Puyo Pop Fever, known as Puyo Puyo Fever (ぷよぷよフィーバー, Puyo Puyo Fībā) in Japan, is the fifth installment in the popular Puyo Puyo puzzle game series, developed by Sonic Team, released on a wide variety of systems in several regions. Sega published all the Japanese versions of the game; the game was scarcely released internationally, and versions of it were released by other publishers. North America only received the Nintendo GameCube and DS versions, whereas Europe received all domestic and major handheld versions. Sonic Team acquired the rights to develop the series from former publisher Compile, after they went bankrupt prior to the release of Sonic Team's first Puyo Puyo game Puyo Pop. The NAOMI port to Dreamcast was the last Dreamcast game developed by Sonic Team.

Puzzle Bobble 4 (also known as Bust-a-Move 4 in North America and Europe) is the third sequel to the video game Puzzle Bobble and is the final appearance of the series on the Arcade, PlayStation and Dreamcast. The game is also the final title to be recognizably similar in presentation to the original. Building upon the success of Puzzle Bobble 3, the game adds a pulley system that requires two sets of bubbles, attached to either side of a rope hanging across two pulleys. The game contains a story mode for single player play. In total, the game features 640 levels. The console version features a level editor to either create and save a level, set a succession of levels, or to create an unlimited amount of extra levels and stages. It also has an alternative "story mode".
