Place 1×2 and 1×3 blocks so every number matches how far its block can slide.
Controls
Drag across two or three cells in a row or column to place a block. Tap a block to remove it. Every number must be covered by exactly one block, and that block must be able to slide into exactly the shown number of empty cells along its long axis. Blocks cannot overlap.
