Up-and-down contest: how many can you save in a row?

In a sand bunker, make two straight lines of golf balls. Put 18 balls in each line, spaced 1 foot apart. Lines should be 5 to 10 yards apart.

On the green, mark two circles around the hole: one with a 6-foot radius and another with a 15-foot radius.

Stand in the bunker 20 to 40 yards from the hole.

Hit 9 shots from the first line, trying to land balls inside the 6-foot circle.

Hit 9 shots from the second line, trying to land balls inside the 15-foot circle but outside the 6-foot circle.

Do steps 4 and 5 two more times, switching lines and targets, until you hit 36 shots total.

Count how many balls stopped inside the 6-foot circle and the 15-foot circle. Enter the total number of successful shots out of 36 attempts in the app.

Place 36 balls into 9 piles of 4 balls each. Space the piles in two crossing lines about 5 to 10 yards apart. Keep piles in each line about 2 yards apart. Make sure the piles are 20 to 40 yards from the hole.

On the green, make 9 stop zones with buckets, tees, or string. Keep zones clear and not overlapping.

Hit 36 sand shots, trying to stop 4 balls in each stop zone.

Hit 4 shots from the first pile to the first stop zone. Move to the next pile and aim at the next zone.

Keep going until you finish 36 shots, 4 to each zone.

Count each shot that stops in the right zone as one success.

Add the total number of successes out of 36 attempts and enter the score in the app.

Scatter 40 balls in the sand into 8 lines of 5 balls, with lines about 2 feet apart, anywhere 5 to 60 yards from the hole.

On the green, make two bullseye circles around the hole: one with a 6-foot radius, one with a 15-foot radius.

Hit 36 sand shots, divided into 3 groups of 12 shots.

For the first 12 shots, try to land the ball inside the 6-foot bullseye.

For the next 12 shots, try to land the ball between 6 and 15 feet from the hole.

For the last 12 shots, try to land the ball within 15 feet of the hole, including the 6-foot bullseye.

After all 36 shots, count how many balls stopped in each target area for each group, and enter your score in the app out of 36 attempts.

Arrange 10 piles of balls in two lines that cross at a right angle, with 5 piles in each line. Each pile has 3 or 4 balls.

Place the piles 3 yards or meters apart, between 20 and 40 yards or meters from the hole, in sand bunkers and not on the green.

On the green, mark two target circles around the hole: an inner circle with a 6-foot or 2-meter radius (bullseye) and an outer circle with a 15-foot or 5-meter radius (outer bullseye).

Take 36 sand shots in total. Do 18 shots aiming for the inner bullseye, then 18 shots for the outer bullseye (including the inner).

Start at any pile and hit one sand shot at a time, trying to land the ball in the target area.

After 18 shots at the inner bullseye, switch to the outer bullseye for the next 18 shots.

Count each ball that stops inside the targeted circle as a success. Balls outside the outer circle are misses.
