🧩 WHAT ARE PENTOMINOES?

Pentominoes are shapes made of 5 connected squares — like Tetris pieces but with more variety. There are 12 unique pentomino shapes, each named with a letter (F, I, L, N, P, T, U, V, W, X, Y, Z). Players share the same set and take turns placing them.

🏆 STRATEGY

The goal isn't to fill the most cells — it's to block your opponent from placing any more pieces. Create awkward gaps they can't fill. Save flexible pieces for later. Force them into corners while keeping your options open. Every game plays differently.

DEADBLOCK is built by an independent developer and is completely free. No accounts required to start playing — just open the app and go.
