About 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 chilleddev@gmail.com.

You do realize that you have to think it out, tell yourself what you think the answer is, then press answer to see if you're right. Right? Or are you just lazy?

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.

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!

Terrific

K70%

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 the internet. Everything is nicely organized too.

On crocodile sophism, saying that the crocodile will eat the child forces the crocodile to give back the child.

N70%
by N####:

Some of the options don't match the answer, like one said the answer was "minus" when the description of the answer said "decimal point - 5.9" which is a different choice that the app said was incorrect, besides that, great app

I'm glad you can access any question without solving any. It's a personal challenge, not a competition. However, some of the logic answers are severely flawed. I'm thinking of the honestants and swindlecants. In #6, there are two statements, not one. In #5, there is no way to tell because an if-then statement is only proven false if {p and not q}. Any other combination could be present when the if-then statement is true or false. These are good questions, though, even if the answers are rubbish.

This is just a list of questions and answers, not interactive at all

J70%
by J####:

You can try to think it out, but there's no place to input your answer. You just read the question and then read the answer. There's no challenge. Deleting.

H70%
by H####:

Flawed logic in the reasoning problem "stamps". There's no way to know what person B had because the grand master still has 2 stamps in his pocket. Persons A and C could both have had 1 green and 1 red stamp. Because there are still 4 stamps unknown to person B, he would only stand a 1 in 3 chance of guessing correctly. If the grand master had 2 green stamps in his pocket, person B could guess 2 reds on his forehead and be correct.
