Larger Toroidal Go games and GoBans with shapes other than squares.
  • Sighris at 2015-12-03

    If you are interested in playing a larger Toroidal Go game, say 13x13, or 15x15, please let me know either by replying to this forum post, or send me an email or FaceBook message. My email is

    Also, if you are interested in playing Go on a shape other than a square, for example the cross on the Swiss flag, please let me know. Thanks, Sighris

    Also let me know if you would be interested in playing Go on a hexagonal or triangular grid instead of the traditional square grid.  In my limited experience with this the rules need to be modified slightly to make it work well, but it can be done. :)

    This might be of interest to you:

    I'm not particularly interested in experimenting with Go at this point, but there are a lot of cool variations out there. How would you plan to play on an irregular go board online?

  • Sighris at 2016-03-03

    Thanks mmKALLL ★…I find other variations of Go more interesting than Round-Go; because Round-Go is the same as Tube-Go, and if I am going to do that (connect two sides) I might as well go one more step and connect the other two sides and make the Tube into a Torus!!! lol  ….  As to how to play them, the plan is to do something like what LittleGolem has done for Toroidal-Go; create another GoBan shape that people want to play on, or at least willing to give it a try, and see how popular it becomes.  For example: or I'm interested in trying the 2nd one down (the cross) shown here: - or something like it (a symmetrical + shape) but bigger.

    BTW, as I mentioned in another thread: Another T-Go possibility is to add a shift/twist (literally) into the mapping of the surface such that on the 5x5 T-Go game with 25 intersections named:

    • E1 E2 E3 E4 E5
    • D1 D2 D3 D4 D5
    • C1 C2 C3 C4 C5
    • B1 B2 B3 B4 B5
    • A1 A2 A3 A4 A5

    “A1” would connect to “B5” (instead of A5); “B1”  would connect to “C5”; “C1” would connect to “D5”; and “E1” would connect to “A5” (instead of E5)….

    The above is a one unit shift/twist; but a 2 or more unit shift could also be done.

    Jos Dekker replied to me that “Yes I would play 13x13 T-Go, if LittleGolem offered it. " - So I'm going to send Richard a request.

  • eobllor ★ at 2018-10-24

    I'd probably give 13x13 T-Go a try too!

  • Sighris at 2018-10-25

    If you are interested in a larger T-Go game, either 13x13 or 15x15, please give it a vote here:

  • Malcolm Schonfield at 2018-11-01

    Sorry Sighris, I didn't feel like registering on bitbucket so I haven't voted.

    I would be happy to try t-Go on 13x13 and/or 15x15. I would also like to try twisted t-Go at some point. (Twisted t-Go is mentioned on SL.)

  • Sighris at 2019-08-25

    I'm still interested in a larger T-Go game!

    If you want to push this idea too check out:

     - &/or write something here!

  • Sighris at 2019-12-15

    I’m still interested in a larger T-Go game!!!

    If you want to help push this idea too, please check out:

     - and everybody have a wonderful end of 2019!

  • Sighris at 2019-12-15

    BTW, somebody recommended a 15x15 T-Go instead of 13x13… I think that is an even better idea.  Post your vote &/or ideas on larger T-Go games here:

     - Happy holidays!

    In the “infinity games not starting?” post in the general forum, Richard Malaschitz at 2020-02-18 wrote: “Algorithm was changed. Now is start a new round when every player play one game or less (as average). Originally it was 1.5 game later 2.0 games. ” So again I'm asking that an infinite 13x13 or 15x15 Toroidal-Go Tournament be started; that way those who want to play more (&/or bigger) T-Go games can join both tournaments (or just the bigger sized board tournament)! Great idea, right? LOL - I'm not giving up on this!!!! :D

  • Sighris at 2020-11-14

    OK, so now instead of an 11x11 T-Go “infinite tournament” we have a ladder. Cool.

     - Now can we get a 15x15 T-Go game? - and a ladder too?  It can be a “Happy New Year!” present to the T-Go fans!!!! :)

    Please post your vote &/or ideas on larger T-Go games here:

     - Happy holidays!  (again) - and stay safe!!! There is a global pandemic happening! Keep your guard up. Together we can protect each other and get through this together.

    Sighris on a crusade, man

    I wish I could help you out, 11x11 feels surprisingly large to me, but I'm just starting.

  • Sighris at 2020-12-04

    Yep metzgerism- it is totally worth a post every 4 or 5 months!

  • Malcolm Schonfield at 2021-07-20

    Today I learnt about Variant Go Server. It seems quite basic but it does let you play toroidal go on lots of different size boards  (all odd numbers from 5 to 25).

    Apart from toroidal go it also has some other variants; it looks pretty interesting.

  • Sighris at 2022-06-02

    Thanks Malcolm Schonfield for your 2021-07-20 share! I've been super-busy, but I'll check out the Variant Go Server someday! :)

  • Sighris at 2022-10-26

    I still have not yet had time to look at the “Variant Go Server” mentioned by Malcolm Schonfield over a year ago (above, on 2021-07-20). I forgot about it until now. :-/

    Anyway, since Richard Malaschitz added “Go variant 27x27” here on Little Golem - my favorite “Go variant” website, I want to give a bump to the idea/request that Richard Malaschitz add a 15x15 Toroidal-Go variant here also! It was pointed out by somebody in another thread that 15x15 makes more sense than 13x13 in at least three ways, and I agree, so that is my current push/ crusade… but I'd gladly play 13x13 T-Go if for any reason that was significantly easier to implement here, or if that was the more popular request.

    I hope to mention this idea in the large FaceBook Go Players Group in the next week or two.

  • ypercube ★ at 2022-10-26

    I concur. A 15x15 (or 17x17) Toroidal Go would be good addition.

    I'd even go further and propose a 16x16 Toroidal version instead!

  • richyfourtytwo ★ at 2022-10-27

    What, no tengen???? ;-)
