Notrio

If you're a fan of logic puzzles like Sudoku, you'll definitely love Notrio.

Notrio is an elegant and challenging logic puzzle (same category as Sudoku, except that Notrio is prettier :D). If you're a fan of mind challenging games, Notrio is the perfect match for you.

[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, move to the bigger and harder ones.

Hope you like Notrio as I do. Thank you.
