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

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.

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.

Divide 36 golf balls into 3 groups of 12 balls. Put each group in the rough near the green.

On the green, mark 3 target zones about 15 feet from the rough.

Hit bump-and-run shots, aiming for each of the 3 zones in order. Hit 12 shots at zone 1, 12 at zone 2, and 12 at zone

Each ball that lands and stops inside its target zone counts as a success.

After all 36 shots, count how many landed in the correct zones and enter the total score out of 36 in the app.

Place 18 balls in a row on the fairway. Place another 18 balls in a row 5 yards away from the first row.

Label one row “Above Feet” and the other row “Below Feet” according to the slope.

Divide each row into 3 zones by distance: Zone 1 (5–13 yards), Zone 2 (14–21 yards), Zone 3 (22–30 yards), with 6 balls in each zone.

Hit all 36 balls: start with all balls in Zone 1, then all balls in Zone 2, then all balls in Zone

Take turns hitting every third ball from one row, then switch to the other row and do the same.

Try to stop each ball as close as possible to the hole.

Count each ball that stops within 3 feet of the hole as a success.

When finished with all 36 shots, record the number of successful shots out of 36 in the app.
