The situation is actually rather ambiguous as, while iPod/Splash/TNC/Evo were all consistent in removing such T-spins, Zone and TOJ - two games which in particular must have been under heavier influence by the original guideline setters than other games - have slightly different behavior regarding those spins.
I think you guys are missing Caithness's point here. One of the guideline requirements for a T-Spin is that the last operation before a piece locks must be a rotation. 3-corner T doesn't mean anything if the last move was a shift or drop. Deep Drop doesn't really change anything.
tetris zone ended up removing t-spin triples. toj is the exception to the rule, and i personally believe they kept it simply cause they based most of their game on tetris ds gameplay.
I know it shouldn't in standard Tetris. But the context was a suggestion that puzzle games be based on more realistic physics. How quickly we forget... Deep drop would let you do this even in Arika rotation.
EZ T-Spins. T-Spin minis. Well, perhaps Tetris Online US doesn't have TSTs/EZ T-spins, and you're basing the "exception" assumption on knowledge of that further example... As you're obliged to keep mum, I wouldn't know.
