Phase blocks is a new take on the classic falling-block puzzle genre. All blocks must be phased before they can be cleared from the grid, and blocks are not cleared until their entire chain is phased. Player must merge phase arrows together (by dropping them on top of each other or merging in through the sides) to set off phase explosions, and can combo them together for huge screen-covering explosions. Score more points for clearing larger chains, but beware that chains become harder and harder to phase and clear the bigger they become. Read a design blog about it here.
