Thread the needle: roll your Bump'n'Run to tap-in range

Make 10 piles of 4 balls (40 balls) in two lines, crossing each other near the green, 1 to 10 yards from the green and 5 to 30 yards from the hole. Keep piles 2 yards apart, lines 5 to 10 yards apart.

On the green, use string or tees to mark two circles around the hole: one with a 6-foot radius (inner), the other with a 15-foot radius (outer).

Use only 36 balls (9 piles of 4) for this test.

Split the 36 shots into two groups of

For the first 18 shots, try to land the ball inside the small circle.

For the next 18 shots, try to land the ball inside the big circle but outside the small circle.

Play bump-and-run shots by hitting from different piles, one after the other, keeping the same setup and order.

Count as a success if the ball stops in the correct circle. If not, it is a miss.

Count how many balls finished where they should in both circles. Enter your score in the app, out of 36 attempts.

Set up 3 target zones on the green, called Zone 1, Zone 2, and Zone

Space them about 6 feet (2 meters) apart in a straight line.

Place your ball at the same spot on the fairway for every shot.

Hit 36 bump-and-run shots, with 12 shots aimed at each zone.

Hit 12 shots aiming for Zone

Hit 12 shots aiming for Zone

Hit 12 shots aiming for Zone

Each ball that stops inside the correct zone counts as a success.

When all shots are done, count how many were successful and enter your total number of successful shots out of 36 attempts.

Place two straight lines of 18 golf balls each on flat ground near the green.

Space the lines 5 yards apart and put them 5 to 30 yards from the hole.

Hit 36 bump-and-run shots.

In the first line, hit every third ball, skipping the two in between.

At the end of the first line, switch to the second line and do the same. Alternate lines until all 36 shots are hit.

Place three target zones on the green in a line.

For the first 12 shots, aim for the closest target zone.

For the next 12 shots, aim for the middle zone.

For the last 12 shots, aim for the farthest zone.

Count each shot that lands and stops in the correct zone as a success.

After 36 shots, total your number of successful shots out of 36 and enter your score in the app.

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.

Set up two lines of balls next to the green on a slope. Each line has 18 balls, 5 yards apart, between 5 and 30 yards from the hole.

One line has balls above foot level, the other line has balls below foot level.

There are two groups: 18 shots from balls above feet, and 18 shots from balls below feet.

For each group, hit every third ball in the line until you hit all

Aim each shot to land and stop in a target zone on the green, 5 to 10 yards from the hole.

First, hit all 18 balls from above feet, then all 18 from below feet.

Count each ball that stops in the target zone as a success.

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

Make two piles of 18 golf balls near the green: one pile has balls above foot level, one pile has balls below foot level.

Mark three landing zones in a line on the green's edge, about 5 feet apart (Zone A, Zone B, Zone C).

Hit 18 shots from the above-feet pile and 18 shots from the below-feet pile, for a total of 36 shots.

For each pile, hit 6 balls to Zone A, 6 balls to Zone B, and 6 balls to Zone C.

Count how many balls landed in the correct zone.

Arrange 10 piles of balls in two lines, with 5 piles in each line. Lines are 3 yards/meters apart; piles are 4 yards/meters apart in each line.

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

On the green, make two target circles with string or tees: an inner circle with a 6-foot/2-meter radius, and an outer circle with a 15-foot/5-meter radius.

Hit 36 bump-and-run shots: 18 shots at the inner circle, 18 shots at the outer circle.

Pick a ball pile and hit a bump-and-run shot to the target circle.

After 18 shots at one circle, switch and do 18 shots at the other circle.

Count every shot that stops inside the target circle as a success.

Add up your successful shots out of 36 in the app.

Set up 10 piles of balls in two lines that cross each other. Put 5 piles in each line. Leave space between all piles and lines.

Put the piles 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

On the green, mark two big circles around the hole. Make the first circle 6 feet (2 meters) out from the hole, and the second circle 15 feet (5 meters) out from the hole.

There are 36 shots total. Split them into 3 groups of 12 shots.

First 12 shots: try to stop the ball inside the small (inner) circle. Next 12: try to stop the ball inside the big (outer) circle but outside the small circle. Last 12: try to keep the ball anywhere on the green.

Hit one ball from each pile. Keep moving around the piles any way until all 36 shots are done using the right target for each group.

Count how many balls land in the right place for each group: inside the small circle for the first 12, in the big circle but outside the small one for the next 12, and anywhere on the green for the last
