Objective: place most of your markers upon the board; improve the multiplication up to 100. - acting by turns – Each player gets his/her coloured markers/chips and rolls the 4 dice (with numbers up to 10): Form a square with the 4 dice and multiply either the horizontal, vertical or diagonal numbers: Both results may be marked with your chips on the board. Achieving a 9, 25, 49 or 81 you have a second turn, a ‘100’ gives you a third turn. If you cannot use numbers you loose that turn, game ends after all numbers are marked.
