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 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.

Set up two rows of 20 golf balls each, 5 yards apart, on sloped rough near the green. One row is on uphill, one on downhill. Place rows 5–30 yards from the hole.

Take 36 shots total: 18 from uphill row, 18 from downhill row.

On the uphill row, hit every third ball until you take 18 shots.

On the downhill row, do the same: hit every third ball until you take 18 shots.

Only balls that land and stop in a 6-foot wide target area, 5–15 feet from the hole, count as a success. Same target for both rows.

Count all balls that stop in the target area.

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

Set up two lines of balls (18 balls in each line) next to the green on sloped rough. One line is above feet level and one is below feet level.

Set each line 5 yards apart. Balls should be between 5 and 30 yards from the hole.

Hit 18 bump-and-run shots from the above feet line and 18 from the below feet line (36 total shots).

For each line, hit every third ball (leave two balls between each shot). Finish all shots in one line, then switch to the other.

Try to land and stop the ball inside a 6-foot circle around the hole.

Count a success for every ball that stays inside the target circle.

Add up all your shots that stopped inside the target circle, then enter your total score out of 36 shots in the app.

Put 40 balls in 8 lines of 5 balls each around the green. Lines should be about 1 yard/meter apart and placed 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole.

On the green, mark two circle zones around the hole: one with a 6-foot (2 meter) radius and another with a 15-foot (5 meter) radius.

Hit 36 bump-and-run shots—first 18 shots aiming for the small inner circle, then 18 shots aiming for the bigger outer circle.

Use any line of balls. Hit shots for the inner circle for 18 attempts, then switch to hitting shots for the outer circle for another 18 attempts. Change lines as wanted.

Count each ball that stops in the circle aimed for as a success.

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