This week's weekend challenge #3 weekend challenge #3 seemed like a great opportunity to learn Ruby! Unfortunately, my workload and looming vacation did not cooperate. :( The puzzle will make forced moves automatically, but I was hoping to implement rules such as Naked Pairs before resorting to brute force.

Update: I'm looking for feedback on Ruby style (e.g. "avoid
andandoras they are confusing"), correct use of idioms and the standard library, code organization, etc. This is a Ruby learning exercise, so I want to avoid picking up bad habits early. Since I haven't implemented any brute-force or complex solving yet, performance isn't an issue.

I'm looking for feedback on Ruby style (e.g. "avoid and and or as they are confusing"), correct use of idioms and the standard library, code organization, etc. This is a Ruby learning exercise, so I want to avoid picking up bad habits early. Since I haven't implemented any brute-force or complex solving yet, performance isn't an issue.

Update: I'm looking for feedback on Ruby style (e.g. "avoid
andandoras they are confusing"), correct use of idioms and the standard library, code organization, etc. This is a Ruby learning exercise, so I want to avoid picking up bad habits early. Since I haven't implemented any brute-force or complex solving yet, performance isn't an issue.
