In the first game, there are nine numbers, 1 2 3 4 5 6 7 8 9. You and your opponent take turns, taking one number each time. You can only take a number once, so if your opponent has taken a number, you can't take it also (and neither can your opponent, again). The winner is the first person whose numbers total 15.

Here's an example:

You Your opponent 1 2 3 4 5 6 7 8 9 You take 1 2 3 4 5 6 7 8 9 1 Opponent takes 8 2 3 4 5 6 7 9 1 8 You take 5 2 3 4 6 7 9 1,5 8 Opponent takes 4 2 3 6 7 9 1,5 8,4 You take 9, and win! 2 3 6 7 1,5,9 8,4
