This page is dedicated to the Sierra game The Island of Dr Brain, and still under construction. A Castle page is coming up.
This game is built in a walkthrough section, which describes the paths between puzzles, and a puzzle section, which tries to help with the puzzles on all 3 levels.
First of all, prepare yourself before playing the game. If you don't have adequate manual help, get a Periodic Table of the Elements (Mendelev Table), an encyclopedia, a dictionary, atlas, calculator, paper and pen. Secondly, remember the regular cheat: save around it. When you fail to solve a puzzle, leave it, save, play again, use hint watch, restore, and complete the puzzle without using hints.
At the start of the game, you have to bypass the copyright protection. You should find it in your manual. Enter the correct data that fits the symbol the program shows you.
There's no bypassing this scene. You will have to do this every time you start up the game, even if you just restore an old game. Even though you'll always do this at novice level, you get a Gold Plaque.
You receive a Plaque for every puzzle you solve. Bronze for Novice, gold for expert level. A bronze plaque gets you 1 point, a gold one 3. You also earn points if you have hints left, the more you have, the more points you get. You can also get Extra Credit if you solve a puzzle several times. The total amount of possible points is 1000. To reach this score, every puzzle must be completed 4 times in each difficulty level. For the word search, that means you have to solve 4 puzzles per difficulty level per language: 36 word searches in total. There is a small bonus involved if you complete it with 1000 points.
After landing on the island, you end in front of a wall. Click on the pieces in front of it to play the Shape Manipulation Puzzle.
In the room, press the red button on the table to turn on the monitor. Use the monitor to play the Algebra Puzzle. Click the receipt on the slot in the coffin. Solve the Logic Math puzzle. Click the disks on the poles on the table to the right. Solve the Towers of Hanoi. Then leave the room through the door you just opened.
First solve the jigsaw. Click a flamingo to start the Logic Pattern puzzle. Then click the sign for the Foreign Language Word Search.
Click the sign by the cliff for the Code Puzzle. Click the Botanic sign for the Animal Spot Puzzle. Click the basket with items on the door to the volcano for the Chemical Analysis puzzle.
Click the table near you to play the Magic Square Puzzle. Then open the door for the Spectrum Analysis puzzle.
In the next section, the Synonym (apple trees), Homonym (corn) and Antonym (ant hill) puzzles may be solved in random order. Whenever you solve a puzzle, click the apples/corn/watermelon on the scale at the end of the path. After all 3 items are placed on the scale, enter the hut.
In the hut, click the PC to play the Visual Pairing puzzle. Then click the key on the bookshelf for some General Knowledge puzzle.
In the next room, click on the cup section for the Liquid Weights puzzle. Then enter the elevator for the Physics Puzzle.
Then enter the Robot Room. Click any of the pink/yellow/green chips on the right into the back of the robot head, then click the PC to program the robot. Get one item at a time. Then, click the genetic tube on the circle in the table to the right and solve the Genetics Puzzle.
In the next room, click the panel for the Art Recognition Puzzle. Then click the organ for the Music Theory Puzzle.
Enter the final room. Push the button for the Logic Pattern Puzzle. Push the lever forward. Click on the machinery that just broke and remove the sparking plug. Click it on the PC for the Logic Gates puzzle. Then wait a little, pull the lever, and you've finished the game!
Here I attempt to push you into the right direction. Most of the puzzles are random, so an exact solution is not possible. Remember you can change difficulty at any time, in case a puzzle proves too much for you.
Entering the wall
Unfortunately, this one is both random and impossible to hint for. The biggest aid I can give you, is to not give up and make sure you don't leave any small gaps. If you ask for hints, keep a 6*8 square notice paper at hand.
Algebra bacteria This one is manageable at novice level, at expert level it may get you more difficulty. First, set the blue, straight line to part the blue (and green, if there is any) section. On Expert level, you need to fit the parabole in the right place. Remember the following rules for the lines:
y = ax + b
Jigsaw: Right-click any time to see the full picture. Remember the larger sections: the boat, the rocks, palm tree, wheel, the dressed flamingos, and the floating giraffe. Use the edges. Listen to the click when you put down a piece: there is a different click for one that is, and for one that isn't in the right location.
