Jackpots would be technically quite a step, but I'm considering adding some shorter-odds games to have more frequent wins -

Some ideas that have been thrown around -

Betting on 1, 2 or 3 numbers -
Betting that no number drawn will be below X
Betting that no number drawn will be higher than X
Betting on the lowest number drawn
Betting on the highest number drawn

Having a Jackpot encourages playing tickets, because a large Jackpot potentially makes playing a positive EV game.

Also, any plan for a dice game?
