Island of Dr. Brain was quite the puzzle-fest, and of course, for a puzzle-lover like me, it was fun to play. However, I suspect that the parts don't add up quite the same way they did for its predecessor. Let's see how the categories compare.
Puzzles and Solvability
Puzzles! Definitely! But, like Castle, they're all individual mental puzzles, several of them classic by this point, like Towers of Hanoi. Others include math puzzles, word searches and other word puzzles, jigsaws, programming, even music and art. They run the gamut of school subjects, in fact, and many of them are quite a bit more intellectual than the puzzles in Castle.
