Is anyone else watching this?
Each week, the contestants are given a challenge. They have 30 minutes to (individually) design a possible solution and present their solutions to the judges. Based on those solutions, the two judges assign first and second place, and those folks then choose their teams.
Each team then gets a specific amount of time (like "3 days") and money (really varies) to build their solution.
At the end of the challenge, the teams test their results. The judges determine which team won, and then they choose which person on the team is leaving (after getting input from the other team members).
The person who leaves actually joins the "Wild Card Challenge". These folks are chosen during the following weeks to work on a team, so the teams always have the same number of members (at least at this point). At some point, there will be a challenge for just the folks on the Wild Card "team" to decide who gets to re-enter the game.
We didn't agree with who they sent home the second week, but it's interesting seeing the groups try to work together.
