Let me teach you a new game. It's called "count to 5". Here are the rules.
So here's an example: Player 1 starts by adding 3, so the count is now 3. Then player 2 adds 1, so the count is now 4. Player 1 adds 1, to make the count 5, and loses the game.
Another example: player 1 starts by adding 2, so the count is now 2. Player 2 adds 1, so the count is now 3. Then player 1 adds 1, to make the count 4. Finally, plater 2 adds 2, to make the count 6, and plater 2 loses.
