Shoutout to @ItsRoflz and their guide for Senior Varsity Puzzlete (Play 50 total matches in the Tournament of Puzzles). If you use their guide to help you towards 50 total matches, you'll get 10 (Junior Varsity Puzzlete) to pop along the way!

You spawn in a room with 3-4 trophies off the bat. To get to the next room, you need three keys. The next room has four trophies (enough to finish the game). My friend and I were able to get through games in around five minutes. Hit the box passively, as you may get lucky and be given a master key--which could shorten the game to under 3 minutes."
