How to play

You and your open get four random numbers. You both choose any numbers, then they are compared. You do it 3 more times. Then if you had less bigger numbers than your opponent, you lose one life, otherwise opponent loses one life. If you had the same amount as an opponent you both stay alive. You have 3 lifes. You can swap your numbers with opponent once in a round.
