Easy to read, hard to master
No lengthy tutorial required — the first level is immediately playable. As you progress, the board gets more crowded and block shapes get less regular, testing your sense of space and sequencing.
Free · Ad-free puzzle
Inside the edges, color calls the shots.
Boundary Color Edge Blocks is a compact spatial-reasoning puzzle game. Colored blocks line a tightly packed board, each one marked with a directional arrow. Your job is to find blocks that share both a color and an arrow direction, then slide them together to clear them. The rule is simple — but every move shifts the whole board, and one wrong slide can cost you several extra steps to fix.
The game is completely free, with no ads interrupting your thinking. Play it right now in your browser, or grab it on Google Play and pick up where you left off on your phone.
