About
A daily puzzle for people who read code for fun.
Stdle is a daily game in the spirit of Wordle, but for developers. Each day, every language gets one short, valid snippet. Your job: predict exactly what it prints.
Languages
Each language runs its own daily track with separate streaks and stats. Pick your language from the selector in the site header.

How to play
- You have 4 attempts to type the console output exactly.
- For multi-line output, separate lines with commas or new lines. A badge tells you how many lines to expect.
- We normalize whitespace and ignore matching surrounding quotes, so you can focus on the values, not formatting nitpicks. Casing matters.
- Each wrong guess reveals a hint. Hints start vague and get sharper.
- Solve it or run out of attempts, then see the answer and a short explanation of why the language behaves that way.
Scoring & streaks
- Your score for a day is how many attempts it took (1/4 is perfect).
- A streak counts consecutive days you played and solved. Miss a day or fail a puzzle and the streak resets.
- Stats (games played, win %, current and max streak, guess distribution) live in your browser — nothing is sent to a server.
- Share your result as a spoiler-free emoji grid, just like Wordle.
