About Colour the blocks
Sharpen your mind with a connect-the-block-style one-line brain training puzzle game. A simple but addictive one-line puzzle game that’s completely free to play. Your brain becomes more active the more you play. During your commute, before you sleep… enjoy downtime with brain training. The rules are extremely simple. Just fill in all of the blocks using only one line.
It's a straightforward puzzle game that gets out of your way and lets you play. Whether you want a quick five-minute break or a longer session, it runs smoothly on just about any device.
If you want to do well, keep this in mind: Slow down on the first level — the early stages teach mechanics you will need at the end. Work from the corners and edges inward — they usually have the fewest possible solutions.
Colour the blocks is part of the hand-checked Glaze Games puzzle collection. Press Play to start instantly — no account, no download, just the game.
