      Any updates on progress? Last update was December 2016, and the original delivery prediction of Feb 2017 was some time ago now. I guess it has turned out to be more work than originally thought!
      It would be good if you could write an update on how it's going, what your plans are for it.

      I never received my key... Any updates on dev?

    3. Chris Cantwell Creator on

      I resent keys, please let me know if you have still not received anything.

    4. Donald Bradley on

      I haven't received my steam key either. :(

    5. spectrumcat on

      I didn’t receive anything either :(

    6. Targo on

      Still waiting for any response either here or by private message

    7. Targo on

      I have not received anything either! Would you please advise?

    8. Chris Cantwell Creator on

      I've sent those who haven't gotten keys a personal message. If anyone else hasn't yet received a game key please message me. Thank you all for the support!

      Hi, I still haven't had my key :-(

    10. James Austin

      It's possible that it just got caught up in my spam filter back when it got sent out, since I wasn't looking for it because I didn't see that we'd gone live.

    11. Chris Cantwell Creator on

      Hey, sorry for any issues. I'll look into this right away

    12. James Austin

      Uh, actually, now it's being mentioned, I missed the notice that the game was going live and never had the key appear for me.

      I've not received my reward yet or is it not yet delivered?

    14. Chris Cantwell Creator on

      Hey, sorry for the late response. I caught a bug that has kept me down for a while. I'll look into it right now.

      I never received any of my rewards, including digital downloads and keys. The last email I have from this project is dated December 2016. I finally decided to visit this forum and see what was up. Looks like people are enjoying the game. I would like to as well. :)

    16. Chris Cantwell Creator on

      @Rachel I just left you a message. @JC Thanks! I'm glad you're enjoying the game!

      Today I finally signed up on Steam and used my alpha key to play in 2D. I can't post on the Steam discussion board because I don't have Guard enabled (I don't even know what that is) so I have come here to post the supportive comment that I wanted to post there.

      So: I'm having a blast. I find that the quantum moves add a risk-taking element that completely changes a game of chess for me. The current AI beat me consistently until I started using my quantum moves effectively (and slightly less often - quantum to get in position, regular move to capture, study board, repeat). I still only win when I take risks that pay off ... so still, not often ... but taking risks is one of the only advantages that I as a human have.

      For everyone tired of the standard openings: quantum-ing out BOTH KNIGHTS at the beginning makes that whole "control of the middle of the board" struggle really fun.

      3D made it much harder for me to see the board, or else I was familiar with 2D from the videos and twitching. 2D is also the mode in which I play regular chess online, so perfectly fine.

      Finally I would urge everyone to ignore the snarky "Is this dead" comments. In this world it's easy to snark and super challenging to actually build anything. Or as Teddy R once said (please read this thinking of all genders):

      "It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."

      Hey! Just wondering if the backer rewards have been sent out yet as I'm like an excited puppy by the letterbox each morning! Wishing you all a fab day :-)

    19. Zwerver on

      My apology's for not my delayed response. Yesterday I received my USB stick in good condition. Thank you very much!

    20. Chris Cantwell Creator on

      I'm so sorry! Please send an email to and we'll get it sorted out asap. If you could include a picture of the packaging that would be useful.

    21. Zwerver on

      This day my envelop with the Quantum Chess USB arrived, but unfortunately it was empty. A hole in the back suggests the USB was "lost" in transit leaving an empty envelop. How can we resolve this?

    22. Chris Cantwell Creator on

      I sent your keys through private messages. For anyone else who hasn't received a key yet, please check your email for anything from Backerkit. You can also log into your Backerkit account to access your digital downloads. If you have any trouble don't hesitate to drop me a message.

    23. Rob Macdonald on

      I still haven't gotten anything!

      ... nor have I received a key (originally thought it was because I was "pawn" level.

      I also haven't got my key

    26. Chris Cantwell Creator on

      You should have received an email with your code and instructions from Backerkit. I'll look into it. Sorry for the delay.

