Games and Winning Strategies

Numbers can be used in fun games where you need to think ahead and plan to
win.
Game #1: The Game of 15
Rules:
 Players take turns picking a number between 1 and 5.
 The number they pick is added to a running total.

 The first player to make the total reach 15 wins.
Winning Strategy:
 To always win, try to leave the total at 10 after your turn.
 For example, if your opponent picks numbers that make the total 9,

you should pick 1 to bring it to 10. This way, you can control the
game and eventually reach 15.

Game #2: The Game of 50
Rules:
 The first player picks a number between 1 and 7.
 Players take turns adding a number between 1 and 7 to the running
total.
 The first player to make the total reach 50 wins.
Winning Strategy:
 Aim to make the running total hit key numbers like 43, 36, 29, or 22.
 If your opponent leaves the total at 42, you should add 1 to make
it 43. This gives you an advantage to win the game.
