Kodigo

How to play

• Kodigo is Filipino slang for a cheat sheet, and you don't get one here. Pick HTML, CSS, PHP, SQL or Halo-halo (a bit of all four), then a level: Junior, Mid or Senior.
• Each round has 12 questions: multiple choice, "what does this code output?" and "spot the bug". After every answer you get a short explanation, so you learn something even when you miss.
• A right answer is worth 100 points. Keep a streak going for up to 50 bonus points, and in timed mode answer quickly for up to 50 more. If the clock runs out, it counts as a miss.
• Keyboard friendly: press 1 to 4 to answer and Enter for the next question.
• At the end you see how you did per topic and can review every question you missed. The quiz covers modern HTML, CSS (flexbox, grid, custom properties, :has(), container queries), PHP 8 and SQL. Your best scores stay in your own browser only.
