About this game

1A2B is a game that requires thinking.

"A" means that a certain number you guess is the same as a certain number of the answer, and their position is also the same.

"B" means that a certain number you guess is the same as a certain number of the answer but the position of the number you guess is wrong.

The following content refers to "3, 4 or 5 unique numbers" as "Numbers".

[for Phone and Tablet]
1.User guess (3, 4 or 5 numbers)
2.Machine guess (3, 4 or 5 numbers)

Before starting the game, the app will randomly generate Numbers.
After the game starts, you need to enter Numbers. When you press Done icon, the app will send back the result (e.g. 1A3B).
Repeat the previous step until you successfully guess the answer.

The more you practice, the faster you will get!
