Puyo Puyo!! 20th Anniversary

'Puyo Puyo!! 20th Anniversary' is a developed by Sonic Team and published by Sega. The game honored the twentieth year of the Puyo Puyo series, and was first released for the Nintendo DS in July 2011, and later for PlayStation 2, PlayStation 3, PlayStation Portable Wii, Nintendo 3DS, Xbox 360 and Microsoft Windows in November 2011.

Gameplay
In total, the game has 20 modes of gameplay, including 8 new modes, and 5 hidden modes from Puyo Puyo! 15th Anniversary. Except in Mission and Pair Puyo modes, a player is eliminated when he/she tops out, and the last player (or side) standing wins the round.

When playing through story mode, you can select which gameplay mode you like. The original Puyo Puyo rule and Tsu rule are always available, along with three others which vary depending on the opponent character.

Standard Modes

 * Puyo Puyo (ぷよぷよ, Puyopuyo)
 * This mode plays like the original Puyo Puyo, using the original Puyo Puyo rule.


 * Puyo Puyo Tsu (ぷよぷよ通, ''Puyopuyo tsū)
 * This mode plays like Puyo Puyo Tsu, using the Tsu rule.


 * Puyo Puyo Fever (ぷよぷよフィーバー, Puyopuyo fībā)
 * This mode is played using the fever rule (that is, Puyo Puyo Fever and Puyo Puyo Fever 2's version), in that you gain fever time when someone counters nuisance Puyo that you sent them. The "squishy" field effect after every step of the chain in fever mode from Puyo Puyo! 15th Anniversary and Puyo Puyo 7 is not present. It also uses the fever chains from Puyo Puyo Fever and Puyo Puyo Fever 2, ditching the ones used in Puyo Puyo! 15th Anniversary and Puyo Puyo 7. Any chains that used to all clear themselves have been slightly modified (usually by adding a Puyo or changing the color of a Puyo) to no longer all clear themselves. For some reason, the picture for this mode in the rule select depicts a Puyo Puyo! 15th Anniversary/Puyo Puyo 7 fever chain.


 * Mission Puyo (なぞぷよ, Nazo puyo)
 * This mode plays like Mission mode from Puyo Puyo! 15th Anniversary and Puyo Puyo 7. In this mode you have to solve different tasks in order to win. Nuisance Puyo aren't present in this mode. Reaching the X's at the top of the screen only clears your field; it does not make you lose.

Returning Modes

 * Puyo Puyo Sun as a standard mode (ぷよぷよSUN, Puyopuyo SUN)
 * This mode plays like Puyo Puyo Sun, using the Sun rule.


 * Mega Puyo Rush (でかぷよラッシュ, Deka puyo rasshu)
 * This mode is a non-stop fever-like version of Puyo Puyo 7's Mega Puyo Rush Transformation mode.


 * Mini Puyo Fever (ちびぷよフィーバー, ''Chibi puyo fībā)
 * This mode is a non-stop fever-like version of Puyo Puyo 7's Mini Puyo Fever Transformation mode.

New "Gimmick" Modes

 * Mini Puyo Excavation (ちびぷよはっくつ, Chibi puyo hakkutsu)
 * This plays like Excavation from Puyo Puyo!! 15th Anniversary, except mini Puyo are used instead. Uses quick drop.


 * Gust (とっぷう, Toppū)
 * Wind shifts your Puyo over to the left/right, depending on which direction the wind is blowing. Uses classic rules and quick drop.


 * Slot (スロット, Surotto)
 * A roulette takes place after every less, 30, 40, or more Puyo cleared (both players combined) and the effect of the roulette is placed either on the player who cleared the last of the Puyo (if it is a good effect), on the other player (if it is not a good effect), or both players. The effects are:

Field Spinner (フィールド回転, Fīrudo kaiten)
 * Rotate the fields 180° (180 dergees).

Chain Preset Get (連鎖のタネゲット, Rensa no tanegetto)
 * Replace a field with a preseted 4 chain.

Field Swap (フィールド交換, Fīrudo kōkan)
 * Swap your field with other player's field.

Freeze (こおりづけ, Kōri dzuke)
 * Cover all Puyo in ice blocks on opponent's field.

Nuisance Present (おじゃまプレセント, Ojama puresento)
 * Drop 12 hard Puyos (2 Hard Puyo Rows) on opponent's field.

Nuisance Clear (おじゃまクリア, Ojama kuria)
 * Erase all nuisance Puyo on the player's field.

Speed Up (スピードアップ, Supīdoappu)
 * Cause opponent's Puyo to immediately drop and speed up their chains. It's called an instant drop.


 * Foursight (よんてさき, Yontesaki)
 * Your 4 next 2 Puyos are shown instead of 2 next 2 Puyos. Uses the Tsu rule and quick drop.


