Sudoku Cafe

Sudoku Cafe is a Japanese number puzzle. This is a puzzle whose solution algorithm is based on the four basic laws of formal logic: 1) contradiction, 2) identity, 3) exclusion of the third and 4) sufficient reason. Despite these too clever words, the game process is guaranteed to bring intellectual pleasure to the players. In time, this pleasure feels like several hours become one minute. Do not take this comparison too literally – the Time Machine has not yet been integrated into games.
