Plus and Minus

A simple children's game requiring some basic mathematical skills, a score sheet and five dice.

Play:

Each player in turn has four rolls of the dice.  On the first roll a player sets aside two of the dice, totals them and notes his score on the score sheet.  On the second roll the remaining three dice are rolled and one is set aside and the value is subtracted from the player's total on the score sheet.  On the third throw the two remaining dice are rolled and one is set aside and it's value added to the player's total on the score sheet.  On the final throw the last remaining die is rolled and the value is subtracted from the player's total on the score sheet.  The final resulting number is the player's score for that round. 

Five rounds are played as before and the winner is the player with the highest total of points over all the rounds.

Example turn:

    Dice Rolled                 Dice Set Aside          Total
    6, 5, 2, 2, 1                      + 6, 5                           11
    5, 4, 3, 3                           -  3                                8
    4, 2                                   + 4                               12
    5                                        - 5                                 7 
                                                                   Score:    7
