Or ask jujube to create a TST setup with just T pieces... And I don't know about stimpy, but the randomizer feels a bit skimpy...
And if you don't buy rows 11-20 of the playfield: "All ... my ... friends... know the low rider." It appears the Tetris keiretsu has developed an effective weapon against cloners that does not involve the legal system. I'm not sure how a free software developer can simulate Korean style paid unlocks without implementing the tetromino game as a minigame within a larger game that has its own economy. It appears that a cloner would have to develop a social sim where the player has to earn a living by performing unrelated minigames before he can buy tetrion upgrades. (Shades of Shenmue?)
