The Forgotten Script
Read full descriptionHide full description
An ancient script lies scattered across forgotten ruins. Each glyph hides a letter. Each inscription hides a message. Your job: crack the cipher. The Forgotten Script is a meditative puzzle game where you decode encrypted quotes and inscriptions by mapping mysterious glyphs to letters. Start with a few revealed clues, then use logic, pattern recognition, and linguistic intuition to uncover the rest. EXPLORE THE RUINS Each run is an expedition through a series of rooms, each containing a new cipher to solve. Progress deeper, earn higher scores, and uncover increasingly complex encryptions across four difficulty levels — from Novice to Expert. DAILY CHALLENGE A new puzzle every day, the same for everyone. Compete on the daily leaderboard and build your streak. Miss a day? A free rescue is available once per month, and Pro members get a weekly streak shield. GLOBAL LEADERBOARDS Climb weekly and all-time leaderboards across three puzzle languages. Your best four runs each day count toward your standing — no need to grind endlessly. THREE PUZZLE LANGUAGES Decode ciphers in English, Turkish, and Spanish. Each language draws from its own unique bank of quotes and inscriptions, offering a fresh challenge for multilingual players. NO ADS. NO TIMERS. NO NONSENSE. The Forgotten Script respects your time. There are no advertisements, no energy systems, no wait timers. Play at your own pace, offline or online. FORGOTTEN SCRIPT PRO (Optional) A single lifetime purchase unlocks: • Expert difficulty level • Themed visual palettes — Desert Tomb, Jungle Temple, Crystal Cavern, and more • Access to past daily puzzles • Detailed stats and run history • Streak Shield — one automatic save per week The game is free to play.
