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

Can be mirrored if J comes before L.

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)

Case 4: +I-T

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.
