Square Sort

Slide, swap, and sort colored squares into tidy groups before the board locks up — Square Sort turns a basic grid into a surprisingly tense puzzle.

Square Sort doesn't look like much at first: a flat grid, a handful of colored squares, and a one-line instruction that just says 'slide to play.' Then you're ten levels in, realizing you should have planned that third move about four moves earlier. The core loop is straightforward — drag a square into an empty adjacent space, or swap it with a neighbor, and watch matching colors bunch together. The catch is that every slide shifts the entire row or column, so moving one piece can wreck a whole cluster you'd already set up. That's where the 'aha' comes: you'll find yourself reverse-engineering moves, treating it less like a match game and more like a mini chess puzzle. I kept trying to brute-force a stage where three red squares were trapped behind a wall of blues, and it took me a solid five minutes to realize I could push an entire column down instead of trying to wiggle individual pieces. That's the kind of quiet satisfaction Square Sort trades in. Visually it's clean — flat shapes, bold colors, no clutter — and that minimalism helps because the logic is the star. The difficulty ramps gently: early boards feel like warm-ups, then suddenly you're juggling four colors and trying to remember which way a row slides when you release it. If you're someone who likes puzzles where a single wrong move unravels everything, Square Sort will get its hooks in.

Slide to play

Before your first slide, study which colors are trapped and which have open neighbors — plan two moves ahead. Sliding a full row or column shifts everything, so use empty edge spaces as temporary parking spots. If you're stuck, try working backwards: think about where the final group should end, then trace the moves that get it there. Don't chase one square all over the board — move the surrounding squares to bring the target to you. Early levels are for learning the slide physics; don't rush them just because they look easy. When you clear a color, don't relax: the remaining squares often lock into a tougher layout.
