Random Lottery

A unique and completely random lottery system where players can spend their tokens for one of a hundred prizes currently featured in the lottery. The prizes range in value from completely worthless to extremely invaluable and unique to the lottery. The project runs completely off of vanilla commands and command blocks, and requires no repeating blocks.

Some examples of the better prizes available:
Elytra
Mending Book
Llama Spawn Eggs
Charity Diamonds (Every player online gets a diamond, except for the one who hit the lottery).
Lottery Diamonds (One random player gets 3 diamonds).
Custom Potions unique to each administrator.
Dye Chest (Chest with every dye available in-game).
Musical Chest (Chest with every music disc available in-game).
