Push your tile into a column and the bottom one pops out into your hand — that swap is the whole engine of Color Columns, and it's a genuinely fresh spin on the sorting puzzle. The goal is to work every column down to a single color and free the trapped rainbow tile, all before your move counter runs dry.

What separates this from a plain color-sort is how the pressure builds. Bombs, hidden tiles and boosters keep muddying your plans, so the neat little sequence you mapped out three moves ago rarely survives contact. Boosters give you an out — undo a slip, swap tiles, or auto-sort a stubborn column — but they're a resource, not a crutch, and leaning on them too early tends to bite.

The clever part is the scoring. An AI solver rates each clear against its own optimal solution, so your number reflects how close you came to a flawless run, and it feeds a leaderboard worth climbing. Tap or click a column to push (keys 1-7 work too), which makes it comfortable on phone or desktop. It's a free browser puzzle that rewards planning over speed — and if that's your lane, there are more puzzle games nearby.
