Virages

The most efficient way to chain is to build across the board instead of vertically. However, this presents a problem once you reach the wall. To continue chaining, you'll have to start stacking vertically. This act of stacking vertically is called Transitioning. After you construct a Transition, you can start chaining back in the other direction. Many players have trouble constructing Transitions due to the attention to color that it requires.

Vertical Transition

This is the most straightforward way to build a transition. You simply build straight up and then put the necessary colors on top (green/blues).

Stairs-Base Chain-Cut

If you are using Stairs as a base, you should notice that it's troublesome to make a chain in which Columns 1 and 3 are the same color (Columns 4 and 6 if you're transitioning on the right).

GTR

GTR (Great Tanaka Rensa) is the most famous way to construct a transition. It's incredibly flat, quick and easy to make with most combinations of colors, and is used by both beginners and experts. There are also several variations of it.

Normal Form

Basic Form	2-2 Stairs	Sandwich	L-Shape	Flat Stacking 1	Flat Stacking 2

New GTR

New GTR is similar to GTR, except with a larger trigger point. One weakness of normal GTR is that using it as opening may cause you to miss out on All Clear starts. By using this extra bulky version, you reduce the probability of that happening. It all depends on what colors you're getting though.

Basic Form	Variation	L-Shape	Flat Stacking	Reversible

Raised GTR

GTR, except with stuff below it. Useful for putting pressure on your opponent because it can easily be reversed into a Hellfire.

Basic Form 1	Basic Form 2	Hellfire 1	Hellfire 2

Misuken GTR

Misuken GTR is simply GTR except bulky, allowing for two different trigger points.

Basic Form	1-2-1 Sandwich	3-1 Stairs

Kanto Stacking

Kanto Stacking (関東積み) Can function as both a transition, a reversible Hellfire, and a Tail end.

Sullen GTR

Sullen GTR (フキゲンGTR, fukigen GTR) is commonly used with Flat Stacking. Don't confuse this with New GTR.

Basic Form	Flat Stacking	Sandwich	L-Shape	Tanaka Special

GTGTR

Something Kuroro made up. GTR except complicated.

ETR

Also another thing Kuroro made up. Basically, it's when you royally screw up your GTR from harassing a lot on top of it. Don't do this form ever.

LLR

LLR is named after the Puyo shapes within the base. Referencing the Basic Form example below, it goes: L (red), L (blue), R (for reversible, the green). You'll need to know how to tail to make this form useful.

Basic Form	Variation 1	Variation 2	Hellfire	Reversible

Pechura

Pechura (ペルシャ式) is similar in concept to LLR.

Basic Form	Variants

Raised L-Shaped Base

Preemptively adding in a Puyo at the bottom makes it easier to chain on top later on.

L-Shaped Zabuton

Gets its name (座布団L字) because it looks like a Japanese sitting-cushion.

Basic Form	Diving Tail	L-Shape	GTR Instead	Same-Color Trans.	Reversible

Slug Folding

Slug Folding (なめくじ折り返し) contains elements of L-Shape. By constructing it as shown below, you'll have two trigger points. If you're rushing to complete your chain, there'll be less pressure and need for you to get a specific color since you have two options.

Sodomy Stacking

Sodomy Stacking (男色積み) gets its name from... use your imagination! This, and its Raised form, are popular ways to do a transition.

Sanagawa Transition

Using elements of Dam Stacking, the Sanagawa Transition (真川折り返し) can double as both a Power Chain (blues) or a normal chain.

Beetle

Not exactly a transition, but Beetle (甲虫連鎖) refers to making a huge Tail on top of the transition to pad it. This is typically done using Saitou Special. See also: Multiple Stacking.

Alpine Flower

Alpine Flower (お花畑連鎖) can double as both a mega Hellfire and a Transition.

Basic Form	Hellfire	Transition

Multiple Stacking

Not exactly a transition, but Multiple Stacking (多重折り) refers to padding your transition to use up more wall space and make your chain a little longer. Useful if your opponent is rushing you and you need to construct a Counter. Also useful if you want to counter a harassment; all you have to do is leave out a few Puyo from the stack so the rest of your chain doesn't pop.
