How to play
- The hidden number has 4 different digits from 1 to 9 (no 0).
- Enter a 4-digit guess to get hints. A digit in the right place is a "Hit"; a right digit in the wrong place is a "Blow".
- Use the hints to guess again. 4 Hits means you cracked it.
In "Solo" you crack the number Shiro hid. In "Vs Shiro" you hide a number too and take turns with Shiro; the first to crack it wins, and if both crack it in the same round it is a draw. Choose Shiro's level: Easy or Hard. Shiro never sees your number — it guesses from the hints alone.
