Super Brain: Tangram is a puzzle app that trains spatial composition, shape decomposition, and local matching. Inspired by classic tangram examples, players observe target shapes such as swans, rockets, robots, cats, fish, houses, sailboats, bridges, windmills, cranes, castles, and deer, then choose seven colored polygon pieces from the tray and place them into matching outline regions on the main canvas. The app provides automatically generated levels that cycle through animals, buildings, vehicles, and objects, with mirrored, scaled, and shifted variants. Issues are generated from complete seven-piece polygon layouts, while the initial canvas shows only placeable outlines and hints. The answer page includes persistent colored target preview, piece-placement progress, outline canvas, selected-region highlight, wrong-placement shake, piece removal, and completion pulse feedback. Short description: Choose seven puzzle pieces and fill the target shape!
