I have little coding experience. Although I am somewhat proficient with art both traditional and digital.
Here is an interesting bitcoin game.

The sister site is:

Ive seen really good ideas that failed not because they weren't fun or sustainable but because they didn't get as popular. Great example:

Here are two other games that still exist.

http://chopcoin.io/   Skill based gambling game.
