Square Sort Mania is a free online puzzle game where you place layered square blocks onto a grid and match colors to trigger satisfying chain-reaction clears. Each block has four concentric colored layers, and when the outermost color of a placed block matches any adjacent block's outer layer, both blocks pop and disappear. The next inner color then becomes the new outer layer, potentially setting off a cascade of matches across the entire grid.

The real depth comes from planning your placements several moves ahead. A single well-placed block can wipe out huge sections of the grid in one chain reaction, which is exactly the kind of moment this game is built around. The color-layering system means every block you place has multiple possible future states, so you're not just thinking about the current match – you're setting up combos. It's a clever twist on classic match-3 mechanics that keeps each round feeling fresh and unpredictable.

If you enjoy color sorting games, block puzzle games, or match-3 casual games, Square Sort Mania hits all those notes while adding a strategic layer most mobile puzzlers skip. It's a great pick for fans of sorting puzzle games, brain teaser games online, and satisfying chain combo puzzles. Play it free in your browser on any device – no download, no install, just load and play.
