** Codility Developer Training - Challenge Everything! **

The first 3 developers to solve the challenge perfectly in the least amount of time from the start of the challenge will be added to the Codility Hall of Fame and win a $20 Steam Gift Card. Whether you fancy more skins and items for your hero in your favorite game or want to play something new - we’ve got you covered.

Once the Gamer’s Challenge has ended (on December 4th), you will still be able to take the challenge and gain certificates, but you will no longer be in the running for prizes.

Good luck!!
