It is a game to find 4 digits facing off against your iPhone or iPod touch.

Guess 4 digits. The game system compares it with opponent's digits. If there are same digits on same place, the system judges "Hit". If there are same digits on different place, system judges "Blow".

For example, if you guess 0123 and com's digits are 1420, system gives you "1-Hit and 2-Blow".
These Hits and Blows work as clue for next guessing.

If you find the correct digits in smaller times than the opponent, you win the match.

You can play on locla or Bluetooth.

On local, your wins and draws are converted to points and ranked in the Game Center.
