GFlyPool
A small pool table on the bar table, sixteen balls, real cushions and pockets. Every shot is simulated to rest before it is drawn, so the fly can try each pocket for each ball; with its brain on, the connectome chooses among the shots that are open and learns from what drops.
Rack them up
Eight-ball on a little table in the saloon, against one fly in a hat. Solids and stripes, the eight last. It loads the fly and the furniture once, about 4 MB.
