You will need:
All players begin by writing 50 on their score sheets.
The first player puts two dried peas into a plastic cup.
They toss the peas onto the game board, and add the two numbers that the peas land on.
They then take this sum away from 50 and write down the answer on their score sheet.
The next player takes a turn.
After the first turn, the players start with the new number written on their score sheet and take the sum of the numbers away from that, rather than from 50.
The first player to reach zero wins.
