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

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.

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.

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.

Prepare 36 balls and make 4 piles of 9 balls each.

Put each pile in a different spot, 1 to 10 yards from the green and 5 to 30 yards from the hole.

Mark 4 areas on the green using string or tees, each area should be about 6 feet across.

Hit 36 bump-n-run shots, trying to land 9 balls in each area.

Start from one pile, aim at one area, and hit all 9 balls. Move to the next pile and area.

Keep going until all 36 shots are done, 9 shots per area.

Count how many balls stopped in the target area each time.

After all 36 shots, enter how many successes out of 36 in the app.

Scatter 40 balls into 8 piles of 5 balls each, between 1 and 10 yards from the green and 5 to 30 yards from the hole.

Mark 3 targets on the green, about 6 feet apart in a line.

Hit 36 bump-and-run shots.

Aim 12 shots at each of the 3 targets.

Hit 12 shots at the first target, then 12 at the second, then 12 at the third.

Count shots that stop inside 10 feet of the target as successful.

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

Get 36 balls. Split them into 3 piles of 12 balls.

Make 3 zones on the green with sticks or string. Each zone is 6 feet apart in a line.

On the grass, put each pile of balls at random spots 1 to 10 yards from the green and 5 to 30 yards from the hole. Each pile matches a zone.

Hit 12 shots from the first pile, try to land in the first zone.

Hit 12 shots from the second pile, try to land in the second zone.

Hit 12 shots from the last pile, try to land in the third zone.

Count how many balls land and stop in each zone.
