HOW TO PLAY
Gem Columns
A column of three gems falls down the well. Slide it, flip the order of the three, and let it land. Three or more of one colour in any line vanish, whether across, down or diagonally. The gems above fall, and fresh matches chain for bigger points. If the stack reaches the top, the game ends.
Keys: Left or A and Right or D slide, Up, W or Space flips the order, Down or S falls faster, Enter drops the column at once, R restarts, P pauses, M toggles sound. On a touch screen drag to slide, tap the column to flip it, tap beside it to nudge it, and swipe down to drop it.
Every ten columns is a new level, and each one adds something: faster gems, a shelf that tilts (after a clear, loose gems roll downhill, so you can steer a chain left or right), a fifth colour, stones that break when a clear touches them, suns that clear one whole colour, and a sixth colour. The small dots beside the well count the columns left before the shelf flips. Your best is saved on this device.
