Games
Five games that load instantly, need no account, and work offline once the page has opened. No progress to sync, no session to restore, nothing tracked about how you play.
They are here because a tools site should have somewhere to go when you have finished the task you came for.
- Android appChroma QuestMatch a colour from memory, pull real colours out of your camera, and race a friend over a QR code.
- 2048Slide tiles, merge matching numbers, reach 2048. Keyboard and swipe controls.
- Tic-Tac-ToePlay against a perfect AI, an easy AI, or a friend on the same screen.
- SudokuFresh puzzles at four difficulties, with pencil notes, hints and mistake checking.
- Memory MatchThe classic concentration game in four sizes, with move and accuracy tracking.
- Typing Speed TestMeasure your WPM and accuracy over 15, 30 or 60 seconds. Live feedback as you type.
Why these run in your browser
With one exception on this page: Chroma Quest is an Android app rather than a browser game, because its camera mode needs a camera. If you want the browser version of the same idea, the colour perception test runs here with no install.
Every page in this section is a static HTML file plus a small JavaScript file. There is no backend, no database and no upload endpoint. When you open an image, a PDF or a spreadsheet here, the file is read by your browser's own File API and stays in the memory of that tab until you close it.
That is a deliberate architectural choice with real consequences. It means we could not look at your files even if we wanted to, it means there are no queues or daily limits, and it means the tools keep working on a plane or a train with no signal. The trade-off is that anything genuinely requiring a server — live exchange rates, for instance — is the exception rather than the rule, and we say so on the page where it applies.
