How to play
[ Single Play ]
Find 4 numbers with the smallest score = Try times x Minutes.
When you find a number in the same place, then you will be given a hint as 1Hit. When you find a number but in the different place, then you will be given a hint as 1 Blow.
For example, if the 4 numbers are 0123, and you guessed them as 9135, then you will get hint as 1H1B.
