Putt put golf is an amusing sport that can increase your putting skills (as the name implies). But to improve your drive, your only option is to repeatedly play the game and move the ball closer to a pin. Relatively easy. What you need is obstacles to give you some more critical thinking skills that
translate to better driving skills.
Exhibit A: A full size golf course, standard yardage, greens, hazards, etc.
Exhibit B: The green on the 1st is encased in a bamboo cage, holes of which are about 20cm.
Exhibit C: A full size windmill, smack in the middle of the 3rd fairway. Either go through it or WAAAAAY over it.
Exhibit D: 4th green with an undulating surface (static or dynamic, your choice). Or perhaps it has a raised labyrinthine pattern in it that you can either power putt over or let your ball travel through.
Exhibit E: Ball ramps to the 6th tee, provided you can land the ball on the platform 5 yards in the air. On success, the ball will roll all the way to the hole, triggering whatzits, whirligigs, wet sprockets and widgets.
Exhibit F: Fairway on the 7th is hilly. Extremely hilly. Clear the peaks or your ball rolls back into the valley of darkness.
Exhibit G: Gigantic oscillating fans on the 9th fairway. If you're lucky, countering winds will keep the ball straight. Or maybe it will correct your slice. Or it could blow your ball onto the M4.
Etc, etc, ad naseum pro bono senator valorum.
