You can match numbers that are the same or add up to 10 if they're the next visible item in any direction or the last item of a line to the first item of the line below it. Space- double numbers (5 doubles) down/up keys show the next rows. Loosing- if you double 5 times but can no longer match a number you lose Winning- Match every number!
Inspired by offline games as well as many other of my good games.
