The game begins with a full screen of randomly placed gems of 7 colors. Players choose 2 adjacent gems (horizontally or vertically adjacent) to switch places on the game board. If the switched gems create a row of 3 or more identical gems, the gems switch, then disappear, and the player earns points! Then new gems appear on the top of the game board, and the player continues to make matches until the 5:00 timer runs out or until no further matches are possible.

Players earn additional points for gem rows of 4 or more, and can earn additional points when multiple matches are made on a single play. After 30 seconds of game play in which a player does not make a switch selection, the game provides a hint, flashing two interchangeable gems.
