Game sweepstakes simply limit security at the end of the realization of

launched
colleagues said: "The lower limit of minimum guarantee is not the first time before many times, how many times not before The second, and so on. " First contact without understanding what it means when the lower limit of insurance at the end, because I "many times before" it wrong, I understand it has become "the props to be drawn up before many times", but "many times before" means how many times a player lottery draw. After figuring out that the lower limit of minimum guarantee is very simple.
The lower limit of the project is implemented as security at the end, very simple. The first is the number of lottery players to be recorded. Then configure the required lower limit of the minimum guarantee of props. Finally, according to the number of lottery player determines insured props can bottom to the player. Due to very simple, direct paste the code a Lua script.
