Puyo Puyo Tetris

Puyo Puyo Tetris is a crossover of Tetris and Puyo Puyo, a mainstream Japanese puzzle game which provided the engine for Dr. Robotnik's Mean Bean Machine and Kirby's Avalanche, published by Sega. It has been released for the 3DS, Wii U, Playstation 3, and Playstation Vita. It is the first game in the Puyo Puyo series to ever have DLC.

Differences from Other Games
The side bars are not an indicator of incoming attacks; incoming lines are shown on the top in Puyo form, while the side bars are reserved for visualizing how much attack power you store. This game has a Puyo-style story mode, a feature absent in many other Tetris games.

Modes
Puyo Puyo Tetris features a story mode and five main game modes.

VS
In VS mode, it is possible to make a match between Puyo Puyo VS Tetris (as in the Title of the game itself) not to mention Puyo VS Puyo, and Tetris VS Tetris. The Tetris side does not work differently from modern multiplayer Tetris games.

Swap
In Swap mode, you have two play fields: one W6H12 field where Puyo fall, and one W10H20 field where Minos fall. Every 45 seconds (as shown on the timer) you must toggle between Puyo Puyo and Tetris. Employing the swapping mechanism, one can, for example, clear a long chain while in wait for an I to fall and score a tetris and land a devastating attack.

Big Bang
You can play as Puyo or Tetris in this mode. If you play as Puyo, the rules are according to Endless Fever mode; premade chains fall from the top of the field, and you must either set it off, or extend it slightly for a better score. However, when playing as Tetris, you enter Lucky Attack mode, where you must clear pre-made patterns often by employing SRS Triples. After a set period of time, the timer stops, and compares the points the player has made. The one who made fewer points receives damage from the other, shrinking the health bar. The last one standing wins.

Party
Items like the Slot Mode in 20th Anniversary and Tetris Party fall from the top of the field, and you can gain those by clearing lines through them or popping Puyo next to it like getting rid of Nuisance/Garbage Puyo. This is the only game mode where a top-out does not result in a loss (cf. Tetris Friends). The winner is the One who Scores the Most Points. This is the most harshly criticized mode by far in the game.

Puyo-Tet-Mix
Definitely the most chaotic and hardest-to-learn game mode of the whole game, Puyo-Tet-Mix mode takes place in a playfield of W8H16, an average of the W6H12 Puyo field and the W10H20 Tetris field. Both Puyo and Minos fall in the field. Minos sink to the bottom while Puyo loop through and fall from the top after they are squashed. To send more damage to the opponent, the player must combine a Puyo chain with Tetris line clears.

Controversy
Most Japanese fans were excited by the announcement of the crossover, while some cautious ones thought that it would break no new ground, and instead even harm the series by butchering out older characters to make room for new "Tetris characters". This game is the first ever Puyo game to have DLC, while many fans loved the Puyo series for being a DLC-free haven.

Some overseas fans have wished this game to be ported worldwide, but others disagree that the Puyo series is not known enough abroad to make the crossover work without any misconceptions (e.g. Puyo is a Tetris spinoff).
