DEcoDLE

DEcoDLE is a daily rhythm puzzle game where you must crack an Acoustic Cypher beat-matching round before every guess attempt. Decode a hidden 5-symbol sequence across up to 6 rounds — but first, you have to earn it.

Before you can attempt to decode the 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.

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

TWO CYPHER STYLES — NEW IN v1.1.0
The Acoustic Cypher now comes in two player-selectable styles.

ACOUSTIC CYPHER (CLASSIC) — the original. Symbols flash on the static
center monitor in time with the beat. Watch, listen, tap.

ACOUSTIC CYPHER EVOLVED (EVO) — the monitor becomes a rotating dial. The target symbol sweeps the ring, changing position and identity with every beat. Read the dial — tap each notch's symbol as the pin reaches it.

Switch anytime in Settings → Cypher Style. Scoring and rewards stay
identical in both.

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. 2–5 symbol/beat sequence patterns, very relaxed completion paths — anyone can start here
— Hard: faster patterns, challenging timing without Expert's unforgiving precision requirements. 3–5 symbol/beat sequence patterns, higher speed curve — experienced players will want to start here. 1.5x score multiplier
— Expert: even faster patterns, insane level of 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.
