A new code puzzle every day. Guess the language, find the bug, climb the leaderboard and keep your streak alive. Built for developers and the code-curious.
Can you tell Rust from Go by a single snippet? Spot the bug before it ships?
Syntaxle is a daily puzzle game for programmers. Every day there's a new code snippet. Guess which language it's written in, or on some days, find the error hiding in it.
DAILY PUZZLE
You get six guesses. After each guess, five clues tell you how close you are:
• Year released (higher or lower)
• Country of origin
• Object-oriented or not
• Static or dynamic typing
• Compiled or interpreted
Over 45 languages, from Assembly and COBOL to Rust, Kotlin and Elixir.
FIND THE ERROR
Some days bring a bug hunt instead. Read the snippet and pick the real error. You only get one try.
CODE QUEST
Work through five themed levels, from Boot Camp to Expert Mode, at your own pace.
SPEED RUN
Name as many languages as you can against the clock and chase your personal best.
LEVEL UP
