Prism

Read full description

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.

Deduce who's who in an old Edo row house. Using the testimony clues, work out which resident has which job, which color their shoji screen is, which animal they keep, and what food they love. Fill in one logic grid, step by step, until the whole tenement makes sense. No guessing here: it all clicks into place by pure elimination. โ–  Three simple steps 1. Read the clues about the residents. 2. Tap the grid to mark each cell as a match or a no. 3. Fill it all in, then check. Solve it without contradictions to win. โ–  120 puzzles Five tiers, from Beginner to Master, for 120 puzzles in all. Rooms grow from three to five and attributes from two to four, so the challenge ramps up smoothly. โ–  Great for you if you - want a number-free brain workout - enjoy Einstein or zebra logic puzzles - love a calm, traditional Japanese setting - like to think things through in spare moments โ–  More to enjoy - Resident collection to gather everyone you meet. - Today's Row House, a fresh tough puzzle each day. - A friendly landlord guide, plus hints when you're stuck (reveal a cell, find a mistake). Follow the clues and enjoy the satisfying moment the truth falls into place. This is a work of fiction. All characters and shops are imaginary.
