I am passionate gamer, really. During holidays, I do more gaming than anything else. My gaming experience spans many-many open-source and Linux games. I am pretty sure that, like me, many of you might have also tried these games.

Here is the list of my top 15 games (I wanted to cut it to top 10, but my favorites out numbered the list):

15. KBounce

This is a part of the KDEGames suite and is a very addictive game.
KBounce is a clone of the computer game JezzBall, developed as part of KDE. Following a lot of the original concepts of JezzBall, KBounce requires the user to adapt to its increasing difficulty by applying an array of critical thinking, intuitive thinking and reflexes.
