App Description

Feel a little stressed out by the busy life? Try have some fun! 1A2B lets you enjoy the simple logic game without taking too much time!

This game is the same as another game called cows and bulls. You will plug in different series of numbers and the game will tell you how many cows (B) and how many bulls (A) you have. Bulls are numbers that are in the correct position and Cows are those that are the right number in the wrong position. So in this game the cows and bulls do not overlap. So if I type in “1234” and the game gives me 2A and 0B then I have two numbers in the right spot. When I try “1564” I get 1A and 2B meaning that either the 1 or the 4 is in the correct spot and 5 & 6 will more than likely be numbers in my pattern.

1. 8 times to guess 4 unduplicated number;
2. 10 times to guess 4 unduplicated number;
3. 12 times to guess 5 unduplicated number.
