The lite version of "Brain Challenge" !

Do you think you are intelligent ?
Let this application challenge you through different problems.
Enigmas, riddles, puzzles... Everything is here !
Even if you think that sometimes it is impossible, be sure that the solution is just under your eyes !

Your brain is going to have a hard time, I promise !

Try out the 10 first levels with this version for free now !

Just one thing, please, do not write directly the answers in the comments. If you want to help, just give hints, thank you.

Note :
I noticed on comments than some people could not solve problems on really early stages (level 2/3), and I understand this can be frustrating, so I just added a forum for people who are stuck on a level to be able to get some hints.
Hope this is going to help people.
