What are your favorite casual games?

[radioioRobert]

Though casual games take a lot of abuse here in the forums, and in the gaming press & online community, we all play some of them. What are your favorite casual games (and for which console, handheld, or pc)? Are there casual games you don't play that you think are well done (a good example of this for me would be Order Up)?

My favorite casual games:

Tetris (Multi, I have NES(Tengen), GB, DS, Wiiware)

Pinballs Greatest Hits : The Williams Collection (Wii)(Psp version is ok too, but the Wii Controls make it)

Luxor (Multi)

Peggle (PC)

Wii Sports (Wii)

Buzz (Assorted Titles, PS Family)

Dr Mario (NES/VC/GBA)

Guitar Hero/Rock Band (Multi)

Ultimate Brain Games (GBA)

Bejeweled (Multi)

Zack & Wiki (Wii) (added)

Lumines (PS Family)(Added)

I think the following are well done casual games:

Nintendogs (DS)

Scene It (360)

Singstar (PS Family)

Karaoke Revolution (Multi)

DDR (Multi)

Diner Dash (PC/DS) 

That's just off the top of my head, there are a ton of well made casual titles. Discuss.....
