How do you get on brainiacs on game show island?

Answer 1

To get the entry ticket, you have to help a robot find the correct colors for the windows that signal landing aircraft at Moscow.

The straightforward method (4 tries) is just to try all blue on the bottom row, then change the wrong windows to yellow on the second row. On the third row, change any that you don't know are blue or yellow to purple. Any that you still don't know by the fourth row must be orange.

Then there is the "out of the box" solution:

- turn all the windows blue on the first level,

- turn all the windows yellow on the second level,

- turn all the windows purple on the third level,

- turn all the windows orange on the fourth level.

Now you know the exact color for each of the 4 windows by looking at the (green) indicators on those four levels. Turn them the right color on the fifth try.
