Joker Jewels

Joker Jewels is a quiet companion for exploring seven-piece tangram arrangements. It collects 35 abstract silhouettes, each with a solution built from the same seven polygons. Browse the collection by name or description, and narrow it with wide, tall and balanced filters. Every study opens a preview, a short outline summary and a practice hint. The board uses discrete controls instead of free dragging. Select a piece, then move it one grid unit at a time, turn it in 45 degree steps, or flip the parallelogram. A readout shows the exact position and rotation of the selected piece. Reset returns all seven pieces to their loose starting positions after a confirmation. Solutions stay hidden until you ask. Reveal the exact arrangement to compare joins and coordinates, then return to a board left exactly as you had it. The collection is stored on your device and works offline, with no account needed. Board practice is session only, so nothing is kept between visits in Joker Jewels.
