Features Mystery Arena by GAMING1 is a dice game built around a 3x3 grid and five paylines, with an RTP of 96.00%. The game includes a lottery-style bonus round where prizes are linked to two mythical creatures, Medusa and Griffon. Players can view the demo version to play for free and practice before playing for real money.
During the bonus feature, the game presents five prize offers that may be accepted or refused. Possible rewards include credits, points and additional Mystery games. Two Mystery Jackpots are contested in the Medusa and Griffon duel, with special outcomes tied to stopping the Gauntlet bonus or illuminating the shield.
Betting starts at €0.25 and reaches €20.00. Mystery Arena is designed for desktop play, supports tournament play, and does not include free rounds. Its structure and bonus rules make the game focus on prize selection rather than a traditional free-spin format.
