[RULES]
Simple. Fill the grid with Coral and Turquoise squares such that:
[1] Three consecutive squares MUST NOT have the same color, and
[2] Each row and column has an EQUAL number of Coral and Turquoise squares.

[HOW TO PLAY]
Tap on a square to change its color as per the sequence:
Empty=>Coral=>Turquoise=>Empty

Please follow the walk-through included in the tutorial to gain more knowledge of the basic Notrio solving techniques.

This version introduces thousands of puzzles of 4 sizes & 4 grades:
• 4 sizes: 6x6, 8x8, 10x10 and 12x12

You may want to start with Easy 6x6 puzzles and once you get comfortable solving them, challenge your mind with the bigger and harder ones.
