How can we help?

Running one tied to a League and claiming it pays up to 1,500 XP for an interview and up to 1,000 XP for an assessment, scaling with your score (350/250 as a floor, the rest based on how well you did). You need more than 5% lesson progress in that League first, and there are weekly and monthly limits to keep it fair -- see the full guide for the exact numbers.

For Students

No - it is a Pro-only benefit. Pro members get one spin every 7 days for 5-15 bonus coins or a 10-15% discount coupon.

For Students

Yes. Python, JavaScript and TypeScript run instantly in your own browser when you hit Run, so you get immediate feedback on the example tests. Submit always sends your solution to the judge against the hidden tests.

For Students

Yes - switch to the Database tab for 60+ SQL problems with a real dataset. You can write queries in MySQL syntax (backticks, LIMIT a,b, IFNULL, date functions) and they still run correctly against the judge.

For Students

No - the daily, weekly and monthly problems and the practice library are free for everyone. Pro adds the full problem archive, every hint and editorial, an AI coach, and priority judging when the queue is busy.

For Students

You get a catch-up window to solve it late for half the normal reward - 3 days on the free plan, 7 days on Pro (which also gets a 7-day catch-up on weekly and monthly problems). A late solve never counts for the streak bonus.

For Students

It depends on difficulty and type. Daily problems pay 10-60 XP and 5-20 Aura; weekly pay 15-80 XP and 10-25 Aura; monthly pay 100-150 XP and 35-50 Aura. Practice-library problems pay 10-30 XP only, no Aura. Pro members get +10% Aura on every solve.

For Students

A free coding practice ground: a new problem every day, a harder set every week, one big challenge every month, plus a 400+ problem practice library covering arrays, strings, hash maps, SQL and more. Solving pays XP and Aura, with hidden tests across 14 languages.
