## What is Prism?

Prism is a precise light-routing puzzle where light is the interface. Rotate mirrors, route beams, use color filters, and illuminate every target with the right wavelength.

Begin with a short interactive lesson, then return for a fresh Daily Challenge. Build a streak, beat par, explore a 42-level Journey across six optical worlds, and learn prisms and beam splitters in the Optics Lab. Later worlds use longer 8x8 dual-beam routes designed for experienced puzzle players.

A COMPLETE OPTICAL REDESIGN
The board, beams, glass optics, Home, Journey, Optics Lab, and Prism Vault now share one focused optical-instrument language. Clear hierarchy, restrained surfaces, and responsive layouts keep attention on each light path across iPhone and iPad.

HOW TO PLAY
• Tap a highlighted mirror to rotate it.
• Mirrors turn light by 90 degrees; filters change its color.
• Route every beam to its matching target.
• Solve at or below par to earn three stars.

KEEP DISCOVERING
• A fresh Daily Challenge every day.
• 42 Journey levels with a steady difficulty curve.
• An on-device Weekly Challenge with a personal best and a Monday reset.
• Three rotating Daily Goals, streak milestones, and gameplay rewards.
• Monthly on-device seasons have a fixed goal of 15 Daily Challenge completions. Reaching it records a cosmetic collection frame; Prism Pro members also unlock the matching board aura. Every season reward has a fixed requirement and never uses a random draw.
• Four Practice difficulties from Easy to Expert.
• Optics Lab experiments featuring prisms and beam splitters.
• A Spectrum Archive of optical artifacts earned with Light Energy.
• Prism Vault with 36 cosmetic auras across six optical series. Light Tickets come only from play; base odds are published; unowned items in the rolled rarity are selected first; duplicates become Prism Dust; draw 10 guarantees Rare or better, and draw 30 guarantees Legendary.
• Clean image sharing after a solve.
• Haptics, color labels, patterned beams, VoiceOver labels, and Reduce Motion support.
• Traditional Chinese and English interfaces.
• No ads. No accounts. No tracking. Puzzle progress and collection state stay on your device.

## Version history (last 5 releases)

### 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.

### 1.7 — 2026-07-25

Prism has been visually rebuilt around one idea: light is the interface. The board, beams, glass optics, Home, Journey, and Prism Vault now share a focused optical-instrument language.

Beyond the 42-level Journey, an on-device Weekly Challenge, three rotating Daily Goals and streak milestones offer new ways to play. Solved puzzles can be shared as clean image cards; Prism Pro gains expanded streak protection; the Vault now holds 36 cosmetic auras across six optical series.

Accessibility remains built in with color labels and beam patterns, VoiceOver labels, 44-point touch targets, haptics and Reduce Motion support. Layouts are refined for iPhone and iPad. Published Vault odds, gameplay-only Light Tickets and offline-first play remain unchanged, with no ads, accounts or tracking.

### 1.6 — 2026-07-14

Prism 1.6 turns every return visit into a clearer optical mission.

• Rotating Daily Goals and a deterministic Weekly Challenge with on-device personal bests
• Streak milestones, clearer protection history and new cosmetic rewards
• Refined Home, onboarding, completion, Journey, Vault and Settings flows
• 36 distinctive cosmetics across six series, plus clearer crafting and guarantee progress
• Clean 1080 × 1350 result cards built for sharing
• Larger optical controls, better level guidance and more responsive iPhone and iPad layouts
• Contextual Prism Pro presentation using live StoreKit prices and eligible offers only
• Privacy-respecting crash diagnostics and optional anonymous usage statistics; no ads or cross-app tracking

### 1.4 — 2026-07-11

Prism's biggest update yet:

- Journey: 28 increasingly challenging levels with 1-3 star mastery
- Spectrum: collect 12 light artifacts as you solve
- Optics Lab: six new prism and beam-splitter experiments
- A redesigned home, game board, onboarding, stats and Prism Pro experience
