Type of Site: Mental Challenges
I found www.hackquest.de in Google. I like this site because it provides very difficult mental challenges that make you think and learn. As you solve each challenge you are given a password, which is used to add points to your ongoing score. (You must be at least 13 to register.)
The challenges are separated into categories. The easiest for beginners is the logic section, because you don’t really have to know much but math and logic. Some of these are word problems, others are just a series of numbers which can be used to arrive at a special number. Here’s the type of riddle or question you might find:
Seven people walk into a square room which has no windows.
They found a dead man who had clearly hung himself from the ceiling, but they couldn’t figure out how he did it.
There was no chair or table that he might of jumped off.
The only thing there was a puddle of water.
How did he do it?
Answer: He stood on a block of ice, which eventually melted.
There are forums for members to share ideas about each puzzle, but no one gives the answers, just hints. Some of the puzzles are really tricky, so if you’re a quitter don’t join Hackquest. The challenge selection screen shows you how many people have completed it, so you can see which ones are hard or easy. I get frustrated with many of the puzzles, but I love it when I solve one. If you like mental challenges, give it a try.
