Eikonal vs Laser Box Puzzle

Eikonal is a physics-accurate optical puzzle game. Place and rotate mirrors, prisms, and lenses on a dark canvas, and watch real light rays bend, reflect, and split in real time. There is no submit button — the puzzle recognizes itself as solved the moment your ray field reaches every target. Named after the eikonal equation, the mathematical foundation of geometric optics, the game simulates light the way it actually behaves: angle of incidence equals angle of reflection, white light disperses into red, green, and blue through a prism, and lenses converge and diverge beams along their true paths. 100 PUZZLES ACROSS 5 CHAPTERS • Reflections — Mirrors. Bounce light to the target. • Refraction — Prisms. Split white light into its spectrum. • Convergence — Lenses. Focus and diverge beams. • Channels — Beam splitters and fiber. Guide multiple paths at once. • Caustics — Diffraction and curves. The master class. LIGHT THAT FEELS ALIVE Every move updates the entire ray field instantly. Nudge a mirror a degree and the whole scene of light shifts with it. The simulation runs continuously, so solving is a tactile, exploratory act — not a guess-and-check. DESIGNED FOR iPHONE AND iPAD Smooth, responsive ray tracing. Glowing beams against a near-black field. Built for iOS 17 and later, with full iPad support in every orientation. NO NOISE No ads. No in-app purchases. No accounts. No internet required. Just you, the light, and the puzzle. Solve with light.

Enter a compact optics lab where every move changes the path of light. Laser Box Puzzle is a spatial logic game about moving and rotating optical boxes. Guide the laser through every checkpoint and into the receiver to complete each circuit. Mirrors reflect the full beam around corners. Glass splitters transmit light while also creating a reflected branch. Move each optical box one cell at a time, rotate it into the correct angle, and watch the beam update instantly. FEATURES - Learn the rules through six handcrafted tutorial circuits - Continue with an unlimited supply of generated puzzles - Solve deterministic circuits built from guaranteed solvable layouts - Move and rotate mirrors and glass splitters - Route light through checkpoints, walls, and multiple beam paths - Earn up to three stars based on your number of moves - Undo moves or restart a circuit whenever you need - Keep your progress and stars saved locally - Use an extra mirror when you need another way forward - Enjoy responsive haptic feedback with an optional setting The generated circuits gradually introduce longer routes, more optical boxes, additional checkpoints, walls, and deeper scrambles. Every endless level keeps a stable layout, so you can leave and return without the puzzle changing. Extra mirrors are placed automatically in a random empty cell. The game includes three shared mirror credits. After they are used, additional mirrors can be requested by watching an optional rewarded ad. No account is required. Core puzzle gameplay is available offline, while an internet connection is required for advertising and related privacy controls. Move. Rotate. Illuminate.
