Code Review Gauntlet
Race the clock to spot planted bugs and security holes.
What it does
A timed bug-spotting game for practicing code review. Each round shows a realistic JavaScript, Python or SQL snippet with one to three planted mistakes, and you click the lines you would flag. Afterward you see what each bug was, why it happens and how to fix it, and false alarms cost you points. A daily challenge gives everyone the same round, and your profile tracks accuracy by category, streaks and best score.
Good to know
There is no shared leaderboard, so your history stays in your own browser.
