Hmm... I see. Thanks for the report. There must be some kind of bug... 
  if(piece_buffer.length % 7 == 0)

  {

    // Make a new piece buffer.

    // Don't bother randomizing it; we will apply the bad-piece algorithm for it in any case!

    while(piece_buffer.length < expected_piece_buffer_length)

      piece_buffer.push( piece_buffer.length % 7 )

  }
Who can figure out why this code fails to produce an equal distribution of pieces (with expected_piece_buffer_length being 7 at levels 0-1 and 14 at levels 2-5)?
EDIT: Ohh, I think I know why. Removing the % 7 from the "if".
EDIT: Fixing that problem caused another: The game knows how useful the "I" pieces are in my playing style. Because it really does not want to give them, it delays them as long as possible. With the 14 piece buffer, that is for 12 turns, assuming the previous one was also given as late as possible. Then, because it really needs to catch up, it ends up giving two "I" pieces in a row in order to balance the odds. Hmm...

As for the feature selection buttons, I thought about that, but I think it confuses people to have too many control buttons. Most people just use the default settings. Even the "level up" button is stretching it... Hm.

It's called Futilitris because of the way it attempts to prevent you from getting useful pieces (futilely).

A note to the author: if you're going to go down the baloney "try to restrict useful pieces" route, reduce the number of T pieces. They're waaAAaAaAaAaAaaaAAaaAay more useful than the I blocks.

This is not the actual reason.

Uh, no it doesn't..? If it does that's only a tiny bit of it. Very tiny. The futile part is how it makes it harder and harder to actually see what is happening. The quote on the page pretty much explains it all..

In the game I linked to, you can actually get a T piece.
Dunno if it's an error that it fails to determine an useless piece, or that you can really make a situation any other piece would be more useful.

Ooooooh yes it does. I ran three trials in the field I posted a screenshot of. The most recent one is on the far right edge: see that orange L block down on the bottom? I specifically waited for 30 pieces to see if another one would show up, and it never did. The instant I drop a red I block on it, poof: orange L block in the Next window. Same deal for the other two trials. Oddly coincidental, don't you think?

I also noticed, just like Bisquit's little code snippet up there, that the I blocks almost always came in pairs, after a mild drought. It's far too consistent to be a coincidence; I'd put real money on this game trying to keep good pieces from you.

That code snippet is from Bisq's tetris, not the one I linked. There are several here. And futilitris is futile still for a completely different reason.

It definitely has a "don't give the piece that will clear the most lines" or "avoid clearing the bottom row" or something to it. Though I believe it takes a while to start doing that. Maybe after the eagle's cry?

Though the reason it is called futilitris is because it takes more and more troublesome to make lines (because of ALL the factors, including piece generation) to no foreseeable end or purpose: It DOES get pretty bad with it not giving pieces that clear the bottom row you later on because it means you have to prepare another layer, which after a while gets pretty large.
It really punishes you for leaving any hole anywhere.

Re: Futilitris, at no point did I notice any bias towards or against some piece when I played it.

Yeah I was just playing it for like half an hour and it definitely would not "refuse" to give me the pieces I wanted. If something doesn't come for awhile, it later comes quite frequently, and that could pose a problem depending on your style but I had no issue quickly building on the horizontal at any point.

As has been mentioned, it's named what it is for a reason:

fu·tile/ˈfyo͞otl/
Adjective:
Incapable of producing any useful result; pointless.


There's no point in trying to clear lines, because it accomplishes nothing. Any time you make a completed line, the game moves the goal posts further away.

Did you notice how the "rows" counter never increases?



The fact that you argue over the piece generation shows that you missed the point of this game pretty badly.

It's more that I wanted to make a self-deprecating joke about myself having the ability to do an utterly pointless activity for so ridiculously long that you actually accomplish what looks like a futile effort.

Probably driving the game's joke to the ground with that, though. Oh well.

The more I play it, the more I feel like it's perhaps even easier than normal tetris. Increasing the queue doesn't make it harder, it makes it easier; sure, you play with a bunch of bad pieces immediately in play, but then it levels out, and just before the queue is refreshed you get a glut of the most useful pieces. It's very manipulable.

I see. Thank you for the analysis.

If your playing style hinges on a particular piece occurring every so often, an algorithm that _must_ balance the odds once in a while will satisfy your playing style perfectly.
As long anyway as you aren't doing something stupid like making a wasteland of 1-wide wells to be clumsily blocked by a square piece that has no place to go.
Is there any possible other way to go about this? I.e. fair, but still screws you over...

How my program decides the next piece, barring the balance equation, is that it uses a state-of-art AI algorithm by Pierre Dellacherie to evaluate all possible placements for all pieces (only dropping though; no slides, wedges or t-spins), and chooses the piece for which the best possible placement had the worst score compared to the other pieces. The AI evaluates things such as two-dimensional Fourier transform of the board, choosing an option that has least high frequencies*, the cumulative depth of 1-wide pits, number of piece cells eroded by a possible line clearing, the height of placement for the center of the piece on the playfield, and number of empty cells hiding beneath filled cells.


*) Not really, but for a mathematically inclined person what the algorithm really does in that step, this is the easiest explanation. It really just sums for each column and each row how many times the field transitions from "vacant" to "occupied" or the other way around.

To help make the player squirm a bit more,
I upgraded the Pierre algorithm into El-Ashi alorithm. Let me know if you see any difference! http://bisqwit.iki.fi/jsgames/worstpiecegame/

Does this take slides into account? If not, you can abuse these sorts of generators by spending the first few pieces creating a large overhang with enough space at the side to slip pieces through.

It doesn't. It only considers straight drops. I doubt your suggestion is worth the effort though...

It probably isn't, because as time goes on you need increasingly specific pieces to fit in the overhang (as you do not have much room). No gravity makes it easier, though.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
