Risus

The 20th Anniversary edition of one of the world's first free RPGs (still free, always and forever). For some, Risus is a handy “emergency” RPG for spur-of-the-moment one-shots and rapid character creation. For others, it’s a reliable campaign system supporting years of play. For others still, it’s a strange little pamphlet with stick figures. No matter what you think it is, there's no wrong way to play.

Excerpt: 

Whenever anybody wants to do anything, and nobody's actively opposing it, and the GM doesn't think success would be automatic, the player rolls dice. If the total rolled beats (equals or exceeds) the Target Number set by the GM, success! If not, failure! Target numbers follow this scale:

5: A cinch. A challenge for a schmuck. Routine for a pro.
10: A challenge for a professional.
15: An Heroic challenge. For really inventive or tricky stunts.
20: A challenge for a Master. Nearly superhuman difficulty.
30: You've got to be kidding. Actual superhuman difficulty.
