Developer 15 Coins Grand Gold Edition is a high-volatility slot from Wazdan in the Coins series, released in 2024. The game uses 15 reels and has an RTP of 96.18%, with a maximum win of 2,000x the bet and a treasure-themed design. The title combines Cash Infinity™, Hold the Jackpot™, Chance Level™ and Sticky to Infinity™ mechanics, with a focus on repeated bonus triggers and prize collection.
Players can use the demo version to play for free and practice before playing for real money. The slot also includes a unique Gamble Feature, offering a 50/50 chance to double a win up to seven times after a winning spin. Additional options include a Buy Feature for direct access to bonus play and Ultra Fast Mode, which speeds up the pace without changing the game’s RTP or core algorithms.
According to the game details, volatility levels can be adjusted, giving players more control over the balance between smaller frequent wins and larger but less common payouts. The Coins series was also nominated in two categories at the CasinoBeats Game Developer Awards 2024: Game Mechanic of the Year and Game Feature of the Year.
