Module 5: Desktop Edition

A hologram-blue pentomino board you solve, reshape, and reskin. Module 5: Desktop Edition takes the same 12-module system as the Android game and turns it into a browser-native puzzle solver — no gravity, no tower, just the board.

Two ways to play

• Classic — fill a 6×10 board with all 12 pentominoes. There are 2,339 unique solutions, and the game tracks which ones you've already found.
• Shapes — 20 levels, each with a target silhouette to reproduce, from trivial to brutal.

Design your own

Draw any silhouette cell by cell in the built-in editor. Before you can save it, the game's own solver checks that it's actually solvable — no publishing an impossible board. Every challenge you make gets a short code you can share, so a friend can import and play the exact shape you built.

Six ways to see the board

Terminal cyan, green-phosphor ASCII, architectural blueprint, 80s synthwave, and a hand-drawn ink-on-paper sketch (light and dark) — swap the whole visual identity of the game from Settings, any time, mid-game included.

Controls

Full mouse and touch support, plus complete rebindable keyboard shortcuts if you'd rather never touch the mouse.

Runs entirely in your browser, works offline once loaded, no install, no account, no ads.
