Is there a Linux version of EclipseCrossword?
There is no version of EclipseCrossword for Linux computers. However, multiple people have reported that they’ve successfully gotten EclipseCrossword to run under the Wine emulator.
EclipseCrossword should also of course work just fine in a Windows virtual machine. And, web pages that you create on your Windows computer with EclipseCrossword can be played on a Linux PC in any modern browser.
