Same editor, same time travel. What changes is what your code turns into on stage.

Code Duel

Real code

One data problem, two players. Your operation count is measured on growing inputs: O(n) tears down the O(n²) castle. An asynchronous race against a rival's verified solution.

Code Reading

Reading

Understand code without writing it: hunt the bug, predict the output, review AI solutions, read the Big-O. The skill interviews and code reviews lean on most.

Database

SQL

Write queries against a real SQL database: solve a data leak with door logs, file access and VPN logins. Your query is tried on hidden datasets too.

HTML/CSS

Draw the target exactly with HTML and CSS. Your drawing sits live over the target and the pixels that differ light up red.

Terminal & Git

Shell · Git

Type commands in a real shell: files, pipes, grep; then branches, merges and conflicts with Git. The commit graph draws live and every step can be rewound.
