Libble Rabble

The player controls two "arrows", one red (Libble) and one blue (Rabble) with a line strung between them. The object is to wrap the line around poles and surround Mushlins and enemies with it. The player can either close the loops themselves (worth more points for the Mushlins) or move both arrows to the same edge of the screen. The player clears a "season" when they harvest all the Mushlins.

Along the way, various enemies will appear and try to stop the player. The most common are four little hooded critters (Hobblins), which start each season in the corners. If the player catches enemies in a loop, they will be sent to the top of the screen for a short period of time. Other critters such as fireballs (Killers), sparks (Changers), and Demons will also appear.

Libble Rabble was designed by Tōru Iwatani, best known for creating the arcade game Pac-Man. Iwatani conceptualized the game based on an experience he had in a crowded disco hall in the early 1980s, where he envisioned himself using ropes to tie people up and throwing them out of the way. It was also inspired by a game that he played during his childhood, which involved tying ropes around short metal poles stuck in the ground. Early versions of the game were known as Potato due to Namco considering the game be a tie-in with a Japanese potato chip manufacturer, but these plans fell short as the company was unable to get the license. Due to the game's size and graphical effects, a new arcade board named the Namco Libble Rabble was created to fulfill these conditions, designed by hardware engineer Toru Ogawa.

Midway through development, Iwatani soon grew overwhelmed with other projects, passing duties off to designer Seiichi Sato. After seeing the prototype build, Sato found the game to be too simplistic and decided to incorporate new ideas to try to add a layer of strategy to it. One of these was the concept for treasure chests and uncovering them, an idea influenced by the Apple II role-playing game Wizardry. Music was composed by Nobuyuki Ohnogi.

Libble Rabble was a successful game in Japan. Game Machine listed the game on their January 15, 1984 issue as being the second most-successful new table arcade unit of the month. Japanese publication Amusement Life applauded its unique twin-stick controls and interesting gameplay, saying that it made it stick out from other games in arcades at the time. Reviewing the Super Famicom home conversion, Video Games magazine referred to it as a "politically-correct Super Bomberman", noting of its unique yet strange premise. In a retrospective review, Retro Gamer magazine stated that it was a "true, underappreciated classic" of the puzzle game genre, favorably comparing it to Taito's Qix.

In Battle City, also by Namco, one of the maps resembles a Hobblin. A remix of the game's theme is featured when the player zooms in on a museum product in Namco Museum Vol. 4's museum mode. The game's theme was used in one of the levels of the Pac-Man Vs.
