Play an 18-hole under-par putting game
A putting practice game uses 5, 10, 15, 20, 25, and 30 feet, with three balls at each distance for 18 putts. Score it against par and try to finish under par - you have three putts at five feet so you should make at least one or two of those, and the rule is don't three-putt. Keep repeating the full round until you shoot under par.
