Groovin' Blocks

Groovin' Blocks is a falling block-type puzzle game with gameplay that has been likened to Columns and Lumines. The game sees players having to clear lines of three or more blocks of the same color, and like Columns players can cycle through the falling lines of blocks, with adjacent blocks of the same color also disappearing with the matched lines. In addition, extra points can be scored when players bring their falling blocks down to the downbeats (called "Superbeats") of the game's electronica soundtrack, adding to a score multiplier.
