User:Poochy/Konoha Mode Analysis

The randomizer appears to be history of length 3. Until some hidden condition is met (5 Bravos?), it will only pick from pieces not in history, so any 4 consecutive pieces dealt are all different until that point.

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. Use held I first, then hold L if necessary.

→

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 JTL: Hold the first piece, reduces to above cases.

LJT:

→

→

JLT: Symmetrical to 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.

→

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

→

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.

Case 9: +O-T

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

→

Hold L.

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
