One mirror setup. Two light states to solve. In Prism, turning a mirror changes two light routes at once. Switch between A and B, inspect what your adjustment changed, and find one arrangement that lights every target in both states. Helping one route can break the other. That is the puzzle. DUAL-LIGHT COMMISSIONS โ€ข A new daily commission is free to play. Take your time: no countdown or attempt limit. โ€ข Prism Pro adds a workbench with three difficulty levels, using 4, 6, or 8 shared mirrors, plus the previous 30 daily commissions. โ€ข Your light folio keeps up to 90 recent commissions on this device. Completed commissions still in the folio can be revisited without Pro. โ€ข Share a challenge code when you choose. A friend can enter it and play the same puzzle free, without an account or subscription. โ€ข Hints, undo, and restart are available while you work. Commission hints do not cost tickets or money. THE ORIGINAL OPTICAL ATELIER Restore six small wonders: a lighthouse, a greenhouse, a constellation clock, a rain-streaked window, a film projector, and a deep-space relay. Two complete pieces are free; four more are included with existing Prism Pro. MORE WAYS TO FOLLOW THE LIGHT The original Daily Challenge, 42 Journey levels across six worlds, four Practice difficulties, and 15 Optics Lab experiments remain. Explore teleporters, one-way gates, and additive color synthesis. Return to local Weekly Challenges, Daily Goals, monthly seasons, the Spectrum Archive, and your collection. Prism Vault contains 36 cosmetic auras across six series. Published base odds are Common 70%, Rare 25%, and Legendary 5%. After nine consecutive Common draws, the next is Rare or better; Legendary is guaranteed within thirty draws. Unowned items in the rolled rarity come first. Duplicates become Prism Dust for fixed-cost crafting. Light Tickets come from play, with one daily bonus for Pro; tickets cannot be bought or traded. Cosmetics never change puzzle difficulty or scores. PRISM PRO The dual-light workbench and 30-day commission archive are included with existing Pro. Pro also includes all six original restorations, the complete Journey and Spectrum Archive, expanded Practice and hints, the complete original Daily Challenge archive, visual themes, detailed stats, and expanded streak protection. Choose a monthly or yearly auto-renewable subscription, or a one-time Lifetime unlock. Prices are shown by the App Store in your local currency. No additional purchase is needed for current Pro members. Today's commission and shared challenge codes remain free. English and Traditional Chinese. Color labels and patterned beams, VoiceOver labels, haptics, and Reduce Motion support. No ads, accounts, paid puzzle advantages, or cross-app tracking. Progress stays on your device. Sharing opens only when you ask; Prism does not host player messages or a public puzzle feed.

PRISM

Turn a mirror and the light finds a new path. Guide the beam through every gem, then into the exit. There is always exactly one true answer. PRISM is a quiet logic puzzle made of light and mirrors. Tap a mirror to flip it between "/" and "\", route the laser through every glowing gem, and land it in the exit to win. The beam redraws instantly with every tap, so you can test ideas and watch them play out. Decoy mirrors that aren't part of the solution create convincing wrong paths, so tapping around won't get you there. PLAY WITH PEACE OF MIND - Free to start. Premium is a single one-time purchase, with no subscription - No third-party ads - Your records stay on your device FEATURES - One-tap controls: just rotate mirrors - Every board has exactly one solution path, so it's logic, not luck - Four difficulty levels (8x8 to 11x11), from gentle to brutal - A daily puzzle with a solving streak - 16 achievements, plus a clear celebration for personal bests and badges - Stats for solves, average time, and no-hint rate - Board color themes: Sky, Gold, Indigo, Jade, and Sakura - No account needed, and it plays offline - English, Japanese, and Spanish GREAT FOR - Turning a commute or coffee break into ten minutes of focus - Fans of logic puzzles that reward reasoning - Anyone who finds most puzzle apps too easy - People who like calm, minimal design - A one-puzzle-before-bed ritual PRIVACY Your records are never sent anywhere. No account, no personal details, no tracking. To introduce our other apps, PRISM may load public App Store information such as app names and icons. PRICING Free players get Easy and Medium, two plays a day (the daily puzzle doesn't count), and one hint a day. You may see cards introducing our other apps. A one-time "Premium" purchase (not a subscription) unlocks: - All difficulties, including Hard and Expert - Unlimited plays and hints - Best times by difficulty and your daily history - Color themes (Gold, Indigo, Jade, Sakura) - No app introduction cards Use "Restore Purchases" after reinstalling or switching devices. FROM THE DEVELOPER Hi, I'm TORANKIRITE. I wanted a calm place to use my head, with no luck and no noise. I hope the quiet click of the light lining up becomes a small, good part of your day. Feedback is always welcome from the app's settings.
