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

Set up two lines of 18 golf balls each on a sloped fairway near the green: one line on the uphill slope, one line on the downhill slope. Balls should be spaced 5 yards apart, between 5 and 30 yards from the hole.

Place 3 target zones on the green in a row, 6 feet apart. Call them Zone 1 (closest), Zone 2 (middle), and Zone 3 (farthest).

Hit 36 total bump-and-run shots: 18 from the uphill line, 18 from the downhill line.

From the uphill line, hit 6 shots to each zone (6 to Zone 1, 6 to Zone 2, 6 to Zone 3). Always hit every third ball, skipping two balls between shots.

For the downhill line, repeat the process: 6 shots to each zone, using every third ball.

Count a success each time a ball stops inside the intended target zone.

When all 36 shots are done, record how many balls landed in the correct zone, out of 36 attempts, 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.

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.

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

Put 36 golf balls into 2 piles of 18 balls each. One pile goes next to the edge of the green, and the other pile goes 5 yards/meters from the edge.

Mark 3 target zones on the green in a line. Each zone is about 4 feet wide, and the zones are 4 feet apart.

Hit 36 bump-and-run shots total. Aim 12 shots for each target zone, one zone at a time.

Start with the pile closest to the green. Hit 12 shots at Zone 1, then 6 shots at Zone

Go to the pile 5 yards/meters away. Hit 6 more shots at Zone 2, then 12 shots at Zone

Count each ball that lands and stops inside the correct zone as a success.

Add up the number of successful shots out of 36 attempts 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

Keep ball positions and distances the same for the whole test.

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

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

Place a bucket of balls next to the green with 2 straight lines of 20 balls arranged perpendicular to each other.

Space the lines 5 to 10 yards/meters apart, with each ball about 1 foot (30 cm) apart in each line.

Mark two circles on the green: an inner circle with a 6-foot (2 m) radius and an outer circle with a 15-foot (5 m) radius around the hole.

Hit 36 bump-and-run shots in 2 sets of 18 shots, switching between the two lines.

Hit 3 to 5 shots from one line, then switch to the other line, until all 36 balls are played.

Try to land balls in the circles: inside the inner circle is best, inside the outer circle is okay.

Count how many balls stopped inside the outer circle (including the inner circle), and enter your score in the app out of 36 attempts.
