Looks to me like the variable matrix is nil. Looks like it is called form line
97.
I'm not familiar enough with controller_store or connection_store (are those
from WebSockets gem?) to know what to tell you. Did you put a debugger above
line 97 and try to figure out why
controller_store["gomoku_guess#{connection_store[:game].id}"] appears to be nil?

I would move nearly all of your domain logic code into domain objects ---
either model objects or plain-old-ruby-object (PORO) objects--- then write unit
tests covering the interactions between the controllers & domain objects. That
way you will have more isolated parts to work with so you can figure out where
the problem is.
