What is ScramboCSS?
ScramboCSS is a browser-based CSS unscramble game for frontend developers and learners. Each run gives you 10 levels built from real CSS terms, including properties, selectors, at-rules, pseudo-classes, pseudo-elements, functions, keywords, and modern CSS features.
How a run works
- Watch the tiles land.The timer starts after the falling letter animation finishes, so you are not punished during setup.
- Type the real CSS feature.Answers are case-forgiving, but required symbols still count.
- Score with speed.Each level can last up to 60 seconds. Faster solves earn more points.
- Finish 10 levels.At the end, you get a score report, review breakdown, share options, and leaderboard links.
Symbols matter
ScramboCSS is built for real CSS syntax, so symbols are not decoration. @media, :has(), ::before, color-mix(), and grid-template-columns must be typed with their syntax intact.
Tips for better scores
- Look for punctuation first. It often tells you whether the answer is an at-rule, selector, or function.
- Use the one reshuffle charge only when the tile order is slowing you down.
- Keep an eye on the feature tag. It gives the category, length, and difficulty without revealing the answer.
- Replay to learn patterns. CSS terms become easier to recognize after a few runs.
