Little Go is a free and open source iOS application that lets you play the game of Go on the iPhone or iPad. You can play against another human (on the same device), or against the computer. The computer player is powered by the open source software library Fuego ( The minimum requirement for running this version of Little Go is iOS 8.1.

- Board sizes between 7x7 and 19x19 (start a new game to change the board size)
- Let the computer player make a move for you
- Calculate the score at any time during the game (area scoring is the default, territory scoring can be selected at the start of a new game)
- Adjust the computer's playing strength and resign behaviour by selecting from a number of presets, or by fine-tuning advanced settings
- Play even games, or games with 2-9 handicap stones (fixed stone placement)
- Select from 5 pre-defined rulesets when you start a new game, or adjust game rules to your preference (komi, ko rule, area/territory scoring system, number of passes to end game, resume play by alternating/non-alternating play, four passes end game)
- View board positions for moves played earlier during the game (no support for game variations, though)
- Discard moves (aka "undo")
- Display move numbers and coordinate labels
- Zoom & scroll board
- Display player influence (aka territory statistics) for an estimate who owns an area
- Computer vs. computer game for entertainment
- Save & load games to/from the archive
- Use iTunes file sharing to transfer saved games to/from your iOS device
- Import/export game files from/to other apps on your device (e.g. Mail, DropBox)
- In-app user manual (text-only)
- Submit bug report email from inside the app (yes, this *is* a feature :-))
- For the technically inclined: Watch what happens behind the scenes when Little Go and Fuego talk to each other over the Go Text Protocol (GTP)

Your contribution in any form (coding, UI design, testing, bug reports, creating an app video preview, website design) is welcome - please contact me or visit the project website ( to find out more.

A note about the project state: Several years of development have gone into Little Go since its inception in January 2011. The app now has a feature set that is, I believe, quite nice :-) for a free program. My main focus will therefore lie on fixing any remaining bugs (of which I am sure there are plenty) and keeping the app running under future versions of iOS.

What’s New

Version 1.5.1

This is the Little Go bugfix release 1.5.1. It contains a fix for a bug that causes the app to crash during launch on iOS 9.x and below (#332). Thanks to Li Chen Ke and Dennis for reporting the issue.

The previous release was the Little Go feature release 1.5.0. It contains the following changes:

- Added a board setup mode (#276). When you start a new game, instead of beginning to play you can now switch to board setup mode. In this mode you can place black or white stones in any order and combination to set up the initial board before you begin to play moves. In addition to placing stones, you can select the side which is to play the first move. Read the "Board setup" section in the in-game manual for a detailed feature description.

- Fix for a memory leak in UnarchiveGameCommand (#331)

Technical changes
- Added an initial set of a few automated UI tests (#134)

Too hard for beginners.

I enjoy the game, but the computer is much to advanced for beginners, and the second I turn on a handicap the bot resigns on its first move. If there was some way to stop the bot from resigning, I would give it a 4/5, but as is the app is simply infuriating.

Edit: I found the setting to turn off AI resignation. It’s well hidden, but as promised I am changing my score to 4/5.

MUCH TOO HARD, not fun at all

Give up. You're going to lose. You were going to lose within the first few moves. Even with the engine on the weakest setting, you are going to lose badly, very quickly, every single time. It is not fun at all. Don't even bother playing. You lose. And in case there are some random chance you might accidentally win, don't worry, the computer gives itself seven points ahead of you, even though you don't get a handicap with extra pieces to start like you're supposed to. Or, if you find a very well hidden the setting that allows you to get a couple of extra pieces is a handicap for the other player, the very first time you take one of its pieces, it simply resigns. So, I hope you like losing, and losing badly, because that is all that's going to happen in this game. If you think having even the slightest chance of winning is fun, forget it, because it will quit the minute it thinks there's even a tiny chance you will win. You lose.

Developer Response ,

Thanks for your review. It mercilessly but truthfully points out what are probably the main shortcomings of the app: 1) The default profile is too strong for beginners. 2) The computer player does not always act as a human player would, this is especially obvious when it comes to resigning. 3) The app is too technical for the casual user. Although configuration options exist that allow the user to weaken the computer player down to a suitable playing strength and to change its resign behaviour, these options are not available at a single, easy tap, but must be found and explored by an investigative user. Although everything is documented in the in-app manual, reading the manual requires a significant amount of time.

Apart from point 1 there's not much I could or would change, though. Sorry for that, but you will have to find a different app that suits you better. A final word regarding komi and handicap: You can easily adjust those when you start a new game. Please take the time to have a look at the settings in the "New game" screen.

Great App

My favorite part about this app is how much you can customize & tweak. Overall, everything else about it is also pretty strong; display, UI, and even the manual is pretty clear/thorough. People whining about the AI being difficult don’t understand just how high the skill ceiling is for this board game, and even the weakest setting should still take some decent practice to overcome. Besides, if you’re constantly losing to the AI, then that’s a perfect opportunity to see what types of moves are being used to beat you — Look for patterns and adapt your strategy accordingly!!

To the developer(s): Very nice work. 5/5
