Monty Hall has cloned himself, and his 40 clones have hidden themselves behind 40 doors! Unfortunately, something went terribly wrong with the cloning process and Original Monty needs your help to round up his clones and provide them with clone rejuvination serum.
When you click on a door, a second door will open, revealing a goat. Goats are inherently drawn towards Monty Hall; a door with a goat behind it means that there is at least one Monty Hall behind one of the eight ajacent doors. Two doors will become highlighted in yellow: the door you originally selected, and a door next to the door that was just opened. Click on one of the two yellow doors to choose which one you believe has the Monty behind it. Exactly one of the two doors is always correct!
If you open a door with a Monty Hall clone behind it, Original Monty gives him the serum and you score a point! If you choose the other door, however, the clone escapes, and begins aging rapidly. Save as many Monties as you can!
