Can't Stop is a push-your-luck style dice game designed by Sid Sackson in 1980. I've found it to be fun on BoardGameArena.
I wrote my own version for hack-a-day. You can play online. The source code is on github.
I'm pretty happy with this one. I didn't get to online play or even AI opponents, but you can play on your own or against friends in the room.