Logic Sequence Flamingos: Note which are flashing, and in which colour they flash. Write down which flamingo causes which birds change into which colours. You can always solve this puzzle, no matter how much you change the birds. On Expert level, there is a bird that flashes blue, one green, one purple. Try all the flamingos. You can find 2 that control the "blue" and "green" flamingo exclusively. There is also one that turns 4 flamingos into purple, and changes 3 back into red, leaving the one that should be purple in the destination colour.
Language WordSearch: As with most word searches, begin by looking at the less-frequent letters and other symbols. Blank spaces, ñ, ë, è, ï, é... In German, Z is useful. Also, look at double letters.
Note: There's some bugs here. You may have a double word in the list, and if you find them both, only one may be ticked. There are 2 workarounds: use the Hint Watch if you have only this word left, or click Exit and make a new puzzle.
At times the puzzle may not load at all, and you'll have to restart. And some of the words have REAL ODD translations...
Code Puzzle: There are 2 to 3 different techniques for mixing the words: Letter Swap, Insert/Delete Spaces, Word Swap. The word with the dot usually goes at the end, the word with the capital goes at the start. Note a quote may also contain names or I, or may consists of 2 or more phrases.
All quotes can be found in this printable text file: Quotes
Magic Square: First of all, note the Goal button. Click it to change the total squares so they show how much you still need in the row/column/diagonal, not how much you need in total. You will have to use some numbers more than once. If you have troubles, try to make as many rows and columns and diagonals as possible correct. Then double-check the numbers and see if you can tweek some up and down. Otherwise, just save and get a hint.
Spectrum Analysis Just try them all once. The Expert level is actually the easiest one: just figure out which 2 elements don't match the spectrum, then throw the other 6 on the fire.
LANGUAGE PUZZLE BUG: If you have to use the Hint Watch, you may find a thick black stripe through the puzzle and discover it's not responding. Haven't found the cure or the work-around. Don't use it! A dictionary is easier.
Antonym Hill: In the quotes, look for a word that means the opposite. Some of the words chosen are pretty unfortunate. All quotes can be found in this printable document: ANTONYM
Synonym Puzzle: Nice! Shakespeare! You may use some queerly abbreviated words, and you may have trouble with words that aren't used in a certain context anymore.
Printable list of Shakespeare quotations: SYNONYM
Liquid Weights: This puzzle is dreadful, as it calls for knowledge that is nowadays not part of European knowledge. It is also not found in most sources I looked in. So, I'll list it for you in a table:
|Cup||0 lb 8 oz||7 lb 1 oz (112 oz)||0 lb 6 oz|
|Quart||2 lb 0 oz (32 oz)||28 lb 4 oz(448 oz)||1 lb 8 oz (24 oz)|
|Gallon||8 lb 0 oz (128 oz)||Don't try! (1792 oz)||6 lb 0 oz (96 oz)|
Next comes the Art Concentration. The 6 painters have luckily very different styles. Still I found it hard to tell some Pollocks from Kandinsky, so I slapped together this nicety for your recognition pleasure:
Programming: The pink chip will function properly. If you use the yellow chip, take note while you program. If there's a bug symbol in the line, program the OPPOSITE action: pick up if you want to drop, turn left if you want to turn right, forward if you want to go backward. The green chip functions normally... until it faces a monitor, then it stops.
Remember that, unlike on Castle, the robot needs to turn and walk forward, not just MOVE LEFT or MOVE RIGHT. On Expert, use the proper chip for a distant crate, and don't steer the green chip into a monitor.
Genetics: Create the Ideal Cyborg.
There's a nifty Genetics card in this room that will tell you all you need.
The ideal you'll have to create, has 10 letters: let's say BbAaEeMmLl. In every pair, the first letter (in this case B, A, E, M, L) comes from paternal (left) side, the second (in this case b, a, e, m, l) comes from maternal (right) side. On Standard and Expert, when you create the father, look for a male of which all of the first letters correspond. You may use any female if you find a good male, but if the male is lacking (eg has ll) look for a female that complements him (with LL). Do the same om maternal side, look for a good mother and a father who complements if necessary. Then breed, check the right offspring in the generation, and huzzah!
Logic Pattern: Click on the symbol that fits logically in the blank. The difficulty level of this is primarily in the question itself: some symbols are much easier to read than others. The Save/Hint system is the only other advice I can give you.
Logic Gates: After testing the chip, find the right logic gates that will produce the outcome. After testing the old chip, study the table. Try to discover a logic pattern between input and output. Remember not all the input (A B, C or D) may be used.
