About Gauguin
Gauguin is a Sudoku-like game where you solve grids via calculation and logic. You can use it to relax or to solve difficult grids to your opinion. In classic mode, you solve a 9x9 grid by typing a value from 1 to 9 in each cell such as - Each row and column contains each digit exactly once. - Each cage meets its given mathematical problem. E.g. a group of cells labeled with '5+' must be filled such that the sum of all digits is 5. Via game options, you may alter the game to solve other digits, smaller or greater grids, hiding the operators.
