Light the orchard with logic. Fruitlight Doku is a fruit-lantern puzzle game inspired by Akari (Light Up). Place lanterns to illuminate every empty square. Lanterns must not shine on each other, and each numbered wall tells you exactly how many lanterns belong beside it. A LITTLE LIGHT, A CLEAR IDEA • Explore an illustrated orchard with a different cover for every chapter. • Learn through early puzzles, then take on increasingly challenging boards. • Play a daily challenge alongside the main journey. • Mark squares, undo moves and use explanations or reveal a lantern when you need a hand. • Earn light seeds through play and check every reward and expense in your history. • Enjoy layouts for iPhone and iPad, including landscape on iPad. • Choose English, Simplified Chinese, Japanese, German, Traditional Chinese, French, Spanish, Brazilian Portuguese or Korean. PLAY AT YOUR PACE The first 60 campaign levels are free. Later levels can be unlocked individually with light seeds earned in the game. Optional Fruitlight Doku Pro is a one-time in-app purchase that unlocks all campaign levels, grants 120 light seeds on first activation and increases first-clear rewards. Pro is not a subscription. Hints and reveals still use light seeds. TIMED CHALLENGE Solve a series of Light Up boards before time runs out. Start twice daily for free, or without a daily limit with Pro. A new run uses an attempt; resuming the same run does not use another. Game Center is optional. Core puzzles work offline. With iCloud enabled, supported progress and your Light Seed wallet can sync between devices using the same iCloud account. Optional repeatable consumable packs add 120 or 420 Light Seeds. Gameplay spending and rewards apply locally immediately; sync runs outside gameplay. Internet is required for wallet setup and purchase delivery. Restore Purchases restores Pro; finished consumables are recovered through the existing iCloud wallet, not granted again. Allow sync to finish before changing devices or deleting the app. Privacy policy: https://cgq-source.github.io/fruitlight-doku-support/privacy.html Terms: https://cgq-source.github.io/fruitlight-doku-support/terms.html ORCHARD EXPEDITION Follow a free five-stop route through the Mirror Grove. Fixed mirrors bend light, and repair puzzles ask you to move lanterns within a limited number of moves. Continue offline or replay completed stops. Expedition progress stays on this device.
