Types of Slot Games — Which One Is Right for You?
The gdb55 slots section features 6 different types of games. Each has its own mechanics — play with a clear understanding of what you are doing.
Classic Slots
Old-school 3-reel slots — simple rules, fruit and bar symbols. Providers like NetEnt create this type of game.
Video Slots
Modern 5-reel games — with themes, animations, and bonus features. Pragmatic Play and PG Soft lead this category.
Jackpot Slots
Progressive jackpot — the prize grows with every bet placed. Microgaming pioneered this category.
Megaways Slots
The reel size changes on every spin, creating thousands of ways to win. An innovation by BTG (Big Time Gaming).
Cascading Reels
Winning symbols disappear and new symbols fall into their place — multiple wins from a single spin are possible. Gates of Olympus by Pragmatic Play is a great example.
Cluster Pays
Wins are formed by matching clusters of symbols instead of paylines — usually played on a larger grid. Sweet Bonanza by Pragmatic Play is a popular example.
