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

Pick two random spots 5-20 yards from the hole and place two piles of balls. Make spots and surfaces random but similar.

Make two circles on the green with string or tees: one circle 6 feet from the hole, one circle 15 feet from the hole.

Hit 36 flop shots: 18 shots at the small circle, 18 shots at the big circle.

At the first pile, hit 9 balls at the small circle, then 9 at the big circle.

At the second pile, again hit 9 at the small circle, then 9 at the big circle.

Count balls that stop inside the small circle as birdie. Count balls in the big circle (but outside small) as par.

Add up all balls that stayed in both circles. Enter score in the app, out of 36 attempts.

Arrange 40 balls into 10 piles of 4 balls each. Set the piles in 2 lines that cross each other, with 5 piles in each line, about 2 meters apart.

Place the piles on grass 5 to 20 meters from the hole, not on the green.

On the green, use string or markers to divide a 10-foot (3 meters) circle around the hole into 4 equal parts.

Hit 36 flop shots, 9 shots for each quadrant, trying to stop the ball inside each part.

Take turns hitting from different piles, aiming for the set part each time.

If the ball stops in the right part, count it as a success.

After all 36 shots, count the total successes and enter the number out of 36 in the app.

Place two ball markers on the green, about 10 feet apart.

Choose a spot on the uphill slope, 5 to 20 yards from the hole. Use this spot every time for the test.

Hit 18 flop shots from this spot. Aim at the targets, switching every 3 shots between them until all 18 shots are done.

Move to a spot on the downhill slope, 5 to 20 yards from the hole. Use this spot every time for these shots.

Hit 18 flop shots from the downhill spot. Switch targets every 3 shots until all 18 are done.

Count shots that stop within 3 feet of the marker as successful.

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