This game will be 1 on 1. More like a trivia game.
Every time, they will have 1 question and 16 answers on the board. They have 16 answer but 1 right answer only. If one player figures out the right answer while they had 16 answers, he get 16000$, if 8 answers, he gets 8000$, if 4 answers, he gets 4000$ and if 2 answers, the person gets 2000$. If one person gets the wrong answer, while they had 4 answers left, we will do 16000$-4000$=12000$ and give that money to the opposite player. Every turn, if one person says split, 16 answers turn instantly to 8 answers, then 4, then 2. To win, you need 50000$. If no one could guess, and the person says split when they have 2 answers left, the question is over and the answer is revealed. But no one gets money. If you want, you could check out the computer for answers.
