I'm basing my review primarily on the adventure game modes since they're the only ones I really had interest in playing. Peggle DS is pretty solid for a handheld experience, though of course not as impactful as the standard games. The two adventure modes, comprised of the original game and Nights, take you through five levels with each of the 10 masters, followed by a final set where you can pick which to use. Each master has their own ability you can use after hitting green bricks, and some of them are certainly better than others depending on the map. This ability gimmick adds a good twist that keeps the first adventure mode pretty diverse and Nights as well if you want the same thing again (there are no new masters in it). Out of all the levels, the ufo one in the first final set and the last level of the second final set are probably my picks for the hardest and most frustrating.

Overall, if you're looking for something to play casually on a handheld device this is certainly worth checking out.
