Puzzle electronic games for 8 year old

[toughday]

I am looking for a gift for 8 year old ds, he loves puzzles, maths memory games etc. I remember having these kinds of handheld electronic games as a child but I can't seem to find anything!!
He never asks for much and for Christmas has just. asked for a surprise. Thanks

how about a ds? you can get all sorts of games for them

He has an iPad and his sister has a DS which he will use time to time. I think I'm looking for something more retro.
Having a look around Amazon last night I came accross bop it or Simon game. Might have to actually brave the shops sometime and see what is out there!!
