Sudoblock

How to play

• Drag a block from the tray onto the 9x9 board. On a phone the block floats just above your finger so you can see where it lands.
• Fill a whole row, column or 3x3 box and it clears.
• Blocks cannot rotate. What you see is what you get.
• When none of the blocks in your tray fit anywhere, the game is over.

Scoring

• 1 point for every square you place.
• 18 for one clear, 54 for two at once, 108 for three, and it keeps climbing.
• Clear on back-to-back moves for a combo bonus of 20 per combo step.
• Wipe the whole board clean for a 300 point bonus.
