Playing for Cash Logic Puzzle

Playing for Cash

Four jolly men sat down to play,
They played all night until the break of day.
They played for cash and not for fun,
with a separate score for every one.
When it came time to square accounts,
they all made quite fair amounts.
Not one lost and all gained.
