Tangram Shapes is a puzzle book for the seven-piece tangram you already own. Pick a silhouette, then rebuild it with your own set — the wooden, plastic or paper one sitting on the table. There is nothing to drag around on screen. The app holds the shapes; the pieces are yours. 500+ SHAPES Animals, people, plants, letters and everyday objects. Every one is solvable with all seven tans: each piece used exactly once, no overlaps, nothing left over. Three difficulty levels, from a handful of clean right angles to shapes that will keep you turning pieces for a while. FIND SOMETHING TO SOLVE • Search by name • Filter by category and by difficulty • Show only the shapes you have not solved yet • Or press once for a random one HINTS, ONE PIECE AT A TIME Stuck on a shape? Reveal a single piece and carry on. Reveal another if you need it. Or show the full outline when you would rather just see how it goes together. The choice is yours each time, and nothing is revealed unless you ask. KEEP TRACK Mark a shape solved when you crack it. Star the ones you want to come back to. Your progress is stored on your device. Made for anyone with a tangram set in a drawer: children learning shapes, teachers with a box of them in the cupboard, and anyone who likes a puzzle they can solve with their hands. Works on iPhone and iPad, in light and dark mode.
