After two years of wait, the first two games of the developer DanLab Games (http://www.danlabgames.com/) are now available on MorphOS.
The first one is Marble Solitarus, a mind game, and the second one is Videp Poker Solitarus, a... video poker game.
You need MorphOS 1.x, 3D and SDL libraries to run these games.
Marble Solitarus and Video Poker Solitarus are freeware and downloadable on the Obligement's website :
