The kind similar to Pogo's Poppit (as seen here) where you'll line up colors and then eliminate them. I know these types of games get cloned often, so chances are there's at least one or two available for DS. I am aware there is a Pogo Island release, but I'm trying to _buy_ the game as opposed to downloading it. And tracking down a reasonably priced copy of Pogo seems near impossible. The link on their official site to the EA store doesn't even work--they don't appear to sell it. Everything on Amazon is absurdly expensive, like $30+ for used.
