A few useful things to know.
Do I need to be a teacher to host?
No. A verified account can host a class, tutoring session, or study group. One person runs the session and reviews the answers.
How do points and damage work?
Correct answers deal 100, 150, or 250 base damage for easy, medium, or hard problems. Points use the same base plus a speed bonus: 50 for the first correct answer, 40 for the second, down to 0. Optional surprise events can add bonuses. Every correct team contributes to the shared challenge.
Do students have to create accounts or pay?
No. Teams join using the session code. Use one device per team; the session host chooses how many people are on each team.
Do I need a projector?
No. You can share the display in a video call, put it on another screen, or write a problem on a whiteboard. For PDF projection, choose the physical page number—the first page in the file is page 1, even when the printed page says something different.
Can I edit an answer after submitting?
No. Discuss and check your answer before submitting it. Wait for the received confirmation before leaving the page. If your connection drops, the app keeps your draft in that tab and lets you retry; it never sends an answer automatically while offline.
What if I choose the wrong team?
Leave the session and choose again. A host can release a team’s device from Teams & invites. Existing scores and answers stay with that team.
Can I use it as an app?
Use your browser’s Install app or Add to Home Screen option when available. Live sessions require internet access. Native Android and iOS apps are a future phase.
