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?

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 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.

    Doesn't even work, it says there are no brain teasers. Even if I search or pick a random category.

    I've downloaded about 10 different puzzle/riddle apps and this is probably the best. Has all of the classics and a lot of new takes that I haven't seen before as well as useful summaries of how to get the answer for a lot of questions (most apps just give you the answer and no explanation as to why). It's clear the authors know their stuff and haven't just copy and pasted riddles and answers off
