static Jackpot:
you set a value (example: 100) for the Jackpot. This is a fixed value anybody will earn when playing a result that is the current Highscore for that Game.
It has nothing to do with the Score he played or the Costs he paid for playing.
raising Jackpot:
Jackpot starts with 0 and each time a player plays it, the Costs for the Game (example 100) get added to the Jackpot. This means in this example it raises 100, 200, 300 ...
If a player gets the current Highscore, Jackpot gets paid out and restarts at 0.
If you have raising Jackpots make sure to set lower Costs per Play so that the Jackpot won't grow too quick
In the vbPlaza-Settings you can even setup a percentage of how many Costs per Play get added to the Jackpot to reduce its growth
