Those looping patterns should work in every Tetris game with hold feature and bag randomizer (almost every official Tetris game since 2002), as long as gravity doesn't become too high. Here are 2 fumens showing how I want to stack each bag.

Note that you cannot stack infinitely in both cases because T-Spin Double-only makes your stack grow by 8 filled cells per bag. However, there's a high chance that you can stack for a long time with the first technique, if you burn lines from time to time properly.

Also note that both techniques aren't really meant to be used seriously. All that softdropping makes the execution rather slow - especially in official games. And techniques like Infinite TST or ZT Stacking have a higher efficiency.
