Volcano DT is a long Double Triple Cannon opening setup, with the attack sequence of TSD→TST→TSS→TSD→TSD+Tetris→TSD→Perfect Clear. It is always possible to do a 22-line Perfect Clear. The setup is discovered and named by a Taiwanese player, Octupus Tea.

Seventh bag and 22-line Perfect Clear
There are several possible routes for the 7th bag and 22-line PC at the 8th bag.
Fallback A: always skim TSD
This pattern uses the 6th bag A and breaks Back-to-Back in the 7th bag. It is easier to build this setup than to build Fallback B.
Fallback B: always TSD
This pattern uses the 6th bag B and does not break Back-to-Back in the 7th bag. One may need to wait for gravity and/or perform tricky rotations and movements if Z or J comes after L.
Pattern A1: skim TSD
This pattern uses the 6th bag A and requires I before J in the 7th bag. It yields more Tetris PC.
- Solutions with Tetris: Only solutions with over 10% Tetris PC chance are listed. This is not the full list.
Additional setups and continuations
Second bag C-Spin
It requires O before Z and L before J.
Fourth bag Fractal
This alternative setup is always stackable.
