About this game
A brain-burning deduction game: the app secretly builds a no-repeat digit code whose length you choose (3–6), plus a handful of starter clues (3–6). Each clue is a code annotated with how many digits are right (in the code) and how many are in the exact right position. Type your own guesses on the touch keypad — every guess turns into a new clue — and close in on the answer. The fewer steps you take, the more it gushes; nail it first try and you're a genius, and win streaks let you brag with a one-tap share. Fewest-steps and streak records are saved locally.
How to play
- Pick the code length (3–6) and number of hints (3–6), then start.
- Read the clues: right-digit = values in the code, in-place = correct positions.
- Type a no-repeat code on the keypad and confirm — it becomes a new clue.
- Get every position right to crack it — fewer steps earns higher praise.
