> TLDR, most modern tetris games, including tetris 99 select a permutation of the 7 unique pieces every 7 pieces; this means even though Tetris 99 shows you the next 6 pieces, you may know more about the next pieces.
Wait, is this true?
I always assumed each piece was selected perfectly randomly, making it possible (though rare) to get the same piece 3 times in a row.
If what you're saying is true, then that mean there should never be more than 12 pieces between I pieces, and if you get two in a row, then it'll be a minimum of 6 before you see another.
Which...all seems within the realm of possibility. Tetris always seemed really good at having a very even spread of pieces without "streaks".
- trothamel 2y agoYes, it's part of the (leaked) Tetris Guideline. https://tetris.wiki/Tetris_Guideline https://tetris.wiki/Tetris_Guideline
- toast0 2y agoYeah, it's true. Old games like gameboy and NES tetris (either flavor), and the Atari arcaee machine were one piece at a time random, and not particularly evenly distributed either.
- vikingerik 2y agoThe Gameboy one attempts to compensate for clumpiness by reducing the chance of repeating a piece, but it turns out that that's even bugged so that the overall randomization is unbalanced. https://harddrop.com/wiki/Tetris_(Game_Boy)#Randomizer https://harddrop.com/wiki/Tetris_(Game_Boy)#Randomizer L: 10.7 % J, I, Z: 13.7 % O, S, T: 16.1 %
