Tangram Puzzle

A calm logic classic that feels great with touch or mouse. Each level presents a silhouette—swan, house, sailboat—and seven wooden pieces you rotate and place until the outline is filled without overlaps. Early puzzles teach the language of shapes; later ones ask you to see negatives, not just blocks. How to play Drag tans from the tray, rotate and flip them, and fit the outline exactly; optional hints nudge orientation without giving away the whole answer. Keyboard controls Mouse/touch drag; A/D (or Q/E) rotate; F flip; Z undo; R reset; H hint. Tips & strategies Start with the largest pieces to claim anchor corners; pair the two small triangles into a “diamond” to test tight spaces; if you’re stuck, pull everything out and rebuild from a different corner; and step back for ten seconds—fresh eyes spot symmetries your brain filtered out.
