Fields are either black or not. The games objective is to mark the correct fields black. There are two shades of gray to denote non-black fields. So you can mark fields as "not black for sure". To mark a field black click on it. More clicks (or right mouse click) will step through the three states.

You can drag the red circles. This selects a "line" of fields on the board (in red). The number on the left labeled

Typing a number over the board will restart the game with a board of the size of the i-th prime (0->2, 1->3, 2->5, 3->7 and so on).

If you found a systematic way to solve the puzzle, then you understood the principle of the inverse Radon transform (at least in a finite field setting...:-))
