Someone good at tetris would never take such a challenge because they know how much that is. While a mathematician who just want to make a catchy post seemingly would.
I believe that even if you sent the "worst" configuration of blocks, a really good player would be able to stick around for 500-1000 blocks every time (unless glaring mistakes), especially if they expect an attacker choosing the blocks. If the attacker chooses random, that would actually be an advantage since the real game chooses pieces almost at random (AFAIK it's not pure random).
So, this post is like challenging someone who's good at tennis at making 100,000 of shots every single time: it's just orders of magnitude so off, that the player would know you're a total noob simply for asking.
> In regular Tetris games, the speed at which the blocks fall steadily increases. This causes players to make more and more mistakes and, just like the holes in the S and Z columns, these mistakes will stack up until game over is inevitable. Ultimately, small mistakes due to the time constraints will likely be what causes your friend to lose the challenge, so you probably won’t have to wait 69,600 blocks to beat your friend.
Playing at such a speed for 10 hours is kind of insane. Playing it without error is not human.
