This idea is for the future when all of the little kinks are worked out.  

To encourage investment into the game do an underground league.  To get into the league you have to buy your way in, let's say 1€.  

League only lasts 1 week and the last teams in the league after the last game on friday split the pot.  If no teams make it to friday the winner of the last game wins the pot.  

1 game per day and instant elimination.  This is a world wide league.  64 teams can enter and have a a winner in the same week.

Sign ups start on Saturday and the First games are Sunday with the final on Friday.

If there is only 1 winner, the winner can only enter 1 time per 4 weeks, So the same teams can't win every week.

If more than 64 spots are allowed then different rules would have to apply.
