Stairball.org is up!

Nelson and I have decided to snatch www.stairball.org while it is still available, and I’ve been working on getting content up today.  I’m also updating links around the web that pointed to the old site at ajlvi.net.

Also related, Sunday afternoon at 1.30p during the Activites Fair on the main staircases of Parrish Hall we’re going to be holding a Stairball demonstration.  I’ll be teaching the game to new players and explaining some of the techniques for improved play.  Mike Rosenberg ’08, the best Stairballer I know (he certainly leads in our lifetime series) will be playing a game against me, and new players will be encouraged to try out the game.  Also, I’ll be taking names for the ALASSCA mailing list and will be trying to set up the league for later this year and a weekly Stairball night.  Anyone interested, whether you know how to play or not, is certainly encouraged to attend.

Sometime soon I’ll recount the story of the creation of Stairball, but first I have a couple of other word games to go through, including some patternfilling variants.

Patternfilling

I think that, since the semester is starting and there were some interesting developments this season, I should first endeavor to chronicle the games that came to fruition over the summer.

Patternfilling one of a few word disciplines that have resulted from me messing around with Lexpert, which could quite possibly be my favorite program in the world.  I believe that the Lexpert project started as a Scrabble player’s tool, but it also contains tools that can assist the crossword player, cryptogram cracker, and general wordplay enthusiast.  (It was a real boon in solving the Confounded Compounds!)

The inspiration for the concept of patternfilling actually came from a game of Literati that Ron and I played a few months back. Across the second row from the top were two copies of the letter I, placed one space apart, through which he created the word RICIN.  It got me wondering — how many similar words could have filled that slot?  In particular I was looking for five-letter words because of the restrictions on the board.  Thom and I searched for a little bit at his apartment the next day, lounging about, listening to Regina Spektor, and trying to fill the pattern ?I?I?.  Ricin, limit, timid, vivid, civic, … I think we wound up with sixteen or seventeen.  When I got home I finally had the genius idea to put it through Lexpert, which claims fifty-five matches for the pattern.

Then I started playing around.  ?O?O? gave sixty-six returns.  S???K — fifty-six.  Interesting words, too, like BORON and SMOCK.  I had an idea for how to make it a real exercise.  I wanted to keep the atmosphere of people lounging around and thinking up the words, but a strict back-and-forth isn’t feasible because one person will inevitably run out before the other one does.  Yet a free-for-all like Thom and I had isn’t really good either because whoever has more words off the top of their head will be favored in that case

The middle ground I hit upon was first played with Nelson, Karen, and I.  Players give words in turn, but only have 40 seconds (45? 60? We usually play 45 or 50 seconds when playing by IM, because timekeeping and typing is time-consuming) to come up with their word.  Once a player gives a word that fits the pattern, the next person’s time begins.  Once every player fails to come up with a word in succession, the group has one turn left to come up with a word to kick-start the rotation again.  If the group time expires without a word, the round is over.  (As I type this, I wonder if it would be better that, once everyone fails, it becomes a total free-for-all.  That is, once the final player’s turn has ended without a word, there’s a 40 second clock that ticks down to the end of the round, and once anyone says a word that clock resets, but there’s no more turn structure.  I bet we’ll play this way from now on.)

The first time we played we discovered an issue — if the final letter is a wildcard, invariably thousands of plurals are admitted.  But the point wasn’t to find cheap words that end in S. We’re supposed to be looking for cool words like RICIN and SWANK!  So more complicated syntax has since arisen, to help avoid the problem of cheap words and to promote more exotic patterns.  Here’s the syntax I’ve used for explaining patterns:

  • ? : Single wildcard.  So ????K would denote all five-letter words ending in K.
  • * : Variable-length wildcard.  *K denotes every word that ends in K (of any length).
  • V : Vowel wildcard.  When handwritten, this should be the capital letter V in a circle.  V cannot stand for Y.  ???VK is words that end in vowel-K, like CHEEK and BREAK.
  • X () : User-defined wildcard.  When handwritten, this should be the capital letter X in a circle.  X can stand for whatever is specified within the parenthesis.  To create the pattern for words that end in vowel-K or -yk, write ???XK (aeiouy).
  • +[?] : Must contain [?].  ????K +A denotes five-letter words ending in K containing A.
  • -[?] : Cannot contain [?] ????K -E denotes five-letter words ending in K without E.

Patterns usually will contain a couple of these elements; often to get around the issue of plurals that we discovered in our first game we’ll add the restriction -*S to remove all words that end in S from the list.  (Perhaps a –P wildcard could be invented to remove plurals but keep other words that end in S that are legit like abyss?)  The ideal number of words on the list to wind up with is between 45-75 for two players and 65-100 for three players.  We’ve yet to patternfill with four people, but conceivably you could play the game with as many people as you’d like.

