iOS Universal Games
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 (http://fuego.sf.net/). 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 (http://littlego.herzbube.ch/) 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.

Version 1.3.1 is a bugfix release that contains only one change, an important fix for a long-standing bug that sometimes caused ko detection to fail when an old board position was viewed (#307).
This was the root cause for the dreaded alert message "Your move was rejected by Fuego", which must have popped up on quite a few people's devices, but which I had never been able to reproduce despite the bug reports that were kindly sent to me by some of the most patient users. Yesterday, however, I received a report that finally gave me a reproducible case which allowed me to pinpoint and fix the coding error. Many thanks to everybody who sent bug reports, but especially to Manuel Braun for submitting the crucial last bug report.
