New Xbox Live Arcade titles by the end of the month

This week in Major Nelson's blog the Xbox Live Arcade co-ordinater outlined the launch line-up for the month. Crystal Quest, Marble Blast Ultra, and Jewel Quest will all be out by the end of the month. Street Fighter II: Hyper Fighting, and Texas Hold'em will be out shortly after in late February. RoboBlitz, Feeding Frenzy, Hoop World, and Astro Pop are still waiting release date announcements. My question, what are Minesweeper Flags, Collateral Damage and Mugaki Blocks? (See the arcade titles in image) I found this screen shot HERE.
