People love the challenge of a tough puzzle. Very few things are as satisfying as the feeling of accomplishment you get when you figure out a good puzzle. Well, maybe when you solve a really big real world problem or develop a new technology or even make a whole field of study or industry obsolete by creating a disruptive new technology, those are good too, but on this page we'll just stick to fairly tough puzzles. Both fascinating and frustrating, puzzles sharpen the mind and entertain the brain. Here, you will find Mental challenges and brain benders that at least appear solvable.
Here, you’ll find some of the mind boggling puzzles that have tortured us here at Stark Effects, and we’re happy to share them.
When credit for a puzzle is known, it is given. Unfortunately, we don’t always know the sources for our puzzles and we apologize for not having a proper reference for each.
