## What is Prism?

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
• A new daily commission is free to play. Take your time: no countdown or attempt limit.
• Prism Pro adds a workbench with three difficulty levels, using 4, 6, or 8 shared mirrors, plus the previous 30 daily commissions.
• Your light folio keeps up to 90 recent commissions on this device. Completed commissions still in the folio can be revisited without Pro.
• Share a challenge code when you choose. A friend can enter it and play the same puzzle free, without an account or subscription.
• 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.

## Version history (last 5 releases)

### 2.2 — 2026-10-27

Dual-light commissions are here.

Play a new free commission each day: one mirror setup must make both A and B work. Prism Pro adds a three-difficulty workbench and the previous 30 daily commissions, with no additional purchase for existing members.

Keep up to 90 recent commissions in your on-device light folio. Completed entries still in your folio remain playable without Pro. Share a challenge code so a friend can try the same puzzle free, without an account.

Your six original restorations, Daily Challenge, Journey, Lab, seasons, and Vault remain available. Existing progress stays intact. No ads, paid hints for commissions, or cross-app tracking.

### 2.1 — 2026-09-12

The Optical Atelier is open.

Restore six small optical pieces with a new kind of shared challenge: one mirror setup must work in two light states. Switch between A and B to inspect each route; every turn affects both. The first two complete pieces are free, and four more are included with existing Prism Pro.

The new home puts these pieces within reach, with clear paths to the Daily Challenge and your other puzzles. Atelier hints are free, with no timer or attempt limit. Your original Journey, Lab, Daily Challenge, season, and Vault progress stays intact. English, Traditional Chinese, accessibility options, and live App Store pricing remain available. No ads or cross-app tracking.

### 2.0 — 2026-09-03

Advanced optics arrive in Prism 2.0. The Optics Lab now contains fifteen focused experiments, including teleporters, one-way gates, and additive color synthesis. Learn how colored beams combine at a mixed-light target, then use clear directional markings to read each route before making a move.

Every new experiment is handcrafted, has a verified unique solution, and preserves all existing Journey, Daily Challenge, season, and Prism Vault progress. The interface remains fully available in English and Traditional Chinese, with color-independent symbols and Reduce Motion support.

Published Prism Vault odds, gameplay-only Light Tickets, live App Store pricing, offline-first progress, no ads, and no cross-app tracking remain unchanged.

### 1.9 — 2026-08-09

Monthly Seasons are here. Complete 15 Daily Challenges in a calendar month to add that month's seasonal collection frame. Prism Pro members who reach the same goal also unlock its matching board aura. Season rewards follow fixed play goals and never use random draws; progress stays on your device.

The Prism Pro screen now supports a clearer Free-versus-Pro comparison. Free-trial wording appears only when the App Store confirms eligibility, and every price still comes directly from the App Store in the player's local format.

This update also improves language, date, and number formatting and keeps local saves compact while preserving existing progress. Published Prism Vault odds, gameplay-only Light Tickets, offline-first progress, no ads, and no cross-app tracking remain unchanged.

### 1.8 — 2026-07-26

Hints now unfold in three steps, from a broad region to the exact optic and direction, so you can choose how much help to reveal. The hint control also becomes easier to spot when a puzzle has you stumped.

Prism now honors completed streaks with an encouraging recap, keeps the app icon badge in sync with the Daily Challenge, and guides a new player's first Daily win directly into their first Spectrum Capsule. You can also share deterministic puzzle links with friends—no account or leaderboard required.

This update also improves save recovery, puzzle-generation responsiveness, VoiceOver board descriptions, large-text layouts, reduced-motion behavior, audio loading, and Vault reliability. Published Vault odds, gameplay-only Light Tickets, offline-first progress, no ads, and no tracking remain unchanged.
