I have had so much fun playing with Polyhedron. Heres a question where all but one can build a 3D shape, but which one?

Nets 3D shapes

Mastermind

I have been playing Mastermind with my daughter. She likes the game but I wondered if I shared the game stages at the point I feel it could be solved, whether others could solve it earlier. These are two of our recent games.

This is harder to solve.
