DEcoDLE

Rhythm meets puzzle. Crack it.

DEcoDLE: The Journal Logs A six-week serialized fiction. Two AI systems have been disagreeing internally, now the disagreement is public. Follow along - X: @decodle_app DEcoDLE is not a word game. It's not a rhythm game. It's both — and you have to earn every guess. Before you can attempt to decode a 5-symbol sequence, you must crack the Acoustic Cypher — a beat-matching round where you tap symbols in sync with a rhythm track. Nail it in one clean cycle and you unlock Perfect Sync rewards. Less than perfect with the beat and you still get your guess — but the rewards stay locked. Casual mode makes the Cypher accessible to everyone — the puzzle rewards are yours regardless of rhythm skill level. Every round the Cypher gets faster. Every wrong guess costs you a round. Six attempts. Six Cyphers. One sequence to crack. HOW IT WORKS — Tap symbols in time with the beat to complete the Acoustic Cypher — Earn Byte Tokens for Perfect Sync — spend them on Hacks, Hints, the overpowered AI+ Assist, and more — Use your DEcoDLE row attempts to guess the hidden 5-symbol sequence — Colored feedback shows what's correct, what's close, and what's wrong — Solve it in fewer guesses for a higher DECRYPT SCORE MODES — Daily: one shared puzzle, every player, every device, every day — Endless: infinite puzzles, play as long as you want — Challenge: encrypt your own 5-symbol sequence, generate a DC-XXX code, send it to anyone CHALLENGE ANYONE Pick your 5 symbols. Generate a code. Send it. They download DEcoDLE, enter the code, choose their difficulty, and try to crack what you built. Results come back as a shareable score card. No accounts. No servers. Just a code and a dare. DIFFICULTY — Casual: tap each shape across multiple cycles — anyone can crack the Cypher, skill determines how fast. Puzzleboard solving is fully rewarding here — Perfect Sync is achievable, the Rewards screen is open, and Byte Tokens are yours to spend. — Hard: faster patterns, challenging timing. 3–5 symbol/beat sequence patterns, higher speed curve — experienced players will want to start here. 1.5x score multiplier — Expert: insane precision timing required. Only 5 DEcoDLE row attempts by default. Use of Perfect Sync Bonus Rewards strongly encouraged. 2.0x score multiplier GRADED BY THE MACHINE :/System> is watching. Every session ends with a Cypher performance grade — FLAWLESS.EXE, S ELITE, A BRILLIANT, B SOLID, and down from there — plus a dry, sardonic verdict from the System. It has opinions. It will share them. DEcoDLE is free to play. Hard mode and Expert mode available with PRO.
