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

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 10 piles of balls in two crossed lines. Each line has 5 piles, 3 yards/meters apart.

Put the piles 1 to 10 yards/meters from the green and 5 to 30 yards/meters from the hole, on the same type of grass.

Mark 3 target zones on or near the green, spaced far apart.

Hit 36 bump-and-run shots: 12 for each target zone.

Pick any pile and hit 12 balls, trying to land and stop the ball in the first target zone.

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

Keep the same ball setup for every shot. Don’t change ball position or lie in the pile.

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

At the end, enter the number of balls that stopped in the target zones out of 36.

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.
