Sevenfold Tangram Shapes

Sevenfold is a quiet, offline tangram puzzle for anyone who loves shapes,
patterns and a satisfying click when a piece finally fits.

Every classic tangram set is made from the same seven pieces, or "tans": two
large triangles, one medium triangle, two small triangles, a square and a
parallelogram. Sevenfold gives you all seven in jewel tones on a warm cream
paper background, and asks you to fold them — drag, rotate in clean 45-degree
turns, and mirror the parallelogram — into sixteen classic silhouettes: a
cat, a house, a sailboat, a bird, a dancing figure, a fox, a rabbit, a swan,
a fish, a turtle, a heart, a diamond, an arrow, a tree, a rocket and a candle.

HOW IT WORKS
• Puzzles — browse all sixteen silhouettes in a grid and pick one to fold.
• Play — the active board. Drag any tan into place, use the rotate buttons
for exact 45-degree turns, and flip the parallelogram when a mirror image
is needed. Pieces glow and settle into place the moment they're correctly
aligned, with a soft vibration to confirm it.
• Sandbox — no target, no clock. Arrange the seven tans into anything you
like, just to play with the shapes.
• Stats — see how many silhouettes you've folded and your best time on each.
• Learn — a short how-to-fold guide plus a handful of awards to unlock as
you go, from your first solve to folding the whole set.

WHY SEVENFOLD
• Sixteen hand-arranged silhouettes across animals, people, places, symbols,
nature and sky.
• A calm, tactile design: jewel-toned tans on soft cream paper, gentle glow
feedback, no sound — just visuals and a light vibration.
• A real geometry engine underneath: every piece is placed and checked with
proper rotation and mirroring math, not a simple picture swap.
• Completely offline. No ads, no accounts, no analytics, no internet
permission at all. Your progress is saved only on your device.

Whether you're folding your way through the full set or just rearranging
tans in Sandbox for a few quiet minutes, Sevenfold is built to be a small,
handsome puzzle you can return to any time — no connection required.
