Who runs Minigame Cafe
One individual operator in Japan builds and runs Minigame Cafe. This is what the operator shares about their background:
- Experience in development, infrastructure and maintenance at an IT company.
- More than 30 business-improvement systems built.
- More than 40 websites started and run by the operator.
You can judge the work on the game pages themselves. Most of them show their own counts and dates. “We” on this site means the operator.
Why the site exists
The idea is plain. Games should open in a browser and work without an account. You press play. We do not ask for an email address, and your records stay in your browser’s local storage on your own device.
A puzzle site also owes you puzzles that are fair. A Sudoku with two solutions, or a card deal that cannot be won, wastes your time. So in the games with a puzzle bank or a Daily puzzle, a program checks each puzzle before the site serves it. Two things are not checked this way: random Classic Minesweeper boards, and FreeCell deal numbers you type in yourself.
How the games are made and checked
We make the games ourselves.
- Sudoku: puzzles come from our own generator. Every puzzle in the bank of 2,500 has exactly one solution, and our solver finishes it with logic alone (checked 25 October 2026).
- Nonogram: every picture was drawn for this site, and a separate solver re-solves each one.
All games run in one shared page shell, and one common check script tests them for screen width, tap targets, keyboard focus, reduced motion, light and dark themes and saved records. When we cannot measure something, we leave the number out.
The methods, with dates and counts, are on How we test.
