Read the instructions carefully. You cant just win once. Thats no more difficult than a coin toss. You have to win with all 100 players. If you dont think its possible, Ive included a auto-run page which executes the correct strategy 100 times to show that you can win and quite often ( about 1/3).
"The Game" tab is where you will try your strategies. If you give up, you can always buy the solution at the bottom of the page.
GOOD LUCK!
