- Korean office workers seeking quick tools or games
- Worth noticing
- The salary comparison uses a 2025 Statistics Korea survey; when a group is too small, it broadens the comparison and says so.
Field notes
The salary comparison is based on the August 2025 supplementary survey on employment types, for regular employees, and uses age, gender, and occupation to select a comparison group. The lottery section includes historical results, regional winner counts adjusted for the number of sales outlets, and a display comparing apparent hot/cold number gaps with expected random variation. The maker describes the site as a personal hobby project.
