Polygon Merge: Shape Idle

Drop shapes. Merge them. Seal them into the lattice, and let them pay you forever.

Polygon Merge is a merge puzzle that turns into an idle game. Every round gives you a fresh well and a five-minute clock. Whatever you seal before that clock runs out becomes permanent income that keeps earning while the app is closed.

HOW IT PLAYS
- Drag and release to drop a shape into the well.
- Two shapes of the same tier merge into the next one up: triangle, square, pentagon, all the way to a circle.
- Tap a grown shape to seal it. It leaves the well and takes a permanent slot in your lattice.
- Sealing is the whole decision. A shape you seal is a shape you can never merge higher, and the tier above is always worth more than the two below it.

WHY IT KEEPS GOING
- Your lattice earns every second, online and offline.
- Come back after a break and collect what your shapes earned without you.
- Four upgrade tracks: which shape lands in your hand, how wide the well is, how low you are allowed to seal, and how much each slot yields.
- Collapse the lattice to trade progress for cores, then rebuild faster than before.

BUILT SMALL
- No energy bars, no lives, no waiting to play the next round.
- A round lasts five minutes at most and always ends, so it fits a bus stop as easily as an evening.
- Portrait, one thumb, no tutorial wall.

Free to play, with optional rewarded ads and in-app purchases.
