Denki Blocks In Denki Blocks, players are given the task of linking same-colored blocks to one another by sliding the entire playfield of colored blocks. All of the blocks will slide in unison unless they're stopped by A) one of the four edges of the playscreen, B) Other blocks of different colors, or C) Dead, stationary blocks. It's up to the player to utilize the edges, other colors, and stationary blocks to maneuver the blocks around each other. The goal is to solidify all the colors by linking like-colors together.
