Guide light. Find the angle. Bring every target to life. Prismelle is a light-and-logic puzzle game for iPhone and iPad. Drag prisms, mirrors and lenses onto the board, rotate them, and watch the light respond. Split white light into colors, reflect beams around obstacles and focus the path toward each target. The first 19 Classic levels and first 6 Refraction levels are unlocked for free. Without Pro, completing an optional rewarded ad unlocks up to 2 next locked levels in the current chapter. If only 1 remains, only that level unlocks. This applies to Classic (50), Refraction (19), Solar Journey (9) and Cosmic Journey (4). Solar and Cosmic are played on iPad in landscape; their levels 1–2 also require an ad before first entry. Complete Solar to access Cosmic. Chapter progression rules still apply. From version 1.0.5, non-Pro players may see occasional interstitial ads when continuing to the next level after a clear. These ads do not grant unlock rewards. Pro removes both rewarded and interstitial ads. Pro is a one-time purchase with no ads. It includes all four chapters on supported devices and the extra Solar/Cosmic achievements. While Pro is active, each level’s first-ever completion grants 1 shared hint; replays and levels completed before buying Pro do not grant this reward. The one-time upgrade bonus is 8 shared hints. Each run also has 1 exclusive hint, used first and not carried over. Restarting or reopening the same run does not replenish it. A new retail save starts with 8 shared hints. Game Center has separate completed-level leaderboards for Classic (50) and Refraction (19). Only distinct current levels count; replaying adds no score. Solar, Cosmic and tutorials do not contribute. More completions rank higher. Saved progress is submitted after sign-in or when connectivity returns. Purchases, localized prices and refunds are handled through Apple. Restore Purchases restores eligible Pro access, not deleted progress or spent hints. Optional iCloud sync in Settings merges supported progress and hint records in your private Apple iCloud account; historical timed-challenge records and device preferences remain local. Sync requires an available account, connection and storage. Deleting the app can remove local data; turning off sync does not delete cloud data. See the Privacy Policy for details.
