SpeedLotto: Korean Scratch

Before you buy, take a second to see today's most valuable scratch-off round.

Walk into a Korean convenience store for a Spitto scratch-off and you'll usually see 8 different rounds on display. The clerk grabs one at random, or you do. But each round is in a different state — different numbers of 1st-prize tickets still out there, different stock rate. Some rounds are statistically "above break-even right now," others have the top prize already claimed and are essentially empty shells.

This app pulls public data from the Korean DH Lottery and shows you every active round side by side, ranked by value.

■ What you see when you open the app

· Today's most valuable round — recommended at a glance
· Last-chance rounds — 95%+ stock rate but the 1st prize is still alive (the golden window)
· Rounds with the most 1st-prize tickets remaining
· Round detail — a value-change graph from launch to now, remaining 1st/2nd/3rd prizes, and after-tax winnings calculated for you

■ Want the technical details?

The round detail screen shows the remaining EV (payback rate) timeline, stock rate timeline, estimated sold rate (average payout of 3rd/4th/5th prizes), and after-tax winnings (22% / 33% Korean withholding). If any term feels unfamiliar, the in-app "Metric guide" walks through each one in a single line.

■ Who it's for

· Casual scratch-off buyers who didn't realize rounds vary in value
· Anyone who's bought a round whose top prize was already gone
· Last-chance hunters tracking late rounds with the 1st prize still alive
· Available in both Korean and English

■ Things to know

No signup or login required. Beyond ads, there's nothing to pay for. Location permission is only used on the retailers map and is never sent off-device.

Data is sourced from the DH Lottery official site (dhlottery.co.kr) — public round, prize, and remaining-ticket information.

This is not the official DH Lottery app — it's a third-party statistical tool built on public data. A round being recommended does not guarantee a win. Lottery purchases by anyone under 19 are illegal in Korea. For gambling addiction support in Korea, call 1336.
