Can Opener

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. The main route for the opener involves a T-Spin Single, T-Spin Double, and T-Spin Triple.

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 it can be converted into a Fin T-Spin Double.

Can be followed up with another T-Spin Double, however it breaks Back-to-Back.

Continuation 2

This is by far the cleaner and more versatile continuation.

T-Spin Double

T-Spin Triple

The I can be placed last as follows:

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!)

Continuation 3

T-Spin Double

T-Spin Double

Trinity

More stacking may be required between T-Spins. This only shows an example of a stack.

Alternate First Bag

Below is a different way of placing the L. The continuations for this placement has a more freestyle approach.

T-Spin Double into T-Spin Triple

Trinity

The stack on the left is freestyled.
