The aim is to align five marks, in any direction, to beat the computer. The numbers are selected at random and are shown in the lower left–hand corner.  If the selected number is “B4”, click on your side ( the left side) the number 4 under the letter B, if it’s on your card.  A mark will appear.  If you forget, you’ll lose this mark.   The computer never forgets its mark.  


If you don’t have the selected number,  click on the «Play on»button.
