How team selection works
- •Only one person (team lead) fills the team form. Teammates are added by their email address.
- •If your teammate has already added you to their team, this screen will update automatically — you don't need to do anything.
- •Each teammate must have their own account (they need to register with their email first).
- ⚠️Once confirmed, teams cannot be changed. Solo is locked for Round 1 only.
Solo Warrior
Compete individually. You'll work and submit on your own.
Team Up
2–3 members. Only the team lead fills this form.
