Patented 8x8 Arimaa was heavily licensed, though it is arguably not a true CV (no king-like pieces). The one who licensed it in my opinion slowed the spread of what could have been an explosively popular board game, e.g. countless books, over-the-board clubs, by requiring permission to write/start such, instead restricting (online) play to one official website (when I looked there many years ago I saw number of logins [at least some being players] that were listed [low 100's, about what it is now?!]). Elsewhere there's approved equipment, and there are also apps sold, at least.

Ironically, the game was promoted as computer-resistant (compared to chess), but that claim did not last for two decades, even, and so maybe now the game is less played globally(??). I recall one Google search I did many years ago had the result 'They've fixed chess' (probably in reference to computers and/or that an Arimaa game cannot ever end in a draw). One other 'defect' uncovered is that in setting up a start position (done by each side), only a small few strategies are now thought clearly best, I've read somewhere.

The inventor restricted the power of any hardware that could be used to challenge humans in the contests on his website, but still a machine (program) eventually triumphed over the best humans in matches. Currently it seems clear no board game can ever be computer-resistant for long, especially with self-teaching programs.

P.S.: I don't know much about patents around the world, but once any game is out in the public domain (and does become quite popular - usually requiring promotion by inventor anyway?!), I would guess the horse has left the barn; if so, no risk-free way to make a big profit, as is normal.

edit: Public domain rules, at least in US, may be more complex nowadays than I guessed - here's a sub-wiki that may be only just a taste:

I fully agree.

Chances that people want to play a variant are very small. Chances they would want to pay for it next to zero.

There are two variants I know of that were patented. In the U.S.. (Patents do not automatically apply world wide.) In the U.S. you can pretty much patent anything; whether the patent is valid is to be determined in the court cases that challenge it. That makes them cheap; there only is a (yearly?) registration fee. In Europe it can take tens of thousands euros to do the due diligence get a patent approved. (And the result of this in case of a chess variant would most likely be that it gets rejected, for lack of novelty.) As far as I know both U.S. patents expired before anyone challenged them, because the inventors got tired of paying the fees.

To make sure there would be no legal issues for this website, there was a ban on using words that reminded of the variant in any posting here.

I am not sure how you could make money out of a chess variant. Unless it requires special equipment, which you sell. Patents are more suitable for protecting equipment than ideas. Chess variants typically only require a board and pieces, though. Boards can be made from cardboard and paper, and pretty much anything could be used as pieces. (A wide selection of high-quality unorthodox pieces is already commercially available, both in wood and plastic.) There is no way you could prevent people using these at home.

Of course you could set up an internet server where the variant could be played on-line. And ask a fee for regestering there. It seems a good way to make absolutely sure no one would ever want to play it, even in the extremely unlikely case that the variant would have the potential to become popular on its own merits.

I have a new chess variant idea. 
Before I send it across to you , I have a few questions:

1) If my variant idea becomes popular, is there any way I can get paid for it ?

2) Can chess variant idea be patented ? Can I apply for a patent before sending it to you ? How many chess variants in your site are patented ?

Kutasi Márton wrote on 2020-11-08 UTC

very well you guys are the proffesionals and if it makes the game easier then yes in the first two ranks can make the pawns move forward two


Greg Strong wrote on 2020-11-08 UTC

I dont quiet understand the second question though what do you mean by first rank? Sorry for my lack of knowladge.

Rank means row.  Squares a1, b1, c1, ... f1 are the first rank.  A pawn moves backwards on its first move - pawn on e2 moves to e1.  It is now on the first rank.  Can it move two spaces?  Personally, I would make the rule like this: "any pawn on the first or second rank can move two spaces."  Otherwise, players must remember which pawns have moved and which have not.


H. G. Muller wrote on 2020-11-08 UTC

Well, it is not "just like in original Chess", as in original Chess you can never go back. So there is ambiguity whether to interpret the FIDE rule for Pawn moves as a location-dependent move or as a one-time initial move. In many Chess variants where you can go back (e.g. Crazyhouse, where captured Pawns can be dropped back on 2nd rank) a Pawn that returns there will again be able to move two squares forward. The advantage of that is that you do not need any 'hidden game state', to remember which Pawns have already moved and which not; just looking at the position will tell you everything you have to know. (About the Pawns. Castling rights are of course an example of hidden game state that even occurs in orthodox Chess.)


Kutasi Márton wrote on 2020-11-08 UTC

oh i see im a moron no if you go back to your original post where your pawn started you cannot move two tiles forward only if its the pawn first move in the match just like in original chess

I dont quiet understand the second question though what do you mean by first rank? Sorry for my lack of knowladge.


