Honeycomb Beat review at PALGN.

"Some of the DS’ most popular puzzle games have had addictive, yet simple gameplay. Tetris DS obviously only has players create lines by rotating shapes while Meteos, has players ‘launch’ blocks into space. While Hudson’s Honeycomb Beat follows this formula, it unfortunately doesn’t have the same depth.

Honeycomb Beat’s concept is quite clever. Essentially, there is grid of hexagonal tiles that have a different colour on each side. Using the stylus, you need to flip (or ‘beat’) each tile so that they are the same colour. The game’s challenge comes from the connection between each tile – when you beat a tile, all the surrounding tiles will also flip, changing their colours in the process. Because of this, often you’ll be left with a single tile that is the wrong colour, so the emphasis is on planning out which tiles you should flip and in what order. Additionally, there are special tiles called vector labels that will either flip all the tiles in a particular row, or only flip a single tile."
