Brain Teasers

Brain Teasers


This application is a set of logic, math, geometry, number, matchstick and other types of brain teasers that require logical thinking.

All the puzzles and riddles are available in English, Russian, Chinese, Czech and Slovak language.

Sample brain teaser:
There are three switches downstairs. Each corresponds to one of the three light bulbs in the attic. You can turn the switches on and off and leave them in any position.
How would you identify which switch corresponds to which light bulb, if you are only allowed one trip upstairs?

Answer:
Keep the first bulb switched on for a few minutes. It gets warm, right? So all you have to do then is switch it off and switch another bulb on. Then walk into the room with bulbs, touch them and tell which one was switched on as the first one (the warm one). The others can be easily identified :-)

This and all other brain teasers and pictures are provided by http://brainden.com/puzzles-riddles.htm where you can find other puzzles as well.

Thank you all for your comments and suggestions which helped to add interactivity to the water brain teasers (pour water in several containers to achieve certain amount water in 1 specific container). More interactive games will be added shortly.

If you are interested in helping with translation into Spanish, your own language, or if you have any other suggestion to improve this app then don't hesitate to send me an email to [email protected]

I don't like most of the questions and I found a flaw in two of the questions. :'(

Good but... I found a flaw in an answer. I will not give any answers away but in the 1st water puzzle there is 2 ways of solving it. Also there isno place to put answers it is just questions and answers. Other than these flaws it is a great and challenging game!

Good but... I noticed an error in the answer options on Numbers puzzle #5. I won't give the answer away for those who don't want a spoiler, however. I don't yet know if there are others errors elsewhere.
