User:Poochy/Konoha Mode Analysis

Randomizer ensures any 4 consecutive pieces dealt are all different.

Case notation: +X-Y means X held, Y missing from next piece preview.

Case #		Missing
		I	L	O	T	J
Held	I	1	2	3	4	2
	L	5	1	6	7	8
	O	3	6	1	9	6
	T	10	11	12	1	11
	Z	5	8	6	7	1

Case 1: One of each piece

Can be mirrored.

//TODO: Permutations that don't work with this build or its mirror image.

Case 2: +I-L, +I-J

Diagram for +I-L, mirror for +I-J.

//TODO: Permutations

Case 3: +I-O, +O-I

Use held I or O first. Make a 4x2 with I's or O's. (Note: For +O-I in 20G, build the 4x2 on the right to ensure the second O can reach its destination.) With remaining L, J, T, clear depending on their relative order:

TLJ: (hold J until after second O/I if necessary)

→

TJL: Symmetrical to TLJ.

LTJ or JLT: Hold T, reduces to above cases.

LJT:

→

→

Case 4: +I-T

Use held I first, then hold the second I if necessary. Build depending on relative order of L, O, and J, then finish with I for a Tetris Bravo:

OLJ, OJL	LOJ, JOL	JLO, LJO

Case 5: +L-I, +J-I

Strategy for +L-I, mirror for +J-I.

Build depending on relative order of L, O, and J:

OJL, OLJ, LOJ: Use held L first, then hold the second L if necessary.

→

JOL: Same as above. Hold J and use the held L, then hold the second L and use the held J. Alternate no-hold strategy:

→

LJO, JLO: Hold J

→

Case 6: +L-O, +J-O, +O-L, +O-J

(Note: For +O-* in 20G, build the 4x2 on the right to ensure the second O can reach its destination.)

Diagram for +L-O, mirror for +J-O. Hold J if necessary.

→

Diagram for +O-L, mirror for +O-J. Hold L if necessary.

→

Case 7: +L-T, +J-T

Diagram for +L-T, mirror for +J-T.

//TODO

Case 8: +L-J, +J-L

Diagram for +L-J, mirror for +J-L.

→

→

//TODO: Permutations

Case 9: +O-T

(Note: In 20G, build the 4x2 on the right to ensure the second O can reach its destination.)

→

Mirror only the left two columns if J comes before L, since O's spawn in columns 3 and 4. Hold L or J (whichever comes second) if necessary.

Case 10: +T-I

//TODO

Case 11: +T-L, +T-J

Diagram for +T-L, mirror for +T-J.

If I comes first, hold J for Triple Bravo:

Otherwise, use held T first, hold I:

J before O	O before J

The above will not work in 20G for TIOJ or TIJO, in which case save the held T for last and use the following alternate builds:

	TIOJ →		→
	→ TIJO		→

Case 12: +T-O

//TODO
