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 4 lines of 9 balls each, with balls 1 foot apart.

Place the lines on grass, 1 to 10 yards from the green, 5 yards between lines.

Mark two circles on the green around the hole: one with a 6-foot radius, another with a 15-foot radius.

Hit 36 shots, in two groups of 18 shots.

For the first 18 shots, aim for the small circle. For the next 18 shots, aim for the big circle.

Hit balls in order from any line, switch lines as wanted.

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

After 36 shots, count how many hit their target circles and enter your score in the app out of 36 attempts.

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
