Polyturn

Polyturn is a precision grid puzzle about guiding rigid multi-cell parts through narrow blueprint machine corridors.

Swipe left or right on the yellow piece to rotate it exactly 90 degrees around its active red pivot. Tap an adjacent open grid cell to move the entire piece one step. Every accepted move preserves the part as a rigid shape, while blocked rotations are rejected without partial movement.

Navigate pivot sockets that can transfer the active rotation center, pass one-way gates that close behind you, and align the final position and angle with the cyan assembly slot before the move budget runs out.

A Pivot Pin can transfer the active pivot to another marked module when the resulting route remains solvable. Optional rewarded videos on the home screen can add Pivot Pins, but they are never required to start or complete the game.

Features:
- Three deterministic, solver-verified puzzle sectors
- One-handed portrait controls
- Exact 90-degree rotations and grid movement
- Pivot transfers, one-way gates, and move budgets
- Persistent settings, best scores, and unlocked progress
- Blueprint machine artwork, sound effects, and background music
