Future testing

CT suggested a couple more scenarios:

Does gold dominate over top?

More difficult: Does top dominate over left?

CT said this one was deemed impossible to test (and thus immaterial to a description of the algorithm), as the other O piece can't fit through. However, it certainly is possible (though difficult) to test this by making a hurdle:

The O pairs at top and bottom can be replaced with I pairs, J pairs, or L pairs, but the Os in the center must remain O.

Actually, the "O pairs" at the top and bottom can't possibly be Os or else the Gold square priority will ruin the test. --Colour Thief 21:25, 1 December 2006 (EST)

Ok, I've tested these in Tetris Worlds on GC. It is left biased and down biased, which is different than TNT. When I tested the relative priorities (note this took the mirror image of the general hurdle test above) I found that Gold > Down > Left. I'm not sure how you'd like to fit this information into the articles, but go about it as you see fit. And be sure to test TNT as well; I'm curious to see the results. --Colour Thief 21:58, 1 December 2006 (EST)

I created a new rule in nullpomino and tested:

Drop O

I tried the hurdle method in the real New Tetris, The after many attempts and found out that top right dominates here too.
