The Island of Dr. Brain/Control room

Control Room
Once in the control room, you will be prompted to press the button. Once you do, a panel will begin smoking. Click the panel to access the Navigation Computer

Navigation Computer
This is a pattern puzzle. You have 4 rows of tiles, and each row is missing one piece. Look at the other tiles in the row to determine what the patterns are (color shape, size, text), and complete the row using the correct tile from the spare tiles on the right. Once all 4 rows are completed, the panel begins an animation and the puzzle is solved.

Transistor Logic Puzzle
Push the lever forward, and there is another malfunction. The old computer chip must be tested and replaced. Test the old chip to determine the binary logic sequence, then reprogram a new chip with the same code. In Novice mode, this is nothing more than trying any of the gates at random if you don't understand the puzzle.

For Standard and Expert modes, you must understand Boolean Logic to solve the puzzle and create a string of 8 or 16 binary values (0 or 1). The required solution is shown in the red 0 column, and your solution is shown in the blue 0 column.

You are provided with several columns of truth tables (A, B, C, and D), and using the logic gates of AND, NAND, OR, NOR, XOR, XNOR, and NOT, you must combine the columns and operators to generate a string of numbers. You may not use all of the columns A-D in your solution, and your solution may require 0, 1, 2, or 3 gates.

Complete
Once you have solved the logic puzzle, throw the lever forward and the game is complete. Watch the final animation and credits.
