FrostMatch

Swap adjacent gems on an 8×8 board to match three or more of the same color and score points; each cleared match has a 20% chance to spawn a snowflake-marked frost block that stays in place (max 5 at once, oldest unfreezes when exceeded); when a row is cleared, frost blocks in that row are removed for +2 bonus each—you can Reset the board or Exit to the home screen, with high scores saved locally via Room.
