Provably Fair Competition
Before ticket sales begin, the instant win positions are generated at random and sealed, so nobody knows which tickets will win them. The method for picking any grand prize winner is sealed too, but that winner can't be known until the competition closes. The fingerprint below was published before sales, so nothing can be changed without it showing.

Displayed ticket numbers are a scrambled one-to-one mapping of draw positions, so sales volume can't be inferred while tickets are on sale. The mapping seed is revealed after the draw, letting anyone recompute the draw position behind every displayed ticket number and confirm the winners above.
