NN567Gate

NN567Gate is a spatial puzzle game that challenges your ability to visualize and organize shapes in a confined space. Set inside a cylindrical vault, you must arrange polyomino pieces of various forms to fit perfectly within the circular play area.

Each level presents a unique set of pieces with different shapes and sizes. Tap a piece to select it, rotate it to find the right orientation, then tap a cell on the board to place it. The goal is to fit every piece without overlap or overflow. Limited swap moves allow you to retrieve misplaced pieces, but use them wisely as they are scarce.

Features:
- 10 progressively challenging levels with increasing complexity
- Diverse piece shapes from simple singles to complex pentominoes
- Limited swap system that rewards careful planning
- Circular vault boards that restrict placement options
- Blocked cells and special layouts that test your strategy
- Score tracking and level progression system
- Dark industrial theme with high-contrast visuals
- No internet connection required - play offline anytime

The game starts with simple shapes on small boards and gradually introduces larger boards, more pieces, and blocked cells that force creative solutions. Each level has a target score to achieve, and efficient use of swaps earns higher scores.

NN567Gate requires no special permissions, collects no data, and works entirely offline. It is a pure puzzle experience designed for short sessions or extended play.
