Neverball and Neverputt are two cool cross-platform open source games. Neverputt is a classic 3D golf game which has been done a few billion times. Neverball is a bit more original – it involves tilting the board. Actually, Neverball makes me feel a bit sick when I play it

There are 75 levels for Neverball and 62 for Neverputt so you probably won’t run out of levels any time soon. It’s a nice game to fill in the spare few minutes you have.

Other cool free, open source games I’ve covered before:

• GlTron
• Battle of Wesnoth
• Wolfenstein: Enemy Territory
• Penguin Planet Racer
