Denki Blocks

Players manoeuvre blocks (called "Gumblocks") around a board also consisting of "blockers", which never move. A move is a single step in one of the cardinal directions, which is applied simultaneously to all Gumblocks that are not blocked. When Gumblocks of the same colour collide, they merge into one (called "clumps"). The main objectives are either to join Gumblocks of the same colour, or to join Gumblocks of a certain colour into a specific shape.

The last move can be reverted, and games can be restarted at any time. Some puzzles feature bonus shapes or a "Three Of A Kind" (three clumps of different colours but the same shape) which earn "Denki Stars" if made. Denki Stars can be spent on special puzzles in the "Denki Blocks! Club".

Denki Blocks! was released on 18 October 2001 for the Game Boy Color (developed by Covert Operations) and Game Boy Advance. It was previously released on Open Games (later Sky Gamestar) after Rage Games signed a deal with BSkyB. In late 2001, Majesco revealed that it would be publishing Rage games in the United States.

The game was published in the United States in late 2002. Denki's internal development manager Gary Penn said that Denki had a problem when they first made the game: they had wanted to do it in a particular way, but because it had to have a certain price, they eventually added many features. A Java version for mobile phones was released in 2002.

Denki Blocks! was well received. Reviewers particularly praised the gaily coloured graphics and the difficulty of the puzzles.

Craig Harris of IGN described the Game Boy Advance version of Denki Blocks! as "a lot of fun and one hell of a mind twister" and praised graphics and sound as bright and cheery, but wished that it supported console linking. com, Kyle Ackerman of Frictionless Insight, David Stockli of Gameswelt, and Justin Harkin of GameSpy. Its puzzles were described as "difficult" by Harris, as "ingeniously designed" by Edge, and as "cold and abstract" by Harkin.
