Nowadays this is the only place for playing Unlur.

GoRilla is a game editor by Dariusz Stachowski for the analysis and play of games of Go, Othello/Reversi, Hex, Unlur and Havannah. It is available for download from this web page. I very much enjoyed writing it and I hope that you will find it useful. I do know that there are game editors already available for Go, Othello/Reversi and Hex. My objective was to create a cost free product that would stand alongside the existing editors and would offer some original functionality. Also to make the games of Unlur and Havannah more widely known.
Gamedit is an Unlur editor by Pascal "Skal" Grossé. Gamedit is a program that can be used to create, load, save and edit
board games. While many games could be added in the future, for now
Gamedit mainly focuses on hexagonal board games. As Gamedit is still
beta software, the only available game is Unlur.
