The Can Opener is an abstract and experimental opener designed by player Claramay. The name comes from the way the first T-Spin Single is performed, needing to be rotated twice which emulates the "pop pop" sound that is created from opening a soft drink.

First Bag
- This guide will be following the original placements of the pieces. The mirrored version is also useful, for example, when S appears before Z.
This opener requires early O and Z, and possibly late L. Once the O and Z are placed, every other piece is free placement. It is useful to know how to place the J last, as follows:
An example of how the I can also be placed last is as follows:
Second Bag and Onwards
There are currently two continuations for the second bag.
Continuation 1
T-Spin Double
T-Spin Triple Route
From here, you can tuck an L and J under the overhangs to create a 5-4 stack, or tuck either the L or J then execute a T-Spin Mini Single then enter midgame.

Fractal Route
If you delay the first T-Spin Double, it is possible to create a fractal. This results in a very messy board however, which requires downstacking into midgame. Because of this, it is recommended to take the T-Spin Triple route instead.
Continuation 2
This is by far the cleaner and more versatile continuation.
It is possible to create more T-Spins from this board. Here is an example of a possible continuation (the stacking on the left is arbitrary):
This finally resolves into a 6-3 stack.
(Note from Claramay: I had a bit too much fun making this, oops!)
