#2Has anyone implemented a version of tetris where the player can toggle the randomiser mid-game?

#3Is the Tetris Grandmaster 3 system basically the same as having five bags? So, instead of a bag with 7 pieces, one of each type, you have a bag of 35 pieces, 5 of each type. I'm having trouble picturing the difference.

> When a piece is dealt, instead of removing it from the pool, it is replaced with the most droughted piece
So as I understand, the contents of the bag remain in flux, and pieces that don't occur in the history as much start to appear in the bag more.
It's interesting to think about how much tuning this required for them to get it right, my immediate worry is that this would create an oscillating system.

In the bag system, eventually your bag runs out of pieces and you move to a new bag. That's not the case for the TGM3 system. You always have 35 pieces, when you "take one out" of the bag it's immediately replaced before any other pieces are drawn. So there's always a pool of 35 pieces to choose from, and the contents of the pool will change to include more and more of the pieces you haven't drawn until you inevitably draw one, then it will change to whatever the new least drawn piece is. It's constantly self-correcting in that way, but I suppose with a really unlucky sequence you could end up with a lot of one piece in the pool and then get that piece repeatedly.

#6NES Tetris didn’t have a uniform randomizer? How did I not know this!?

From a purely pedant point of view, the star item in 4 player versus in Tetris DS switch the standard 7-bag randomizer into one that only deals the I piece.

And this article describes a simplified version of the NES Tetris randomiser. The actual one is barely distinguishable from the described one, but is technically a bit biased[0]. I made a small script to compare randomiser probabilities a couple of months ago[1], in which I wrote a vaguely readable version of the NES randomiser.

#9I grind on NES Tetris nearly every day at speed 9, game-B. My personal goal is playing "perfect" games where only lines are used to complete rows. These games are by definition finite and sometimes end rather quickly given the nature of tetromino selection. When that gets boring I switch to speed 9, game-B at level 5 which is simply a battle for survival for 25 lines. This is a bit easier.
I will need to see how I fare against a newer version of the randomizer one of these days.

#10In the "1 Piece history with 1 roll" code, a global variable `piece` is introduced. There should be a `let piece;` at the top of the function body to scope it locally.
