Tetris DS is an absolute must-have for that system. I can't tell ya how nice it is to be able to logon at 3am and play some kid in Korea who kick my ass in a matter of minutes. I'm actually pretty good at Tetris, but many of those kids can humble my ass in a heartbeat. It's seriously a lot of fun and probably the best Tetris game ever (so far). Puyo Pop is another good one, though it's more like Dr. Mario I'd say.

Same can be said about Mario Kart DS, easily the best version of the game ever released andthe unlockables rock.

I'm also a big fan of Metroid Prime Pinball. I know pinball doesn't sound like something that'd be a lot of fun in video game format, but I swear it is, and the dual-screen format really suits this game nicely. The multiplayer option only requires that one person have the game and up to 8 other people can play with you which is always nice. Also, I don't know of many other pinball games that allow you to actually fight bosses. Plus, you can usually find a copy for 10-15 bux so it's not gonna break your bank or anything. So yeah, get a copy cuz it's a fun game all around.

Last but not least, I had a lot of fun with the Electroplankton game. It's not even a game really, it's more like just this amusing music-making utility. Unfortunately, it's out of print and hard to come by, but if you can get a copy I'd say it's worth it.
