About this Slot
Cosmic Doubles features a space, steampunk and sci-fi theme on a 6-reel, 5-row grid with cluster pays mechanics. The game holds an RTP of 96% and high volatility, with a maximum win of 12,500x.
Cosmic Doubles uses cascading reels, which remove winning symbols and allow new symbols to fall into empty positions. Stardust lands on regular symbols during cascades and doubles the global multiplier on wins. This multiplier increases with each cascade, reaching a maximum of x4096. When multiple Stardust symbols land in the same cascade, each triggers a separate doubling.
Golden Planetarium is the scatter symbol and controls entry to bonus features. Three Golden Planetarium scatters trigger the Bonus, awarding 10 free spins with a persistent multiplier starting at x1. Four Golden Planetarium scatters trigger the Super, awarding 10 free spins with a persistent multiplier starting at x8. Five Golden Planetarium scatters trigger the Hidden bonus, awarding 15 free spins with a persistent multiplier starting at x16. The Hidden bonus is not available through the standard buy menu and triggers only naturally or through Mystery.
During free spins, landing three or more Golden Planetarium scatters awards 5 additional spins.
Bonus buy options are available at the following bet multipliers: Bonus at 1x bet, Super Boost at 3x bet, Super at 8x bet, Hyper Boost at 10x bet, and Nova Spin at 16x bet. Nova Spin starts one spin at the specified cost.
