Not sure if this is helpful or not, but if it were me I'd make a Board class.  One of the methods would be the code to populate itself with random numbers.  You can then store all instances in an array.

This makes the code pretty simple. To fill all boards with random numbers, just 'boards.each{|b| b.populate}'
