LUCID is designed to run smoothly on most Android devices. If you experience performance issues, try closing other apps running in the background. The game requires Android 7.1 (API 25) or higher.
Win the previous level to unlock the next one. Beat RÊVE to unlock SONGE, beat SONGE to unlock LUCIDE. Chain Mode unlocks after your first victory on any level.
Every board is generated from a unique seed (shown as a hex code like #A3F2). Share it with friends so they can play the exact same puzzle and compare strategies.
Chain Mode is an infinite gauntlet of escalating arenas. You play RÊVE, then SONGE, then LUCIDE, then increasingly harder variants. One defeat ends your run. Your score accumulates across all arenas.
No. LUCID works 100% offline. No accounts, no ads, no data is ever sent anywhere. All your progress is stored locally on your device.
