Our slots dictionary covers a wide variety of slot machine terms related to online and mobile slots alphabetically ordered.

Instead the symbols will pay out from left to right, if the symbols are anywhere on the reels, in order. So to get three of a kind, you’ll need to get a symbol on reel 1, 2 and 3, anywhere you like. A good example of a 243 ways to win slot is Voila!

3D Video Slots

Typically created by BetSoft gaming these 3D slots are usually graphically heavy with animations. The graphics will give an enhanced depth and the symbols within the 3D slot machines will come out of the screen upon hitting a winning payline.

Active Payline

Depending on the slot it could have 1 or 99 paylines. Active paylines are simply where the symbols need to line up in order for the slot machine to pay a prize. You can choose how many paylines you wish to bet on. A payline becomes active if you are betting on it when you spin. Winning combinations only occur on active paylines.

Balance

The balance is how much money you have left in your casino account to place bets with. You will often find a real money casino balance which states how much withdrawable real money you can play with and a bonus money casino balance which shows how much bonus money is available to bet with.

Bet Max

The maximum bet (in cash or coins) for the maximum amount of active paylines that a player can bet on a slot machine.

Bet Min

The minimum bet (in cash or coins) for the maximum amount of active paylines that a player can bet on a slot machine.

Big Hit or Win

If this flashed on your screen, then well done! You’ve hit the correct reels and symbols that make up a large win or jackpot combination on a particular slot.

Bonus Feature

These are extra features within the game outside of the standard winning payline combinations. They can refer to mini bonus games like click me or pick me features seen in After Night Falls, or Expanding Wilds like in Super Safari and Free Spins such as the ones found in Jack hammer.

Cascasding / Collapsing Reels

Often referred to as tumbling or exploding reels, this is when the winning symbols ‘explode’ and disappear from the screen. The symbols on top ‘collapse’ down and more symbols ‘tumble’ or ‘cascade’ from above to replace the symbols that disappeared. This can lead to a chain reaction of multiple wins.

Megaways slots are a good example of slots with changing ways to win.

For example if a slot has 96% RTP then for every £1 bet it will return 96p to the players over its entire lifetime. It doesn’t distribute these amount equally, hence why sometimes you win and sometime you lose – sometimes you get someone else’s 96p back, sometimes someone else gets yours.

Variance / Volatility

Two terms meaning the same thing. This basically describes the risk of the slot machine. A low volatility mobile slot will be low risk, paying out often, but little. Your balance is likely to be kept continually topped up. These slot machines are great for players who want their budgets to last and are seeking entertainment. High volatility slots, are high risk. They do not pay often, but when they do… it can be life-changing amounts. These slot machines are far better at chasing the big jackpot win and have a healthy bank balance and the patience to wait for the machine to pay out.

Video Slots

Typically containing 5 reels, these video slots contain animations when winning symbols are found on an active payline. An example would be Foxin’ Wins, where Fox cubs run across the screen turning random symbols wild.

Ways to Win

Ways to Win is the term given to online slot games which usually pay from left to right, but instead of paying on a specific payline, pay for finding the same symbols on adjacent reels, typically 3 or more.

Wild Symbol

This symbol is the joker in the pack. It can substitute the other symbols in the paytable, creating multiple wins on active paylines. These can, and often, come with a multiplier and rarely substitute for scatters or bonus symbols.
