Passcode Guesser

Crack the code in as few tries as possible. Now with HARD MODE — six digits, infinite guesses, one shot at the leaderboard.

PASSCODE GUESSER A retro phosphor-green code-breaking game. The system locks you out with a randomly generated passcode. Your job: figure it out, in as few tries as you can.

After every guess, the slots light up with classic Mastermind-style feedback: • GREEN — right digit, right position • YELLOW — right digit, wrong position • DIM — not in the code

Guess. Adjust. Guess again. The fewer attempts you need, the higher you climb.

— GAME MODES — • EASY — 4-digit passcode. Quick rounds, sharp deduction. • HARD — 6-digit passcode. For when 10,000 combinations isn't enough.

— FEATURES — • Local high score leaderboard, ranked by fewest guesses • EASY and HARD scores tracked separately so you always know what you cracked • Continue Game lets you walk away mid-attempt and pick up exactly where you left off • Authentic CRT styling: phosphor glow, scanlines, monospace type, retro keypad • Tactile beep, denied, and unlocked sound effects on every input • Full-screen, portrait-locked, no distractions, no ads, no tracking

— HOW TO PLAY —

1. Tap NEW GAME and choose EASY or HARD
2. Punch in your guess on the keypad
3. Read the colored feedback
4. Narrow it down until ACCESS GRANTED
5. Enter your initials to lock in your score

No timers. No lives. Just you, a number pad, and a code that doesn't want to be guessed.

Boot up the system and start cracking.
