Before You Draw
Remaining ≠ Remaining Prizes
Draw pools only show how many draws remain, not which prizes are still available.
Gambler's Fallacy
Don't think you're 'due' a win after several draws — each draw is independent.
Sunk Cost Trap
Money already spent doesn't affect the next draw result. Don't keep going just because you've spent so much.
Set a Budget Limit
Decide your maximum draws before you start, and stop when you reach it.
Buying Directly May Be Better
Calculate the expected cost to win a prize and compare with buying directly on the secondary market.
