Timewasting puzzle mind games

[Top]

Hi.
I'm looking for some small online games where you have to figure out the right solution/combination before moving on to the next level.
Probably not the best description, but hopefully you get the idea.

Here's some examples of games I've enjoyed when bored:

If you got some games like this then please share.

I'm also trying to remember another game where you had to guide a small man over to a destination by clicking on various obstacles which would then tricker something else and thereby making his path clear. It was pretty difficult. You could fx. click on a bird making it drop an egg in a bucket which would then open a door or something like that.
There was 3 versions of this game when I last checked but I can't remember the name of the game.

here's the best of the lot:

goggle 'impossible quiz 2' and attempt that. i found it fun, addictive, challenging, annoying all at once. there's the impossible quiz 1 but i prefer the second. if you need to know the answer, search for the same thing on youtube. they have vidoes of ppl completing the quiz. try it.
