The provider specification describes the game. 1xBet account configuration may differ by region, so check the game inside your account before play.
Drum Metres and Hold & Win Bonus
Filling Drum Metres with their matching Diamond bonus symbols activates the Hold & Win Bonus, with a chance to land Diamonds with Mini, Minor, Major or Grand jackpots. Filling the entire bonus board may also award the Grand Jackpot prize. Players can activate additional bonus features mid-round by scoring Diamonds tied to inactive Metres.
Bonus Boosters: Collect and Multi
Each activated Drum unlocks a special bonus feature. Collect gathers all symbol values. Multi applies multipliers to random empty cells, adding a +1 boost when a multiplier strikes the same cell. There is also a chance to activate all three features together.
Extra Feature
Extra expands the grid with two extra rows and can randomly duplicate a symbol from one extra row to the other. Filling the expanded grid may award the Extra Grand Jackpot.
Master Drum
The new Master Drum can thunder to life at any time during respins, releasing up to three bonus symbols, all of which have the potential to hold jackpot values from Mini to Grand. In the base game, the Master Drum can also trigger any of the features, or even all three at once.
Super Bonus
The Super Bonus unlocks all three features, boosts symbol values and ensures the Master Drum strikes at least once per round, releasing only jackpot symbols. This mode is available in select markets via the Buy Bonus engine.
