Wood Blocks

Fill a 10x10 board with wooden shapes and no way to rotate them - that's the entire challenge, in the style most people know from 1010 or Block Blast. Clear a full row or column and it disappears, but leave gaps in the wrong spots and you'll eventually get handed a shape that doesn't fit anywhere. It's slow and low-pressure, with no timer pushing you, which makes it a solid game to play while half-watching something else.
