Official Prize Tracker
A bounded watchlist of Texas $5 scratch games using the operator's published printed-prize and claimed-prize tables. Each changed snapshot is archived so real movement can accumulate over time.

- Houston Texans: +5,642 printed prizes claimed; top prizes unchanged since 2026-10-16.
- Azulejos: +632 printed prizes claimed; top prizes unchanged since 2026-10-16.

Not current ticket odds. Claimed-prize counts do not tell us how many tickets remain unsold or where they are distributed. This tracker describes published prize claims; it does not rank games, predict a future ticket, or recommend a purchase.
How the Odds Engine Works
Every ticket uses one uniform random draw against cumulative prize-tier probabilities, so it lands in exactly one outcome: one prize tier or no win. Presets with a published full prize structure use the operator's published winning-ticket counts. Other presets are explicitly labeled as simulator models rather than official distributions.
How does this simulator calculate scratch-off odds and RTP?
For a published distribution, each prize-tier probability is winning tickets ÷ issued tickets. Return to Player (RTP) is Σ(tier probability × prize) ÷ ticket price. Speetto 1000 and Speetto 2000 use Donghaeng Lottery's published issue counts; the simulator calculates the displayed odds and return from those counts.
Are these the current odds for unsold real tickets?
No. Official-issue presets describe the published print-run distribution, not live unsold inventory. The simulator makes independent draws from that distribution; it cannot infer the current chance on a real unsold ticket from claimed-prize counts. Compare independent draws with a finite ticket issue.

Frequently Asked Questions
No. Nothing here is real currency; "cost" and "prize" are simulated numbers only, so you can experience the odds without any financial risk.
No. Buying a whole pack does not guarantee that the prizes inside exceed the pack's retail cost. Pack composition varies by lottery and game, so check the operator's rules for the specific ticket.
Use fixed batches or enter a budget to compare one simulated run with the current model's theoretical return, without risking real money.
This simulator does not add a separate near-miss probability. Its match-style grid is generated from the selected outcome model, so close-looking losing patterns can occur naturally by chance.
RTP is the expected payout divided by ticket cost over many plays. For presets with full published prize counts, this simulator calculates RTP as Σ(tier probability × prize) ÷ ticket price; presets without a full official distribution are explicitly labeled as simulator models.
