Every convenience store in Korea stocks eight different rounds of Speetto instant lottery tickets at any given time. Most people just grab one at random—but here’s the catch: even though they all cost the same, the odds shift dramatically round to round. Some rounds are statistically favorable right now. Others have already exhausted their top prizes. Most players never know the difference.
I built this app because I got tired of guessing. I wanted a simple way to see which rounds were actually worth buying before heading to the store.
What It Does
- Compares all active rounds at a glance. The app pulls live data from Donghang Lottery’s public database and shows you every round currently for sale, ranked by statistical advantage. It highlights which round offers the best expected value today.
- Finds golden-window rounds. These are rounds that have shipped over 95% of tickets but still have unclaimed top prizes—a rare statistical sweet spot worth knowing about.
- Filters by payout potential. Want to see only rounds with plenty of first-prize tickets still in circulation? You can isolate those instantly.
- Deep-dives into round details. A detailed view shows you a historical graph of how each round’s value has changed over time, remaining tickets by prize tier, and after-tax payout calculations (accounting for Korea’s 22% and 33% withholding rates).
- Maps nearby retailers. Can’t find a Speetto seller? The built-in map shows you every authorized retailer nearby, filterable by game denomination (500, 1,000, or 2,000 won), and includes one-tap directions via Naver Maps, Kakao Map, or Google Maps.
The app explains every metric in plain language—no jargon required. There’s a help section that breaks down what each indicator means. It supports both Korean and English, runs without requiring login or registration, and has no hidden purchases beyond optional ads. Location data stays on your device; it’s never sent to external servers.
Who This Is For
If you buy Speetto occasionally but never knew which round was smarter, this is for you. If you’ve ever realized after the fact that you bought a round where the top prize was already gone, you’ll find this frustrating-but-honest. And if you’re the type who likes to chase the statistical edge—waiting for that golden-window moment when supply is nearly exhausted but prizes remain—this app was built with you in mind. It’s made for anyone in Korea who wants real data instead of guesswork when making that quick stop at the convenience store.
This is not an official Donghang Lottery app, and it doesn’t sell tickets or process payments. It’s purely a statistical analysis tool based on publicly available data. It won’t guarantee you’ll win, but it’ll show you which odds are actually in your favor.
If you’re interested in trying it, you can find it now on the iOS App Store. It’s free to download with no required account—just open it and start comparing rounds.
