Refract Puzzle Game vs Eikonal

Bend the light. Find the path. Refract is a neon logic game about placing mirrors and watching a beam come alive. Route light through compact boards, illuminate every target, and find the cleanest possible solution. BEND EVERY BEAM • Drag mirrors from your tray onto the grid • Tap a placed mirror to rotate its reflection • Watch the full route update as you experiment • Undo a move, reset the board, or use a hint when you need a nudge • Light every target to complete the puzzle MASTER THE SPECTRUM • Solve 100 levels across 10 distinct worlds • Begin with simple reflections, then face blockers and checkpoint routes • Split one beam into multiple paths • Tint light at a prism, then prove its color at a gate that absorbs any beam that does not match • Carry beams through linked portals • Combine every mechanic in the final mastery worlds CHASE THE PERFECT ROUTE Every board awards up to three stars. Finishing earns the first. Solving within a comfortable move budget earns the second. The third asks for a clean run: inside par plus two, with no hints and without clearing the board. Taking a mirror back off the grid is always free, so exploring an idea and changing your mind never costs you a star. Only the moves you keep count. EVERY BOARD STAYS REACHABLE A level opens once either of the two before it is done, so a single puzzle you cannot crack never blocks the rest of the campaign. Worlds open on stars you have already earned. RETURN DAILY A featured challenge changes every day. Solve it to earn bonus coins and gems, then come back tomorrow for a new route. MAKE THE GRID YOURS Earn coins and gems by playing. Spend them on hints or unlock atmospheric board themes including Solar Flare, Arctic Prism, and Ember Void. Optional App Store purchases offer another way to unlock the same kinds of items. DESIGNED TO FEEL GOOD • High-contrast neon visuals, with light that visibly travels along the beam • Clean chimes for lit targets and solves, mixed so your own music keeps playing • Responsive haptics for moves, invalid drops, and successful solves • Colorblind assist gives every beam color its own distinct shape • VoiceOver labels and board actions • Dynamic Type and Reduce Motion support • Sound, haptics, motion, and colorblind assist all toggle in Settings • Portrait play designed for iPhone and iPad The full 100-level campaign is free to complete. Refract has no ads, subscriptions, accounts, analytics, or tracking. Progress and preferences stay on your device. Requires iOS 17 or later.

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.
