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

Split 36 balls into two groups of

Put one group at the uphill slope, and one group at the downhill slope, both in deep rough 5 to 20 yards from the hole.

On the green, make three target zones side by side, each about 3 feet wide and within 10 feet of the hole. Label them Zone 1 (left), Zone 2 (center), Zone 3 (right).

From the uphill position, hit 18 flop shots. Aim 6 balls in Zone 1, 6 in Zone 2, and 6 in Zone

From the downhill position, hit 18 flop shots. Aim 6 balls in Zone 1, 6 in Zone 2, and 6 in Zone

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

Enter the number of successes in the app, out of 36 attempts.

Divide 36 balls into 9 piles with 4 balls each. Put each pile in the chipping area, not on the green, between 5 and 20 yards from the hole.

Mark 9 stop zones on the green using tees, string, or buckets, spaced across the green.

Hit 4 flop shots at each stop zone, trying to stop each ball in the zone.

Start at any pile and pick a stop zone. Hit 4 balls from the pile to that zone.

Move to the next pile and new stop zone. Keep going until all 9 zones have 4 shots each (36 shots total).

Count each ball that stops inside the right stop zone.

Enter the number of successful shots in the app, out of 36 attempts.

Make 4 piles of 9 balls: 2 piles uphill in deep rough, 2 piles downhill in deep rough, all 5 to 20 yards from the hole.

Mark 3 landing zones on the green in a line, each 6 feet apart: Zone A (closest), Zone B (middle), Zone C (farthest).

Hit 36 flop shots: 3 groups of 12 shots.

For first 12 shots, hit from uphill piles aiming for Zone A, switching between the two piles after each shot.

For next 12 shots, hit from uphill piles aiming for Zone B, switch piles after each shot.

For last 12 shots, hit from downhill piles aiming for Zone C, switch piles after each shot.

A shot counts if it lands and stops in the target zone.

Use same ball position every time. Only change aim for zone and slope.

Count how many landed in the target zone out of 36 and enter score in the app.
