Logic: code breaking is a free Android game developed by Logicom Apps that is based on a classic two-player code breaking puzzle board game that was popularized in the 70s. The game is also known as Bulls and Cows, and Numerello. With its flexible settings, this app allows you to adapt the game's difficulty to many of its variants.

In one player mode, the game generates a code that you must break with the least number of guesses to become the master code breaker. The game provides feedback for each guess, telling you how many colors are correct in color and position, or in color but not position. You can adjust the difficulty of the game in Settings by changing the number of rows, columns, and colors to find a suitable level for novices and experts alike.
