My favorite casual games to play on Linux

I love a good game that you can immerse yourself in for hours, but I don[he]#039[/he]t always have the luxury of ignoring daily tasks to disappear into a video game. Still, I do love a fun challenge from time to time, and two of my favourite applications to launch when my computer gets busy doing something that I need to wait on are games from the KDE Games package: KBlocks and Kolf.
