octree.io

octree.io is a platform where you can practice Leetcode-style problems in a room with other people. It serves as a supplement to Leetcode as you can invite your friends to practice problems together. It features a Game Room, Trivia Room and a Lobby which is a Slack-like chat room. The Game Rooms are the algorithm problem rooms where you can practice with other people. A timer appears on the screen and your objective is to complete the problem before the timer runs out. The Trivia Rooms are where you can create a question bank and load any set of questions into the room. You're given 2 hours to answer all questions that were loaded from the question bank and at the end your results will be graded by AI.
