Non-violent Puzzle Games

Can you guys name me some non-violent puzzle games that kids of a younger generation have ease to play?

I can only think of World of Goo and Machinarium. Maybe Portal 1 & 2 but I think the gameplay is too advanced for kids (<10 years) and the use of English language which my younger brothers do not understand.

Please post any games that comes to mind :)

standalone games or browser flash based?

Anything. Indie, Free-to-Play, upcoming, old-school ect.

Post 'em and I'll check it out :)

Perspective is a great one.

Yes, Logan talked about this one in a Tek episode. Mindblowing. Free to play? Seriously?!

Please check out my reccomandations:

I loved Wik - The fable of souls and Boulder Dash Treasure Pleasure when I was littler, they're great.

Also try the classics : Tetris, Sokoban, Grim Fandango, Beyond Good & Evil, Siberia, THE INCREDIBLE MACHINE (was named all caps, also it's the best, try Crazy Machines, they are 3D (but 2d perspective) and have the same gameplay, I liked them all, didn't try the newest one though, which let's you see in other perspectives).

I dislike the Zuma/angry birds/drawing spam of games that use the same mechanics. Crayon Physics was cool though.

I enjoyed this one: http://www.flaminglunchbox.net/curvy

Gears and Cogs are two fun puzzle games I think <10 could play.
