Over / Under

1. A random number 0-100 is generated every Round.

 

2. Players bet on whether the outcome of current Round's Random Number will be:

-- higher than (over) the previous Round's Random Number. -- or
-- lower than (under) the previous Round's Random Number. --  

3. Losers pay Winners.

 

4. player_winnings = ( player_bet / winning_bets_sum ) * total_pot

 

5. If the random number is the same as the previous number, or if everyone loses, the House wins the entire pot.
