An incentive prize competition should solve the grand challenge of making positive changes to lotteries.
There is huge potential to create positive impacts by making changes to lotteries, but lotteries have been relatively slow to make changes that benefit society.
Government bottlenecks, lack of market incentives, and other barriers prevent these positive changes.
An incentive prize competition should break through these barriers to enable changes that positively impact our world.
