Classic Slots
Traditional three-reel slots with simple paylines and straightforward gameplay. NetEnt and Microgaming are well known for their classic collections of this type.
Video Slots
Modern five-reel slots featuring advanced graphics, bonus rounds and free spins. Gates of Olympus by Pragmatic Play is a popular example of this type.
Jackpot Slots
A portion of every bet goes into the jackpot pool, which one lucky player wins. Microgaming is a pioneer in this type of slot.
Megaways Slots
The size of the reels changes with every spin, creating thousands of ways to win. Sweet Bonanza by Pragmatic Play uses this mechanic.
Cascading Reels
Winning symbols are removed from the board and new symbols fall into place, creating the chance to win multiple times in a single spin.
Cluster Pays
Instead of paylines, you match clusters of symbols side by side or above and below each other. Several popular games from NetEnt and PG Soft use this format.
