About this extension
Make every LeetCode submission feel like a game.

Choose one of 8 themes (Pixel Art, Grid, Paper, Web Crawler, Anime Studio, Adventure, Sakura Night and Orchid) and LeetCode is restyled instantly.

What you get: • Full screen verdict animations: Accepted becomes “TESTS CLEARED” or “LEVEL CLEAR!”, Wrong Answer becomes “GAME OVER” or “409 CONFLICT” • Sound effects for every verdict, all synthesised in your browser • A cartoon mascot who dances when you pass and cheers you up when you don’t • Particle effects and achievements as you solve

Free: 3 themes (Pixel Art, Grid, Paper) with verdict animations and sounds. MyTheme Studio Pro (₹49 one time): the other 5 themes and the mascot buddy. One key unlocks both MyTheme Studio extensions.

Private by design: no account, no analytics, no tracking. The extension never reads or sends your code or submissions.
