lol it doesnt work with balls ( like regular lotto ), rather with tickets... you buy tickets, these go into a draw-pool, winning tickets are selected from the pool.

lottery guarantees that all revenue is being pushed out minus a servicefee between 0.1 and 1.5%. depends on the draw type.

so guaranteed winners. its also multicurrency but in beginning exclusively for bitstar.

when roi is met, the servicefee will become lower.

still working on it. its phase 3 yes.
