What are Hackos?

Hackos are HackerRank currency you can earn and spend on the site.

How do I get Hackos?

When you register on HackerRank, you are immediately awarded with 100 Hackos. As you continue to solve more challenges, you earn more Hackos. Please keep in mind the amount of Hackos earned is not based on the score or points awarded for a challenge. The amount of Hackos that you earn on solving a problem depends on the Level of the challenge ( ie. a difficulty level of Easy for a challenge will let you earn 5 points), and is shown below:

All challenges solved till now would be marked as Practice.

You also earn Hackos for maintaining a login streak, where a streak of 1 day grants you 1 Hackos, 2 days grant you 2 Hackos, and so on, with an upper limit of 10 Hackos.

Where can I use Hackos?

You can currently use Hackos to buy test cases. Each test case costs 5 Hackos. So if your total Hackos count is 40, and you buy 2 test cases, your total Hackos count will become 30.

Is that all?

Currently yes, but we will soon be adding more ways to earn and spend Hackos.
