The first two tournaments end in about 90 minutes so unless you can knock out two pages that fit the reqs in that amount of time, you won't be able to participate in those or win one of the three Grand Prizes (you have to complete all 8 tournaments on time to be eligible for one of the Grand Prizes).
You can enter the other 6 fournaments, though, and potentially win prizes for those tournaments. You can also still get all the participation prizes, including the SSD collab, after you register.
