Go GridMaster (Baduk / Weiqi)

GridMaster provides a graphical user interface and artificial opponents for the game of Go (Igo, Baduk, Weiqi). This is the pro version (ad-free). It contains a full featured SGF reader/editor, a lite version of the 9x9 Olympic Champion Go program Steenvreter (it also plays larger boards), and a Go Text Protocol (GTP) interface to connect other gtp-compatible engine (so more opponents can be added). It can be used as a tool to play, study Joseki, solve Go problems, make diagrams, annotate games, etc.
If you are new to the game of Go, an introduction as well as some links to more information is included in the help.

Here's a non-exhaustive list of features:
- Full featured SGF reader/editor (perhaps the only Android app to support all properties in SGF4)
- Includes a fairly strong artificial opponent (Steenvreter lite, level configurable)
- Support for ARM and Intel cpu's
- Ability to add other bots such as GnuGo, Pachi, or your own GTP engine
- Tool for reviewing games (easy to rate moves/states, add comments, links, game info, etc.)
- Setup *any
* position (including illegal ones, e.g., for demonstration purposes)
- Quickly opens large SGF files such as Kogo's Joseki Dictionary
- Supports all rectangular board sizes up to 52x52
- Tips at start-up (can be turned off)
- Accurate stone placement even on small screens
- Correct wrong input by shifting stones
- Zoom in to show only some part of the board (by pinching)
- Zoom out to show the game tree
- Fast navigation through the game tree (button push+slide action)
- Auto-replay games at configurable rate (long-click forward to start).
- Collection support (i.e., multiple game trees in one file)
- Share option
- Export to image file
- Copy-paste variations/games (also between applications as sgf text)
- Configurable rules (Chinese / Japanese)
- Configurable timing (Absolute / Canadian / Japanese / Stopwatch)
- Configurable sound for stone placement & clock
- Various graphics options (configurable in settings)
- Full screen portrait & landscape modes
- Indicate last and/or next move
- Extensive help, includes an introduction to Go
- Optional debug tab shows GTP streams (the communication between GUI and engine), rules issues, and provides option to send gtp commands manually (double-tap to pop up dialog).

Before buying, try out the free version of GridMaster (https://play.google.com/store/apps/details?id=nl.tengen.gridmaster) which is currently identical except for the ads.

If something doesn't work, send me an email. Suggestions for improvement are always welcome.

Best Go game. Functionality excellent. Would be great to know if there is a manual to get the most out of it. Can't figure out how to solve problems or delete variations from game trees. I'm sure it's possible, just not intuitive.

Seems great, but only leaving 3 stars since the download of new engines does not seem to work (specifically leelazero). There also does not seem to be a log file or an error message to lookup. EDIT: Seems to be just new leelazero with the problem, old leelazeros install okay

Very competitive go engine, great interface, responsive developer. I mostly play it on 13x13. No chance really on 9x9 as 4d player.

Leela Zero on a phone! Woo hoo! Not the prettiest, and I don't find the editor very intuitive but perhaps it will grow on me.

I love this app. When my friend and i play on a board, we record our game with Gridmaster. I use it for practice a lot too.

Best Go client for your mobile device, period. The free version is identical to this one, but I wanted to support the developer because it is so well made. Absolutely worth the $3 price tag. The.coice of different AI engines is great, the interface is intuitive (game tree is innovative and very usable even on small devices), the graphics aren't flashy or distracting. This is a must for any Go player.

Great app for me as a beginner, having various levels of AI and a super nice interface for game review

Simply the best!

While it stomps me at even, I get a great game with a 9 stone handicap...and still mostly lose. That said, I love how I get my Go fix at any time on my phone. Awesome job! So awesome, I bought the app (upgrading from the free version).

This is installed on my e-reader. Nice competent AI, great interface for viewing games and commented SGFs. Recommended. Suggestion: option to use volume keys to advance & undo moves in locked games.
