Pick your spot and trust your swing—bunker aim challenge

Make two straight lines with 20 balls in each line. Each ball is about 1 foot apart. The two lines are 5 to 10 yards apart.

On the green, mark 9 stop zones using buckets, string, or tees. Keep the zones apart.

Hit 36 sand shots from the bunker. Try to stop the ball inside the zones.

Split the 36 shots into 9 groups. Each group has 4 shots.

For each group, hit 4 shots from one ball line at one stop zone.

After 4 shots, switch to the other ball line. Aim 4 shots at the next zone. Keep going back and forth until you finish all 9 zones.

Count how many balls stay in the zone they were aimed at.

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

Pick two different bunker spots, each 20 to 40 yards from the hole.

From each spot, hit 9 shots to Target A and 9 shots to Target B. Alternate every 3 shots.

Use the same setup and swing for all shots. Only change where you aim.

Set up 10 piles of balls in two rows with 5 piles in each row. Leave 3 yards (2 meters) between the rows, and 4 yards (4 meters) between piles in each row.

Put these piles in the sand area, 20 to 40 yards from the hole.

On the green, mark 4 equal circles using string or tees. Each circle has a 6-foot (2 meter) radius.

Hit 36 sand shots. Hit 9 shots at each of the 4 circles.

Start from any pile. Hit one ball at a time, aiming for the first circle.

After 9 shots at the first circle, move to the next circle and repeat until all 4 circles are used.

Count how many balls stop inside the correct circle.

When done, add the number of balls inside the circles, out of 36 attempts, and enter the score in the app.
