Each cell in a Rokrusi contains a nought or a cross.

The required number of crosses per row/column is shown on the right/bottom (after the dash).

In a standard Rokrusi, two crosses may not be diagonally adjacent to each other.

In the 'Knight Jump' or 'KJ' variant of Rokrusi, two crosses may not be at a knight's jump distance.

Tap or click a cell to put a nought or cross in it or to clear it.
