5555xPrism

Plan a beam through a calm collection of compact prism puzzles.

Each board is a small spatial challenge built around one clear idea: rotate prisms, watch the whole route change, and guide the beam through numbered nodes in order before it reaches the finish.

Features:

• 72 handcrafted boards with a gentle increase in complexity.
• Immediate route recalculation after every rotation.
• Clear feedback for loops, blocked paths, boundary exits, and nodes reached out of order.
• Undo for recent turns, plus a full reset when you want to rethink the board.
• A move limit that rewards careful planning without adding a timer.
• One-to-three star ratings based on the efficiency of your completed route.
• Local progress and best ratings saved on your device.
• An offline-first experience with no account or network connection required.

Prism puzzles are designed for a few thoughtful minutes during a break, a commute, or a quiet evening. There is no pressure to act quickly. Study the geometry, make one turn, and let the route reveal what changed.

The challenge comes from seeing relationships rather than tapping quickly. A prism that looks distant can reshape the entire beam, while a small correction near the start can open a clean path to every node. Replay boards to improve your rating and learn to read the weave at a glance.
