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

Put 2 rows of 20 golf balls each on flat grass near the green, 5 yards apart.

Make sure both rows are between 5 and 30 yards from the hole, and keep all balls on the fairway, not on the green.

Split the 36 shots into 3 groups of

First 12 shots, try to land the ball within 5 feet left of the hole.

Next 12 shots, try to land the ball within 5 feet right of the hole.

Last 12 shots, aim to land the ball in a 5-foot circle around the hole.

Hit every third ball from each row: start with one row (balls 1, 4, 7, etc.), then switch to the other row, and keep going until all 36 shots are done.

Count each ball that stops in the right target area as a success for that group.

When all 36 tries are finished, add the successful shots and enter your score in the app, out of 36.

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.

Set up 10 piles of balls in two lines. The lines are 3 yards/meters apart. Each pile in a line is 4 yards/meters apart.

Place the piles on grass 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

Make 9 stop zones on the green with buckets, string, or tees. Number the zones 1 to

Divide 36 tries into 9 groups of 4 shots. Each group tries for a different stop zone.

For each set of 4 shots, choose any pile and hit shots to the chosen stop zone.

After 4 shots at one zone, go to the next stop zone and do the same. Do this for all 9 zones.

Count every shot that stops in the right zone as a success.

Add up successes out of 36 tries and enter the score in the app.

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.

Hit 36 bump-and-run shots: 12 to zone 1, 12 to zone 2, 12 to zone

Use the first set of 12 balls for zone 1, the second set for zone 2, and the last set for zone

Get 36 balls. Split them into 3 piles of 12 balls.

Make 3 zones on the green with sticks or string. Each zone is 6 feet apart in a line.

On the grass, put each pile of balls at random spots 1 to 10 yards from the green and 5 to 30 yards from the hole. Each pile matches a zone.

Hit 12 shots from the first pile, try to land in the first zone.

Hit 12 shots from the second pile, try to land in the second zone.

Hit 12 shots from the last pile, try to land in the third zone.

Count how many balls land and stop in each zone.

Add up your total and enter your score in the app, out of 36 attempts.

Set up 10 piles of balls with 4 balls in each pile, in two lines 5 to 10 yards apart, and each pile 2 yards apart in its line.

Place 9 stop zones on the green using markers. Space them so each is easy to aim at.

Divide 36 shots into 9 groups of 4 shots.

Hit 4 shots at each stop zone. Hit from any pile, but keep ball setup the same.

After 4 shots to one zone, move to the next zone. Keep going until all 9 zones are done.

Count how many shots stop inside the target zone for each group.

Add up total successful shots. Enter score in the app, out of 36 attempts.

Set up 4 rows of 9 balls each, spaced 1 foot apart. Each row is 3 yards apart.

On the green, use strings or tees to mark 4 circles, each 6 feet wide.

Hit 9 balls at each circle, for a total of 36 shots.

Start at any row. Hit 9 balls at the first circle, then the next 9 at the second, and so on for all circles.

Keep the balls in the same place and aim at the target circle each time.

Count how many balls stop inside each circle after 9 shots.

Add up the number of balls that stopped inside the target circles out of 36, and enter score in the app, out of 36 attempts.
