Feel the green—leave every Bump'n'Run inside the safe zone

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.

Make two lines of 18 balls each, one foot apart, next to the green, in an L-shape.

Put 3 markers at the edge of the green, 6 feet apart, to make 3 landing zones in a row.

Hit 36 bump-and-run shots: 12 shots at each landing zone.

Switch between ball lines. For each zone, hit 3 shots from one line, then 3 shots from the other, until all 12 shots per zone are done.

Each time a ball stops in the right zone, count it as a successful shot.

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

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.
