Jumbo Cactpot Winners

[Cnidarian]

That's exactly how I thought it would be run - all numbers entered would be put into a draw to guarantee at least one winner per week. The prize is so low (relative to a real lottery system) it seems strange to do it as a Random Number Pool system.

The problem with that method is that people would start to band together to all choose the same numbers. This would boost the odds of winning significantly. Any system that isn't left to complete RNG, players will find an exploit and abuse it.

Needs to be changed to a raffle rather than a lottery.
1 ticket costs 10k gil. 5 for 40k and 10 for 80k. Like a real raffle.
Always a winner every week.

I would also allow people to purchase 10,000 mgp certificates (with their aquired mgp. Maybe a cost of 1k gil and 10k mgp per certificate) that can be traded and sold. Great gil sink and options for those that are unlucky to buy expensive items.
