Crystal Fairy is a timed, match-3 puzzle game set in a world that features many different types of crystals growing in caves and aboveground. Across 25 levels, the player helps the Crystal Fairy grow magical creatures by collecting animal cards on boards filled with colorful jewels. They also try to earn an extremely high score.
The player can only provide this help via match-3 swap gameplay. They swap two non-matching jewels to create a horizontal or vertical line of at least three matching ones with a single move. Every swap helps them slide pieces of an animal card, similar to puzzle pieces, down columns to the end of the board. The game then moves the pieces to an upper-left panel to reform the card.
They must complete every task before the timer in the lower-left area counts down to zero. The player can also keep track of their score in this same area.
Crystal Fairy has power play opportunities. When the player removes the same color of jewels twice in a non-disrupted streak, the game activates helpful powers using charged crystals that appear in the upper-right area. Green crystals remove three jewels from the board at random, purple crystals remove five in a plus shape, yellow crystals add extra time, blue crystals remove one jewel below a card piece, and red crystals remove nine.�
