I like your example so I started reading.

if for each wins in your example their was two conditions I could then
chain them together with an and. Awesome thanks.

So following your example where wins = [1,3] ( still not sure why ruby
doesn't have a multiple case select) can I use "and" "or"

If wins = 1 puts "for option 1 x = A_value and y = B_value"
    and or
If wins = 2 puts "for option 2 x = A_value and y = B_value"
    and or
If wins = 3 puts "for option 3 x = A_value and y = B_value"
    and or
If wins = 4 puts "for option 2 x = A_value and y = B_value"
else puts " There were no valid options"
