The Lottery Problem, sometimes known more specifically as the Lottery Wheel Problem is a problem in combinatorics and computer science that arises from a common gambling tactic used to guarantee non-jackpot wins at the expense of a higher initial investment.

This problem is intriguing from a computational perspective because it is difficult, but not impossible, to compute reasonably good solutions for real-world sized problems. Nevertheless, the question of how to efficiently generate optimal solutions seems to be presently unsolved. Also unsolved is the related question of whether or not this problem is in fact NP-Complete. The answer to this latter question would determine if generating optimal solutions is feasible at all.
