Only 1 color per line

Grids, colors, and one stubborn rule — Only 1 Color Per Line turns a deceptively clean concept into a surprisingly absorbing puzzle experience. No color can repeat along a row, which sounds trivial until the grid starts filling up and your options quietly collapse.

The satisfaction here comes from constraint. Fewer choices, not more, is what makes each decision meaningful. You're not decorating — you're untangling a logic problem dressed up in color, and the moment a solution clicks into place feels genuinely earned.

Larger grids introduce real tension, where a single misplaced color early on can quietly poison everything downstream. There's no timer pushing you, just the puzzle waiting to be solved on its own terms.
