Please help improve this list! If you know of a completed game (or one that has at least 7 gyms) that isn't listed or if there is a hack that doesn't belong here, please let me know in the comments.
There are a few hacks that aren't complete but have significant progress, so I've added them as well.
Improvement type hacks (that don't change the story) are on this list.

An iconic entry of the beloved Puyo Puyo series has been fully translated into English!
Puyo Puyo!! 20th Anniversary takes place after Puyo Puyo 7. This time, our Puyo 7 protagonist Ringo Ando suddenly finds herself teleported to another dimension! Luckily, it’s the dimension of her world-crossing friends who can help her find her way back home. Featuring 24 individual routes, Puyo Puyo!! 20th Anniversary celebrates the shenanigans of its diverse cast as they Puyo pop their way through each and every challenge!
Puyo Puyo originated as a spinoff of the classic and dramatic dungeon crawler Madou Monogatari, its unique action-puzzle gameplay has both attracted a committed fanbase in Japan and vaulted it into the world of esports. With its recent resurgence in English-speaking territories, now’s the perfect time to pick up Puyo Puyo!! 20th Anniversary and meet its cast!
This patch is for the Nintendo DS version, made possible by the team at Precise Museum along with some additional help from Puyo Nexus.
