Every game gets 0–100 from the official WA Lottery prize table:
- Payback (45%) — estimated cents returned per $1 on the tickets still unsold.
- Drift (30%) — payback now vs. at launch. Positive means big prizes are outlasting small ones.
- Big-prize share (25%) — share of the top 3 prize tiers left vs. share of all winners left.
- Games with every top prize gone are cut by 45% and marked Skip.
Chance to end ahead comes from 3,000 simulated sessions at your budget using the remaining prize odds.
Remaining tickets are estimated as overall odds × winning prizes left. The Lottery reports claimed prizes, so a recently won but unclaimed prize can still look available.
