|All clear bonus
|+2 chain in your current Fever chain amount
When the match starts, every player is either in a Fever state if playing Puyo Puyo or Lucky Attack if playing Tetris. Both Puyo Puyo and Tetris players are given preset boards and the objective is to clear as many boards as possible. Puyo Puyo gives preset boards that act like the ones from Fever, except they are organized in a way to make getting All Clear easier. Unlike in Fever and similarly to Party and Mission Puyo, topping out does not cause the player to lose the game; instead, the player is simply given a new preset chain. Tetris players are also given preset boards, however their boards involves using a specific type of Tetrimino in order to clear out the board ina specific way, with higher levels adding more Tetrimino types into the mix. Regardless, if the player completes the board correctly the next chain length will slightly increase, but if the player clears the board incorrectly the chain length decreases.
At the top center of the screen is a timer that counts down from 60 seconds (40-80 in custom rules), and during this time every player is tasked with creating as many chains as possible. When time runs out, both players stop playing Fever/Lucky Attack, but pausing until a player makes their last move. All the power from chains then gets absorbed in a black hole, and then explodes with the titular Big Bang. The game then calculates the power of every player, and whoever has the strongest power will inflict damage onto the other players. Damaged players will have their health bar depleted, and their board will have a broken glass effect that gets worse with more damage. Once the health of an opponent is completely drained, their board shatters and they are knocked out. The game repeats these rounds until the last player stands.
Cosmetically during the Big Bang, characters will attack using their final chain animation, for example Arle's Bayoen.
In Puyo Puyo Chronicle and Puyo Puyo Tetris 2, characters now use their 3rd in Fever, 5th in Tsu chain animation during Big Bang, for example Arle's Brain Dumbed/Mind Blast.

- Big Bang is the only mode introduced in Puyo Puyo Tetris to appear in a game other than Puyo Puyo Tetris 2.
- In Big Bang, Tetris uses a unique voice pattern from other rules (aside from Fusion), resembling that of Fever, in which the character's generic chain lines are used instead, and a spell plays at the end of a preset board, regardless of whether or not involving Tetrises/T-Spins.
- In Puyo Puyo Tetris 2, a voice clip does not play when performing Tetrises for unknown reasons. It may also not play if a board finishes with L/J tetriminos.
- In Puyo Puyo Tetris 2, a character's counterattack voice clip can sometimes play while playing as Puyo Puyo, even though the "standard" neutralizing does not exist gameplay-wise.
