The Lottery is a feature in Shadow Hearts. If you have a Lottery Ticket, you can talk to different 'lottery members' (NPCs across the game world), and play the Lottery.
Playing the Lottery Edit
When you have a Lottery Ticket, which are found either on the ground, in chests, or after defeating certain enemies, and you have talked to a lottery member, a Judgement Ring appears on the screen, with four hit areas - Red, Yellow, Blue and Green. The idea is to press x to slow down the ring, and to get a certain item by hitting one of the hit areas. Red is the best, then Yellow, then Blue, then Green, and if you miss you get Tissues (Which are actually needed in one of the Sidequests). Generally, you want to aim for the Red.
