Click on a gem to highlight it, then move to swap it with an adjacent gem. Match 5 or more identical gems in a line to clear them from the board. Make a column of 4 gems to produce a power-up gem that removes an entire row when used. Think your moves carefully to complete the level's target within the allotted number of moves. Watch out for obstacles like frozen gems that require specific conditions to release. Progress through various levels, each with different challenges and objectives.
