Mystery Box

Mystery Box is a scatter-pays slot from Golden Hero set in a witch's lair, with crystals, cups, spell books and scrolls on a 4x4 grid. Symbols pay wherever they land, from three of a kind up to a full board of 16, so a single crystal-heavy spin can pay up to 1000x the bet.

Five treasure chest symbols open the bonus: pick one of four chests to reveal a multiplier between 10x and 1000x, then play the bonus respins. A 96.43 % RTP, medium volatility and stakes from 0.2 € to 200 € make it a feature-led option with a big ceiling: the maximum win is 1454150 €.

Wins count anywhere on the 4x4 grid, starting at three matching symbols. Crystals, cups, books and scrolls pay from 0.5x up to 1000x the bet for 16 crystals. Keys, hourglasses, compasses, potions and ink pay from 0.25x up to 700x the bet.

• Bonus symbol: a treasure chest that can land anywhere; five of them trigger the bonus.
• Chest pick: before the respins start, choose one of four chests to reveal a multiplier from 10x to 1000x; the prize is the bet multiplied by that value.
• Bonus respins follow the pick.
• Autoplay for automatic spins.
