here's my suggestion for the operation before Christmas.
A game in the form of an Advent calendar.
Rules: Each day would open a mini game of the same How it Works as the Catch A Prize with about 15 boxes. But to be allowed to Play, you would have to have bought a certain number of credits during the day. Example: 4Credits on the 1st day and in the mini game winnings ranging from 5 madpoints to a bottle opener Someone who buys 32 credits that day could try his luck on the same mini game 8 times!
Example 2 : 10 days later, 100 Credits minimum with winnings in the mini-game ranging from 25000 madpoints to a Recent DVD or CD
And so on until New Year's Eve when we would have 675 Credits with winnings of 1 000 000 points to a Netbook/PSPGo....
It is evolutionary like the DreamCard and everyone has a chance depending on their purchases.
