Puzzlix: Shape Fitting Puzzle

Puzzlix: Shape Fitting Puzzle gives you a set of irregular shapes and one outlined grid, and the whole challenge is rotating and slotting every piece in so nothing overlaps and no gap is left uncovered. Unlike a standard jigsaw where each piece has one obvious home, these irregular shapes can often fit into more than one spot at first glance, so working out the actual solution means reasoning about which combination of placements leaves no wasted space anywhere on the grid — a genuine spatial-logic problem, not just visual matching. Starting from the grid's corners and edges, where fewer shapes can possibly fit, tends to narrow the puzzle down faster than guessing at the open middle first. It's a strong pick if you enjoy tangram-style shape puzzles that reward planning ahead over trial and error. Free to play directly in the browser, no download needed to start fitting pieces.
