## Description
A Logical Colors puzzle consists of an array of colored blocks. The color of most blocks can be changed by touching them. However, a few of the blocks are locked; their color cannot be changed. The first screenshot is an example of a typical puzzle.
Solve the puzzle by changing colors until each block is one of just two colors. Logical Colors has three rules limiting the way these two colors are to be arranged:
Rule 1: Every row and every column must have an equal number of blocks of both colors.
Rule 2: No row and no column may have more than two adjacent blocks of the same color.
Rule 3: There may be no duplicate rows or duplicate columns.
Changing block colors as specified by these rule results in the second screenshot; which is one block away from the solution to the puzzle.
Solve 10 puzzles to open the next level of difficulty. Solve a total of 25 puzzles to obtain access to the complete range of puzzles.
Logical Colors puzzles are problems in logic. Every puzzle can be solved by careful observation of the three rules. Some may be quite tricky, but guesswork is never necessary.
