To Player in slots shows how much a player earns from the bets they make in a slots casino. Every game’s RTP is expressed in percentages. It is also important to note that this is a theoretical number which has been created after a game provider plays millions of test spins. Theoretically games with a higher RTP should give more returns. However, it does not mean you will automatically win. One other important factor to note is that providers give information based on the base RTP but they create versions of the same game with different RTPs and let casino sites choose which version to use. However, the casinos need to state which RTP version they are using on their site.

Types of Online Slot Games

Some players prefer simple games, while others want more advanced games. Virtual slots give casino enthusiasts a whole level of excitement. What makes them exciting is they vary in theme, objective, and prizes. Here is a quick breakdown of the main different types of online slot games that players can enjoy.

Megaways Slots

Created by Big Time Gaming, Megaways is a game mechanic that comes with attractive features. This online slot uses up to 6 reels and has no predetermined paylines. The goal is to match symbols on adjacent reels. Players should expect to see changes in the number of symbols for every spin.

Jackpot Slots

Every player has that ultimate goal: To win that life-changing jackpot! The odds may be long, but you are guaranteed huge winnings on top of standard prizes. Below are two types of jackpot slots.

Progressive Jackpots

Similar to how the lottery works, the pot money in progressive jackpots increases every time no one hits the jackpot. When somebody wins the jackpot, the jackpot amount reverts to its initial amount. This amount grows whenever a qualifying bet is placed, and it stacks up until someone wins.

Daily Jackpot Slots

If you are interested in bagging big wins on a daily basis, grab the opportunity and try out the daily jackpot slots online Ireland. The pot prize value of daily jackpot slots increases every time bettors place a qualifying wager. Remember, these promotional prize pots can be won once every day.

Slingo Games

With Slingo games, players get the best of both worlds — for the game itself is a combination of slots and bingo. Slingo games feature high-quality visuals and captivating sound effects borrowing mechanics both from slot games and from bingo.

Traditional Slot Machines

Traditional slot machines have a lot of the same mechanics as online slot games but the terminology is slightly different. We will go over some of the important terms below and explain what each means.

Multi-coin/Multi-line

These slot machines work similarly to online slot games in that they allow players to choose how many paylines to play on and how many coins to bet on each payline. If you choose to deactivate paylines you will spend less money however your chances of getting a winning combination also decrease. Once you activate multiple paylines your bet per spin will increase but you will have higher chances of getting a winning combination. It is important to note that you are not increasing the win amount, you are just increasing the frequency.

Buy-a-Pays/ Hidden Buy-a-Pays

A Buy-a-Pays slot machine changes the number of winning combinations and symbols based on your stake. This means if the machine has, for example, fruit symbols, bar symbols, and lucky 7 symbols, you would need to bet three coins in order to unlock all three symbols as winning combinations. Unless you are prepared to place max bets on each spin, do not play Buy-a-Pays slot machines. A hidden buy-a-pays machine refers to a slot game in which the bonus feature will only trigger if you place the max bet.

Straight Multiplier

A straight multiplayer is a type of slot machine that allows players to multiply their win amount by the number of coins they bet. For example, if you bet one coin, all paylines and combinations are available but the win amount will be at the base level. If you bet two coins, all the paylines and combinations remain the same, but the win amount is doubled.

Combination Slots

This traditional slot is a combination of the other types. They are also called Hybrid slots. The slot could be a Multi-coin and a Buy-a-Pay, or Hidden Buy-a-Pay and a Straight Multiplayer.

What are Slot Reels?

Slot reels are a major component of slot machines. These are positioned vertically on the grid with different symbols on each reel. After placing a wager, the reels spin. After the spin stops a win is triggered if there is a winning combination on an active payline.

Types of Slot Reels

There are many different types of slot reels especially with the thousands of video slot games available nowadays. Here are some of the most prevalent types of slot reels in online slot games.

Three-Reel Slots

Three-reel slots are most commonly associated with classic slot games. These are usually the simplest type of slot game with a 3x3 grid layout. On the most basic versions of the three-reel slot games only the middle payline is active. However, more contemporary three-reel games play around with this and provide more paylines and other features to make the games more interesting for new players.

Five-Reel Slots

Five-reel slots are currently the most common type of online slot game setup. The grid layout is usually 5x3 and if you take a look at most of the slot reviews on Gambling Zone, you will quickly see that most slot games fall under this category. The most popular games are most often 5-reel slots as well. These slot games also offer a lot more flexibility in terms of how many paylines are available, but the most common configurations are 10 or 20 active paylines.

Seven-Reel Slots

Seven-reel slots add an extra level of complexity to the online slot game and give a lot more winning combinations and game mechanics. Megaways slots are also in this category. The number of paylines and winning combinations increase to the thousands in these games. There are also certain slot games where the number of reels change depending on whether you are playing the base game or one of the bonus games.

Cascade Reel Slots

The final type of slot reel layout which is important to mention is the cascade reel. This also has a number of alternate names such as tumbling reels, or pay anywhere reels. These reels can have any number of grid layouts from a traditional 5x3 layout or a 10x10 layout. What makes these reels different is that when you trigger a winning combination the winning symbols disappear and more symbols fall from above to replace them. This is the cascade or tumble. Once the new symbols fall into place more winning combinations can trigger on the same spin. Pay Anywhere slots function the same way but instead of working with paylines the wins trigger if you have enough symbols clustered next to each other.

Online Slot Game Paylines

Ten examples of different slot paylines

The online slot paylines are lines that determine the winnings based on the combinations. These may appear as different patterns on the reels. You may see combinations on straight, diagonal, and even zigzag lines. You will only trigger a win for the paylines that you have placed a bet on.

Bonus Features in Online Slots

In classic three-reel slot games there were not many different ways to win while playing the game. Nowadays, slot games are full of different features and bonus games. In order to trigger these bonus games and features you need to either get a winning combination, get a certain type of symbol on the reels, or they can trigger randomly. Here are some of the most common bonus games you can find on an online slot.

  • Free Spins: You will get a certain number of spins without having to wager
  • Jackpot: You can win a set amount of money depending on the jackpot amount
  • Gamble: You can play a mini game to increase your winning amount
  • Respin: The reels continue to spin as long as you get wins
  • Bonus Buy: You can spend money to play a bonus game