There is one other, perhaps glaring problem with this game, and that is that it’s Lexpert-dependent and can’t be played without the program.  There’s not much I can say to defend it: it is Lexpert-dependent.  Lisa suggested that perhaps I should put some lists together, edit out the obscure words (what is LIPIN, and what is it doing in my ?I?I? list?), and create a Flash game, and that’s actually an excellent idea… if there’s enough lists to make it worthwhile.  The other issue I see is that doing an exercise like this will group the words that fit the pattern together in one’s mind, so I bet that a player’s score will increase markedly when presented with the same pattern multiple times.  This means that the game has practically no replay value (to me).

I’ve left a few patterns for the reader here.  If you’re filling them by yourself, in parenthesis are goal numbers of words to try to come up with.  If you get more than the goal number, you’re doing pretty well. For solo play, I don’t think a time limit should be observed.

Cylinder-related puzzle!

One of the most important parts of the Cylinder as I have presented it is coming up with the goal words and the start.  A logical question would be, can you find five words that are all pairwise five links apart, that is, can we find five words that use 25 different letters?  I wonder if Google has an answer for this… the last time I checked, no one had done it, to my knowledge.  The question is difficult to generalize, because no other number of letters offers a comparable challenge.  Maybe I could say, can we find five six-letter words that use all 26 letters?  (This also sounds super tough to me.) 

But that’s not a puzzle, and I promised you a puzzle!  So here’s something you can think about.  Can you find six four-letter words that use 24 separate letters?  I was able to complete this challenge last year, and to my knowledge everyone to whom I’ve shown this puzzle has not been able to do it (I may be wrong about this).  But I know I’ve done it.  And I’ll let you think about it for a little bit; then I’ll post my solution as a comment to this entry in about a week.  The real challenge is finding the right word that uses the letter Y as the vowel.  You might try a feline… that’s all the help I’ll give.  Good luck.

Yesterday's Cylinder

So we sprung* a flat tire on the way back from Copeland, and in the car we completed a five-letter cylinder and then thereafter completed a six-letter cylinder, which I shall post hereafter.  I will leave the five-letter game, SPANK CREEP RINSE GNOME, starting with CAUSE, as a game for the reader if he might like to attempt to play a game.

*I have decided that the verb associated with a flat tire is “to spring.”  Is this right?  What do other people say?

The Transadditional Cylinder

I think it makes the most sense to just pick it up from the middle.  I was pretty much forced into creating this by Nelson when I taught him the wordplay exercise that follows.  As I see it right now, the plan is to, over time, introduce all of the games that have become part of my canon and note the totally unnecessary research that I’ve done in the past.

So, first, the promised game.  This game was in some way conceived from Mr. Coyle’s Transadditional Pyramid, which deserves its own entry and will get one later.  It began as an exercise in chaining five-letter words together: CRASH to SHARD to HARDY and so on.  So you’re allowed to change one letter and rearrange the remaining ones.  There’s no real restriction on making “cheap” changes like PORED to PORES, but I generally attempt to avoid them.  You’re never allowed to repeat a word that’s already appeared in the chain.

What you’ll find when you do this is that it goes on forever.  Which is neat.  But generally uninteresting from a gaming perspective.  So then (maybe it was Mike or Thom that came up with this) we decided that we would force certain words to be in the list.  The idea originally was to create a tug-of-war kind of game, where I would be trying to make one word and my opponent is trying to make another, and we’re using the same chain — but this doesn’t make sense even in theory, because keeping the letters of the opponent’s word out of the chain would be very simple.  To my knowledge a varient of this game that revolves around that concept has never been created.

What we instead have patented is the following process: Before beginning the game, the player decides upon five five-letter words (serious people play with six but I’ll phrase the rules in terms of five).  These words must differ from each other by at least three letters.  So you’re not allowed to use the words PARCH and CHARM as two of your five words.  (This winds up being quite a challenge in itself!)  Four of your words are the goal words; the fifth is your start.  You must create a chain that contains all four of the goal words beginning with your start word.  There is no score for the game; you assess your game when it is over by either deciding victory or otherwise.  I’m sure you could find the shortest path through them if you really wanted to, but that’s not really the point in my mind.  To this end I try to avoid erasing plays unless I see no other way to finish the game.

Here’s the game I played that I showed Nelson (circa 05.12.22).  Hopefully you can pick up on my notation very rapidly.
