What is 1g0:
- SGF viewer / editor working in most browsers (pure HTML/JavaScript).
- 1g0 works on phones too (iOS & Android).
- You can import, study, and export games, and sync your games with Dropbox - so you can start your study on your home PC, then continue it using your smartphone while riding your commuting train, etc.
- 1g0 can sync games from KGS, OGS, DGS, and LitteGolem.

Of course, many improvements are needed, and many others would be a great addition. Please drop a note about which you want the most.
Thank you for any feedback.

Hi kubicle,

Thanks.

Suggestions:
- When the user takes against the bot ( as )
the "current" move marker looks like a stone ( even for black! )
so it's very confusing. Please fix the current move marker
so it's neither B nor W.

- The lines on 19x19 are very blurry and not clear.
Please fix the lines ( especially on a very small phone screen )

Thanks.

Hi EdLee,
Thanks a lot for feedback!
Could you tell me what kind of phone and which browser you are using?
About blurry lines, what is the screen resolution of your phone?
Thanks!

Hi kubicle,

iPhone 5, Safari:
The current move at S12 is , but the marker looks white:
full screenshot as shown:

Hi EdLee, thank you very much for the screenshot, it does look like something goes wrong with line drawing.
I only have an iPhone6 at hand to test it here but will try and see.

Update: OK there are 2 improvements I am working on which should fix this:

- handle retina displays so image appear neater even when they are on a small retina screen (like the iPhone 5 one). This will improve rendering on many phones, actually.

- use a proportional thickness to draw "marks" on stones (like the circle mark you are talking about). So if the board is on a small screen, the marks will be smaller, but also thinner.

Both of these will be included in release 0.2.23 - it will be in preview next week unless I run under a bus...

OK, it took much longer than expected, sorry about that.

EdLee and whoever is interested, would you like to check the preview version for me and let me know if you notice issues?

Here is the link:
https://ig0.herokuapp.com/?version=preview

Changes in this preview version:
- Responsive display now handles landscape mode and dynamic resize, so resizing your browser works better. On phones, landscape mode is experimental at this point.
- Retina screens (phones/tablets) handled much better.

Thanks!

The bots are too weak

Hi kubicle,

Thanks for improving the lines and the current-move circle.
They look much better now.

On a touch-screen device ( especially on a small screen ),
it would help tremendously to have either a magnifying glass feature or a confirm-move feature, or both.

I know I can use gesture to zoom in a section of the board, and that helps. But a "real" magnifying glass feature, like in SmartGo and iOS Pandanet, would be very helpful -- it's probably non-trivial to implement this nicely.

I don't recall changing any settings on the appearance, but suddenly the board switched from a "shin-kaya" light wood to a red wood ! Screenshot:

Yep, the bots were coded by me - they are rarely looking farther than the current move.
I think they are still OK for beginners to learn the game rules by try and fail.

If you are looking for a good bot I recommend Crazy Stone, for which there is also a free version (for Android at least) :

Hi kubicle,

The current theme names may be "fun" for software people:For a wider audience, maybe a more traditional spelling ?
{ Café au lait, Neon black, Bottle green } ?
( Car companies are quite creative with their adjectives. )
{ Tatooine (copyright issue ), Obsidian Black, Emerald Green }

Glad you like it better!

About zoom:
Did you try "holding" your finger on the screen longer? The stone should appear a bit above your finger and you can move it around before deciding the final spot.
Maybe you tried this already and would still prefer a zoom+unzoom feature. I never liked this zoom+unzoom myself, which is why I wanted something different.
I tried Pandanet recently and agree that they did a good job on it, though...
And yes, it is a bit of work to get a good/natural zoom+unzoom feature...

About wood texture:
It is randomly generated (not exactly random but you have a hundred variations right now). If you don't like the current color, each "reload" of the page might select another wood pattern. Stones change too but it is harder to notice

Hi kubicle,- Take a small screen device (say, iPhone5) ;
- Landscape mode ;
- Try to use this hold-method to play on D4. Lower left corner -- I couldn't do it.

Yes, I much much prefer the SmartGo or Pandanet zoom & un-zoom for not only small screens, but for iPads as well.

Thanks.

Indeed...
I would recommend using a phone in portrait mode, the UI was originally designed for it. As I wrote above, I consider it experimental for phones, and might conclude later that it does not bring anything (but frustration for players), in which case it should just be disabled.

Any plans to upgrade the AI ?

Hi kubicle,

How to toggle Alive/Dead stones for scoring ?

This needs to be improved indeed.
Created a trello ticket at https://trello.com/b/6J1KT4mP/1g0
Thanks!

I plan to improve it for my own fun of writing it, so don't expect it before long... And it will never be better than most up to date bots out there.

I copied the link to Crazystone above, even their free app is quite nice and strong.

Hello everybody,

Version 0.2.25 finally reached prod, with:
- UI: nicer switch between color themes (thanks EdLee for suggestion) + help tooltips.
- Proper handling of languages other than English (allows future translations).
- Fixed public link in Export dialog: can be selected for copy/paste.
- Responsive display now handles landscape mode and dynamic resize, so resizing your browser works better. On phones, landscape mode is experimental at this point.
- Retina screens (phones/tablets) handled much better.


And to give a good news after this late delivery, the next preview version (0.30.0) is already also available today.

Here is the link:
https://ig0.herokuapp.com/?version=preview

Most important change in 0.3.0 is the comment viewing/editing!

EdLee and whoever is interested, would you like to check the preview version for me and let me know if you notice issues?
