A real run of the game, recorded with captions and no sound.

Pick a piece and tap the board to place it. Some pieces have one block marked with a white gem.
Fill a whole row or column to clear it. If a gem is in the cleared line you collect it for 25 bonus points.
Gems stay in their block until the line is cleared, so a gem boxed into a half-full corner is worth planning for.
The game ends when none of the pieces left in your hand fit. Your best score is saved on this device.

Put gem blocks where they will end up in a line you can finish soon, not in the middle of an awkward gap.
Two gems in one line are worth the same bonus as two separate clears and save a move.
A gem near the edge is easy to clear early. A gem in the centre needs both its row and its column cleared in some order.
Do not trade a safe board for one gem unless it sets up a bigger clear.
