first, in order to do t-spin, you need to buy a computer, right? so here we have two options:
1) ask mom for money
2) go, get a job at a factory and get your hard-earned money
okay. now we have money. what should we do next? of course, they can easily be spent, for example, on steam or on some trinkets, but let's imagine that we are so goal-oriented with tetris that we have saved a lot of money. then we will have to go to the store in any case, talk to people, and this is always difficult, because people can sometimes misunderstand each other. so in order to go to the store, you need to work this point out with a friend so that there are no awkward situations. wait, you don't have friends? then you had to find them at work, or go to work anyway (even if you asked mom for money). Let's say you've achieved an unattainable achievement in our time: you've got yourself a real friend. Now you need to ask him to practice with you to buy a new computer. Well done, you've acquired vital skills, please don't forget them, you might need them again. Well, then we need to figure out what kind of computer is suitable for Tetris. There are three different groups:
1) Pro players. They mostly turn off all the effects, they're cool, they eat pizza and they don't need a very powerful PC, because they already know Tetris inside and out, that they can even run it in their heads.
2) Middle players. So to speak, those who like to play after a hard day at work. They usually don't bother with any tricks, don't play Tetris League. They don't know what settings are. usually since they are not hardcore cyber athletes they constantly complain that the computer can't even handle Tetris that's what I've lived to see
3) people who just found out what Tetris is, tried and quit

after we found out who we are in this universe we go buy a computer with RTX ULTRA 8090 TI SUPER MAX so that Tetris certainly doesn't crash and that's the most important thing. after buying a computer you in most cases need to set up and install the Internet in your home. we call the provider to get you the Internet (skills will always come in handy in life). you give a little money and then go install Tetris, Discord, Steam... all the classics.

omagad we finally got into Tetris and a lot of time and effort was spent on it. next we need to learn how to do a t-spin. for this you can go to very cool site about t-spin [four.lol] and see how they are actually done. after a few weeks you will learn not only to do them, but simply to notice that they are just everywhere.
congrats, you have learned to do a t-spin!!
