Each Castle of Crystals game features 15 symbols on a 5x3 grid.

Here’s how the game works.

1. During each game, 15 symbols will be revealed in the play area. Reveal three or more matching symbols that share a side to automatically remove that cluster of symbols from the board and win a prize per the Prize Chart. For each symbol removed, a new symbol will drop down from above. A WILD symbol can substitute for any symbol except the FREE PLAYS symbol and the SUPREME JACKPOTS symbol. If the Ice Queen throws her crystal orb on the board when a WILD symbol is part of a winning cluster, a Multiplier will be revealed. Any winning cluster's prize is multiplied by the Multiplier amount revealed for that game.
2. Reveal three FREE PLAYS symbols to unlock 10 free plays. The free plays follow the same game mechanic as the main game. Free plays will play automatically.
3. Reveal three SUPREME JACKPOTS symbols to activate the Supreme Jackpots Bonus Game. The Bonus Game has five rounds. In each round, a new set of symbols drops onto the game board, and the number of rounds is reduced by one. Symbols that enter the board can either be nonwinning BLUE J symbols or GOLDEN J symbols. If a GOLDEN J symbol is revealed, it will be removed and will fill the Prize Meter. For each symbol removed, a new symbol will drop down from above. The Bonus Game ends after the fifth round. Once the Bonus Game ends, the player is awarded the prize reached on the Prize Meter. The player is awarded only the largest prize reached on the Prize Meter. Any Multipliers on the main game board are not applied to any wins in the Supreme Jackpots Bonus Game.
