Thinking of ways to add jackpot to the games - Any ideas?
Its good idea. I think it should have 2 jackpot there. Every game should have different jackpot and global jackpot for all games. Also we have choice to participate in the global jackpot or not with pay some satoshis there. I believe if jackpot added there many new player will interesting to try playing in you site.
How to make a universal jackpot?
it is easy to make a universal aka global jackpot
you just take a set % of every bet and add it to the global jackpot count,lets say 1% of HE for every bet,rounded
that would put additional load on the servers,though
the bigger problem would be how to determine the global jackpot winners,there would be different set of rules for each and every game
so it is easier and better to introduce separate jackpots for every game
or to create a "wondering" jackpot to promote games that are less popular at the moment
the options are limitless
