Thread the gap: precision Bump'n'Runs to a tight pin

Put 36 golf balls into 3 groups of 12 balls. Spread the groups around the green between 1 and 10 yards from the edge and 5 to 30 yards from the hole.

Mark 3 landing zones in a straight line at the edge of the green, each 6 feet (2 meters) apart.

Add your total successful shots and enter your score in the app out of 36 attempts.

Put 36 balls in 2 lines near the green. Each line has 18 balls about 1 foot apart.

Place the 2 lines so they cross each other like a plus sign, 5 to 10 yards apart.

Put 3 targets about 6 feet apart on the green.

Hit 12 shots at each target, for a total of 36 shots.

Start with one line and hit 12 shots trying to stop the ball within 10 feet of the first target.

Use the other line and hit 12 shots at the second target, same goal.

Hit 12 shots at the third target from either line, trying to keep within 10 feet.

Count each shot that stops within 10 feet of the target.

After 36 shots, write down your number of successful shots out of 36 attempts in the app.

Make two lines of 18 balls each, one foot apart, next to the green, in an L-shape.

Put 3 markers at the edge of the green, 6 feet apart, to make 3 landing zones in a row.

Hit 36 bump-and-run shots: 12 shots at each landing zone.

Switch between ball lines. For each zone, hit 3 shots from one line, then 3 shots from the other, until all 12 shots per zone are done.

Each time a ball stops in the right zone, count it as a successful shot.

After all 36 shots, add up your successful shots and enter your score in the app out of 36 attempts.

Place two lines of 18 balls each near the green. Balls are 1 foot apart. Lines are 5 to 10 yards apart.

On the green, make a circle around the hole (6 feet radius) and divide it into 4 equal quadrants with string or markers.

Hit 36 bump-and-run shots total, 9 shots at each quadrant.

For each set of 9 shots, aim to stop the ball inside one chosen quadrant.

Hit 4 or 5 shots in a row from one line, then switch to the other line and finish the 9 shots for that quadrant.

After 9 shots to one quadrant, move to the next quadrant and repeat the routine until all 4 quadrants have been used.

Count each ball that stops in the right quadrant as a success.

After all 36 shots, add up successful shots in the intended quadrants and enter score in the app, out of 36 attempts.

Arrange 40 balls into 10 piles with 4 balls in each pile. Set the piles in two lines that cross each other near the green. The two lines should be 6 yards apart. Each pile in a line is 2 yards from the next pile.

Pick 3 target flags on the green. Space the targets 6 feet apart in a line or triangle so each one can be aimed at.

Hit 36 bump-and-run shots, in 3 sets of 12 shots. For each set, aim all 12 shots at one of the target flags (Zone 1, Zone 2, Zone 3).

Start at any pile and try to hit the ball so it lands inside a 10-foot circle around the chosen target. Do this for 12 shots, then move to the next target and do it again, until all 36 shots are done.

Use different piles as you like for variety, but always set up the same way for each shot.

Count each shot that stops inside the 10-foot circle as a success.

After all shots, count total successes and enter score in the app, out of 36 attempts.
