The 1.4 version of Jacqueline for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The actual developer of this free Mac application is InforMatrix GmbH.
From the developer:
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.
