Mission: T.H.I.N.K.

In Mission T.H.I.N.K. (Thinking Hard Inspires New Knowledge) Morty Maxwell tries to take over the Shady Glen Game Factory with help of the Metal Minions with the player competing over a number of levels to stop them.
Players must complete five levels to finish the game. The levels themselves are identical to the ones featured in an earlier game, Gizmos & Gadgets!. Each level involves going through a warehouse, solving puzzles to open doors, and collecting pieces that must be used to win a checkers-like strategy game at the end of the level. While exploring the warehouse, the player must avoid having their pieces stolen by the Metal Minions. A magnet can be thrown to trap a Metal Minion and reclaim a stolen piece - the magnets themselves can be used an infinite number of times. After beating Morty at all five levels, a puzzle is put together portraying him leaving the factory.