    27. Curtis

      Hello, I just read the last update and saw a couple months ago you said that $10 pledges would get their keys. I pledged $10, but have yet to get the key. How do I get my hands on it? Thanks for the info

    28. Chris Cantwell Creator on

      Hey Shek, sorry for the delayed response. I've been doing some major back end rework to speed up the engine significantly so it can support a smarter AI. I've already managed to cut the move generation memory overhead from 2.4 GB to 24 MB, but it still isn't enough. After a few moves at one level deeper search it starts taking 30-60 s per move. So working on some more optimization.

      Any news? I hope this isn't vaporware like most of the stuff on kickstarter...

      Question: I paid $10 to get the Pawn version. Should I have been sent a copy of the game or not?

    31. XryptiCipherX on

      I've donated on the Grand Master Pledge. I received the alpha key for steam and it has been working great. I uninstalled it to make some room for a couple of days and just now tried to reinstall. It won't grab the files from the server it seems. Then I just got your guys email saying beta key is ready to go soon. I haven't received the beta key tor steam yet. Thanks Chris!

    32. Chris Cantwell Creator on

      Hi Riccardo! The most recent key that was sent out was for the beta level backers, it is not the release key just yet. But don't worry, we're getting there soon.

      Riccardo Arpe on

      Hi, i didn't receive the steam key and i think i should have.

    34. Chris Cantwell Creator on

      It is yours to do with as you please :). You should join the discord chat, it is pretty active right now!

    35. Solensia on

      If we already have an Alpha Key, can we give the Beta Key away?

    36. Chris Cantwell Creator on

      All beta backers should have received a Steam key now. If you did not receive one and think you should have, let me know.

    37. Chris Cantwell Creator on

      Hey Solensia! Sorry for the delay. A lot is happening right now. I can't announce an exact date just yet, but be on the lookout for an update soon announcing the beta! And other rewards are in production.

    38. Solensia on

      Any update? I haven't heard anything for months.

    39. Chris Cantwell Creator on

      Let me look into that right now.

    40. Nick Shupe on

      Where is the alpha down load link on backer? I haven't gotten it for months?

    41. Chris Cantwell Creator on

      Hi Juan! Sorry, I wanted to post this link sooner but I was having some technical difficulties with discord. Here is a new link to try. They expire after 24 hours I believe.

    42. Juan Antonio Navarro Pérez on

      Finally got able to download the alpha on steam and play for a bit. I'm super confused about the game play! For example, how is it that sometimes I end up with just half a piece? I'm sure a lot of you have had ample discussions about the rules of the game and their implications, but is there a place where newcomers could see answers to common questions or ask if in case of doubt?

      I tried to follow the discord links below, but they don't seem to be working anymore.

    43. Elmar van Kordenoordt

      So, whilst there is a lively discussion on the Discord channel I thought I'd pop in here as well. So currently the alpha is on version 0.0.6044 how are you guys liking it so far?

    44. Chris Cantwell Creator on

      Yeah that is on the list to be fixed.

    45. Mc on

      Also I noticed the white(light) and black(dark) squares are reversed (compared to standard chess) - is this intentional? For example d1 in standard chess should be white (not black).

    46. Chris Cantwell Creator on

      You're welcome! And, thank you for your patience everyone.
      And yes, by all means report bugs. I'm taking bug emails at
      You can also join us in discord for a lively discussion of bugs.
      Thanks for the move list on that one. Great help.

    47. Mc on

      So alpha is out, cool! And thanks!
      Does it make sense to report problems at this stage, or shall we wait for beta? I tried game against AI and it stopped moving after I made the first quantum move in the following variantion:
      1. e2-e4 Ng8-f6 2. e4-e5 Nf6-d5 3.d2-d4 Nb8-c6 4.Ng1-f3 e7-e6 5.Bf1-d3 Bf8-b4 6.Bc1-d2 Bb4xd2 7.Nb1xd2 h7-h6 8.0-0 0-0 9.qQd1?e4
      And here the AI froze... Chicken :-).

    48. Chris Cantwell Creator on

      Thanks! I like them. I'll pass along the compliment.
