Puyo Puyo Sun

The name of Puyo Puyo Sun comes from a Japanese pun on san, and also indicates a new Puyo brought into the game. Also released for the PC, which was also translated into Korean. A cut-down port of the game to the Sega Genesis featuring just the versus mode, titled VS Puyo Puyo Sun, was released as part of the Sega Genesis Mini 2 dedicated console in 2022.

Like the previous games, Puyo fall from the top of the screen in pairs, can be moved left and right, and can be rotated clockwise and counter-clockwise by 90°; if the third column from the left fills up to the top, the game is over. The offset (Sousai) and all clear (Zenkeshi) rules from the previous game remain, but every time the player counters, special garbage falls on the screen in a preset pattern (in the Game Boy version of this game, it falls randomly). Every time player clears the screen however, Sun Puyo fall on the screen since the All Clear bonus is removed in this game. Ports of this game have music slightly different than the arcade original. The Game Boy Color version allows players to unlock special artwork, which can be viewed in the Nintendo 64 version of Puyo Puyo~n using the Transfer Pak.

Satan (Dark Prince in the series' English localizations) has used special magic to make the Sun bigger on a remote island, hoping to create a paradise where he can relax surrounded by girls in bikinis. Draco Centauros, in the Easy difficulty, uses this as an opportunity to find a spot to get a tan, but gets a sunburn in the ending. Arle Nadja and Schezo, in the Normal and Hard difficulties respectively, find the weather too extreme. Both of them set out to find Satan and stop his plans, but are repeatedly interrupted by others such as Zoh Daimoh, Draco Centauros after her storyline, Suketoudara, Lagnus the Brave (Ragnus in later games), Rulue, and even each other. The ending depends on the playable character; Arle's ending involves Carbuncle firing a laser at the Moon and turning it into a second sun, and Schezo's ending involves him shattering the crystal Satan had used to enlarge the Sun and then being beaten up by Satan, with Schezo asking, "What's with this ending!?"
