Durebak — lottery games and everyday calculators

Durebak is the Korean word for the bucket you lower into a well. It doesn't make the water; it brings up what is already down there. The screens here are that kind of tool. Pick lottery numbers, count the days to a date, convert a unit. If it's something you'd search for, use once and close, it goes here.

What's here

Games. Korea Lotto 6/45 and US Powerball. Pick a set, save it, and once the draw is out you'll see how many numbers matched. There are past-draw and number-frequency pages, a simulator you can run over a long stretch with your own settings, and a weekly set picked in advance each week (Korean only).

Tools. A character counter, a Korean age calculator, a D-day counter, and a dp ↔ px converter. Each one states the rule it counts by, right on its own screen.

Game rules sources

Game rules were verified against official, trusted sources: Korea Lotto 6/45 via Dhlottery, and Powerball via the official Powerball site. This Service is not affiliated with lottery sales or brokerage.

Winning data sources

The Korea Lotto 6/45 winning numbers used in Past draws, Statistics and the Simulator follow the official Dong-Haeng Lottery draw results, retrieved through a public mirror dataset (smok95/lotto). Draw numbers, balls and prize amounts are used exactly as officially published.

The Powerball winning numbers used in Past draws and Statistics follow New York State Gaming Commission open data, retrieved through NY Open Data (data.ny.gov) for draws from October 7, 2015, when the number format changed. The open data carries no prize amounts or winner counts, so the Power Play multiplier is shown in their place; official results prevail. A few draws missing from the open data were filled in after checking other official sources.
