Release Date 
Developer 12 Coins by Wazdan is a treasure-themed slot released in 2023 with a 12-reel layout and no fixed paylines. The game has a listed RTP of 96.13%, high volatility, and a maximum win of 750x the bet. It belongs to the Coins series and combines the Hold the Jackpot bonus round with the Cash Infinity mechanic.
The base game is built around the bonus feature rather than regular line wins. To trigger Hold the Jackpot, players need four bonus symbols on the middle row. The bonus round starts with three re-spins, which reset when new bonus symbols land. Prizes can come from Cash symbols, Cash Infinity symbols, Mini, Minor, and Major jackpots, Collector symbols, and Mystery symbols that convert into other symbols.
A demo version is available for players who want to play for free and practice before playing for real money. The slot also includes a unique gamble feature, adjustable volatility levels, a buy feature for direct access to bonus rounds, and Ultra Fast Mode for quicker spins. Cash Infinity symbols can remain on the reels until the next bonus round, adding a recurring element to the gameplay.