 * Blocks (ブロック, Burokku)
 * Unclear-able blocks (Block Puyo) are placed in a preset pattern, randomly chosen from several such patterns, one of which has only a two-column wide gap half way up the board. Uses the Tsu rule and quick drop.


 * Active (アクティブ, Akutibu)
 * You can still place Puyo during a chain. Uses classic rules and quick drop.


 * Cross Spinner (クロスかいてん, Kurosu kaiten)
 * Your field splits into 2 (the first 3 columns and the last 3 columns), and then each field rotates 180 degrees every 10 seconds. Based off of Spinner mode from Puyo Puyo! 15th Anniversary. Uses quick drop.


 * Quartet (カルテット, Karutetto)
 * Your drop set consists of 4-piece Puyo. Uses quick drop.

Hidden Modes
To unlock the hidden modes, keep buying advice from Popoi in the shop. Occasionally, instead of receiving advice, you will unlock one of these modes. These modes include:
 * Non-Stop Fever (ずっとフィーバー, Zutto fība)
 * Plays like Non-Stop Fever from Puyo Puyo! 15th Anniversary, but includes quick drop. For some reason, the picture for this mode in the rule select depicts a Puyo Puyo! 15th Anniversary/Puyo Puyo 7 fever chain.


 * Excavation (はっくつ, Hakkutsu)
 * Filling up the fourth column will no longer cause the player to lose and uses quick drop.


 * Mega Puyo (でかぷよ, Deka puyo)
 * Plays like Giant Puyo mode from Puyo Puyo! 15th Anniversary, but includes quick drop.


 * Ice Blocks (こおりづけ, Koorizuke)
 * Filling up the fourth column will no longer cause the player to lose and uses quick drop.


 * Spinner (だいかいてん, Daikaiten)
 * Plays like Spinner mode from Puyo Puyo! 15th Anniversary, but includes quick drop.

Pair Puyo
Pair Puyo (also known in Japan as ペアでぷよぷよ, Pea de Puyopuyo) is a special mode with its own rules in which four players can play in two teams of two. Within each team, players share Nuisance Puyo, and also share "lives": if a player's field fills up, instead of having to wait for the match to be decided their field is simply replaced with a preset 4 chain at the cost of one life. The game can be played with one, three or five lives per team, and is decided once all lives of one team are lost.

Gameplay is based somewhat on Transformation mechanics (quick drop, continuous offsetting, and dropsets) except without the transforming. Instead it uses 2 new features:
 * Extra Chains: If you start a chain (even a 1-chain) during your teammate's chain (or at least, before they place their next Puyo pair), it increments a counter which will eventually be used to send a large amount of nuisance to the opposing team, similar to how the counter in Mega Puyo Rush mode works. This feature allows both players to indefinitely delay nuisance falling on them by alternately building and firing short chains.
 * Synchro Chains: Firing chains of the same length (3 or more) at the same time adds bonus points and sends additional nuisance to the opposing team.

Shop
Similar to the way Puyo Puyo Fever 2 worked, you can spend the points you earn in story mode at a shop. However, instead of gameplay items that affect the outcome of the match, the shop sells various unlockables such as Puyo skins and alternate character costumes, and alternate character voices. Popoi is the vendor, and the music is a softer remix of his theme.

Trivia

 * The music used in the opening is the same as the Game Gear version of Puyo Puyo's title screen.
 * The characters from Puyo Puyo 7 all have different dropsets. Interestingly, the characters they replaced are all present in this game.
 * Clearing Nuisance Puyo is now factored into the player's score (it is unknown if this is intentional or a bug).
 * This is the first game since [[Puyo Pop (video game)|Puyo Pop] that neither introduces new characters nor re-introduces Madou-era characters. All characters in this game have been present in Puyo Puyo! 15th Anniversary and/or Puyo Puyo 7 as either a playable character or non-playable/cameo appearance.
 * This the second game introduced the alternate voices after Puyo Puyo! 15th Anniversary. This does only apply to the main protagonists, Satan and Ecolo in this game, but in the subsequent games, it does apply to all of the characters.
 * This game includes the return of the 7 cast from Puyo Puyo 7 (except for Dark Arle).
 * Skeleton T is the only playable individual (not counting the other two skeletons) from Puyo Puyo 7 to not be present in this game. He shares this position with Harpy overall.
 * The music used in the epilogue is a remix of an unused piece of music in the DS version of Puyo Puyo Fever 2.
 * Which in turn, was also an unused piece in the GBA version of Puyo Puyo Fever.
 * In this game, along with Puyo Puyo Tetris and Puyo Puyo Chronicle, all characters have their voice clips saying Sega before the title screen. The international version just has the logo left silent.

 * ”Yamete~!”, one of Arle’s unused dialogues from Puyo Puyo Tsu, is finally used as a heavy damage quote for her in this game.
