The goal of this game is to cross out all numbers. It’s possible to cross out any of the same digits or giving 10 in total which are placed next to each other either horizontally or vertically. You can cross out the last item in one line with the first one in the next line if they are the same or gives you a total of 10. Numbers that have been struck out won’t be counted anymore. If there are no more moves, click the “Add numbers” button. All the numbers that aren’t crossed out yet will be rewritten lower and you can continue to play.
