Find the patterns that are hidden inside the grid. Click on the blocks to change their state: blue is a correct guess, red with a cross inside is an empty spot, and grey with a question mark is an unknown spot. The numbers on the bottom and right side indicate how many hidden spots are in that row or column. When you've found all the hidden patterns and only those are indicated as correct guesses, you win! At the right side of the grid you'll see which cube combinations are hidden in the grid.
