Jacqueline Go is an implementation of the old asian strategy game of Go.
Try to surround empty fields and the stones of the enemy
by putting your stones on the board.
If a group of enemy stones is completely surrounded, it is removed from
the board. The player with more stones and more territory wins.
For experienced players, Jacqueline Go offers the following features:
- load and save SGF files
- edit game positions
- handicap stones
- can be used as a front end for other go programs (GTP)
- offers different boards
- supports English, German and Swiss German