H. G. Muller wrote on 2020-11-08 UTC

The question is this: if you start moving a Pawn 1 square forward, and on a later move let it step 1 square backward, so that it is again on the square where it started... Can it move forward 2 squares then? Or only 1?

And what if it moves to the first rank? How many steps forward can it then make?


Kutasi Márton wrote on 2020-11-08 UTC

well you can never make two spaces backwards only one as i said, even if there is two space you can only do one


Greg Strong wrote on 2020-11-07 UTC

You miss the part where you can make the aggrements if both sides feel if they can make the other side do something that would make them more advateges then before you can betray the other one also this action tooks one turn and the other need to execute the action in their turn and then you do the same what he wants to also you can betray him this up to you if you feel that you can trust him next time.

This could be placed in the notes, but this is not really a rule.  All you are really saying is that players can talk.  They could do this in Chess too.  But they do not have to do what they say they will do.

nyway yes this how i would have been able to do it more sorted out about the question, you cannot make a space backwards 2 tiles only one though im not so sure if its such a bug diffrents on the field though if you feel like that playing the game it can make a diffrance then im sure we can change it though i never played my self with that rule included

My question was not about moving two spaces backwards.  My question is when can you move two spaces forwards?  In chess, any pawn on the second rank can move two spaces.  But in this game, since they can go backwards, they can leave the second rank and still come back.

Greg Strong wrote on 2020-11-07 UTC

It is being reviewed. Thank you for your patience.

I will need to make significant changes to the text for clarity. First, let me make sure I understand the rules exactly. I think the game is the same as orthodox chess except for the following:

  1. There is no check, checkmate, or stalemate.
  2. If you capture the opponent’s king, you win immediately
  3. If you move your king to the last rank, you win immediately
  4. Pieces cannot capture, except: (a) a King can capture anything, and (b) anything can capture a King.
  5. Pawns can also move a single space backwards, but cannot capture anything backwards.

Does this look right?

Also, another question about the pawn. When can a pawn make a 2-space move? Any time it is on the second rank? (For example, it moves a space backward to the first rank, then a space forward to the second rank. Can it then make a 2-space move?)


Kutasi Márton wrote on 2020-11-07 UTC

so how should i know if its getting rewied?


Kutasi Márton wrote on 2020-10-31 UTC

also thank you for the fast checking i was not expecting such hospitality


Kutasi Márton wrote on 2020-10-31 UTC

straight back my friend they cant kill if they go back and only if there is space


Greg Strong wrote on 2020-10-31 UTC

The pawns are also can move backwards

How do they move backwards? One space backwards? Can they capture a king when moving backwards? Straight back or diagonally?


Greg Strong wrote on 2020-10-31 UTC

Sorry, I had trouble finding your submission. It is not showing on the editor page for some reason, but I was able to find it in the SQL database. I will take a look.

Fergus, any idea why this page does not show on the unreviewed submissions page? https://www.chessvariants.com/rules/cold-war-chess


Kutasi Márton wrote on 2020-10-31 UTC

i have an unpublished subbmission and im asking if this is where i need to alert the staff or if that date is the one when it will be rewied


Greg Strong wrote on 2020-10-30 UTC

Posting here is fine, but I do not see any submissions from you


Kutasi Márton wrote on 2020-10-30 UTC

where am i supposed the alert that my chess varaint is ready in here, or where, cuz it said that im supposed to alert you guys


Fergus Duniho wrote on 2020-05-19 UTC

Okay, I did that.


H. G. Muller wrote on 2020-05-19 UTC

OK, too bad. But you are right, the large Shogi variants are a bit extreme in every way, and we probably won't encounter many other cases. It would indeed help me a lot if you could unpack the archive in MSmakadaidaishogi, even with 20 at the time it would be a lot of work to get them all there.

The archive is at http://hgm.nubati.net/2kanji.tar.gz .

Thanks!


Fergus Duniho wrote on 2020-05-19 UTC

H.G., Since you're probably the only one who needs to upload huge numbers of graphics, it may be easier for me to manually unpack an archive for you after you upload it. Just let me know where it is and what it's called.


Fergus Duniho wrote on 2020-05-19 UTC

PHP has max_file_uploads set to 20, and even though I've tried changing this in php.ini, it hasn't made a difference. I made sure it was the correct php.ini file. I stopped and restarted apache. And I even set a value for suhosin.upload.max_uploads, which I found a recommendation to do. But when I run phpinfo(), it still reports that max_file_uploads is 20, and that's all it lets me upload at one time.
