Features Spirit Sisters is a dice-based casino slot by Air Dice built around a 4x3 grid with five paylines. The game uses standard dice symbols alongside bonus symbols, with a medium volatility profile, 96.25% RTP and a maximum win of 5,000x the stake. Bets range from €0.25 to €50.00, and the rules state that a single round must reach at least 100 points to qualify for a win.
A key feature is the Spirit Blast Bonus, triggered by three bonus symbols on a reel. This awards five extra spins and can lead to bonus cash jackpots, extra points, or a Mystery/Progressive Jackpot. During the feature, each prize can be accepted or declined, while the final result is taken automatically if all five spins are used.
A demo version is available, allowing players to play for free and practice before playing for real money. The game centres on historic female warriors and uses a straightforward reel layout designed for players looking for a slot with bonus rounds, jackpot potential and dice-based mechanics.
