Each player shuffles his/her deck and lays it FACE DOWN
A timer calls out: “Go!” and times 1 minute.
Each player flips over one card at a time and calculates a running total of the values on the cards.
After one minute the person keeping time shouts “Stop!”
Players write down their total e.g. 32 for this set of cards:1 + 4 = 5; 5 + 10 = 15; 15 + 3 = 18; 18 + 10 = 28; 28 + 4 = 32
Players check each other’s totals.
The winner is the one with the highest total. You cannot win if your total is wrong.
