Google's longest-running coding competition, Code Jam, is back for its 19th season. Code Jam to I/O for Women is also returning for a ninth year, bringing together women programmers from around the world. In both competitions, developers tackle algorithmic challenges designed by Google engineers — all while building their network, sharpening their coding skills and even winning some prizes.

Code Jam returns April 1

At Code Jam, developers of all skill levels compete head to head in multiple online rounds. This season takes place from April to August, ending with a live streamed World Finals event. Competitors must earn enough points to advance to the next round. Out of thousands of participants, only the top 25 will head to the World Finals to compete for the title of World Champion and cash prizes of up to $15,000. And there will be plenty of other prizes to go around — the top 1,000 competitors will win an exclusive Code Jam 2022 t-shirt.

Code Jam registration is now open until the end of the Qualification Round on April 3 at 2:00 UTC — visit our schedule page to find your exact time zone. We recommend warming up with previous problems from the archive to improve your chances of advancing to Round 1.
