How the Odds Engine Works
Each preset defines a probability threshold for every prize tier. When you scratch, this simulator draws a single random number and checks which tier's range it falls into — so a ticket lands in exactly one outcome (a specific prize tier, or no win), never more than one, just like a real scratch-off's fixed print distribution.
The near-misses you'll sometimes see are a real side effect of the ticket's match-format grid, not something added on top — they happen at whatever rate pure chance produces.

Frequently Asked Questions
Does this simulator use real money?
No. Nothing here is real currency — "cost" and "prize" are simulated numbers only, so you can experience the odds without any financial risk.
Does buying a whole pack guarantee a profit?
No. While packs guarantee a set minimum of small tier prizes, the total payout of a single pack almost never exceeds the retail cost of the entire pack.
How can this help me understand risk?
By using the Fast Simulation feature (10x to 1,000x), you can immediately experience the mathematical reality of negative expected value without risking real money.
Why do near-misses feel so common?
This simulator's grid faithfully reproduces a real scratch card's match-to-win format, where partial matches happen naturally by chance. Psychologists call the strong reaction to a close-but-losing result the "near-miss effect."
What is Return to Player (RTP)?
Unlike casino games (95–99% RTP), government and state lotteries typically return 50–70%. For every $100 spent, players mathematically recoup roughly $50–$70 on average over the long run.
Who built this simulator?
