Looking for simple points betting script (not money). User creates account and is awarded X amount of points. Bets on compititions like a horse race, including odds. 1st place 2nd etc. After event I, via an interface put in the winners etc. and it deducts / adds points to the user. Don't need fancy graphics etc. main focus is on security and ability for me to manage in a simple way. Top 10 of points leaders would be nice.
