For another variety of pin golf-style format, you could also try pin bowling.
Pick a target score (make sure it's easily divisible by 10).
On a player's ball 1, if they reach the target score, they get a STRIKE. Nice job.
If they don't reach the target score, they get 1-9 based on whichever 1/10 of target score they've passed.
On a player's ball 2, (if necessary) if they reach the target score, they get a SPARE.
If they don't reach the target score, they get 1-9 based on whichever 1/10 of target score they've passed, minus the bowling score from ball 1.
Typical bowling score format rules apply (STRIKE counts next two balls' scores in the STRIKE frame, SPARE counts next one ball in SPARE frame).
Example: on Frame 1 of Centigrade 37 with target score of 60,000, if Player 1 scores 53,000, they get an "8" and play their ball 2. On ball 2 they score over 60,000, so they get a SPARE for that frame.
On Frame 2 of Joker Poker with target score of 80,000, Player 1 scores over 80,000 on ball 1, they get a STRIKE.
Thus, their Frame 1 score is 20. They don't play their ball 2.
On Frame 3 of Cyclone with target score of 1,000,000, Player 1 scores 255,000 on ball 1, and has a final score of 525,000 after ball 2. They get scores of 2 and 3 on this frame, for a total of 5. Their Frame 2 score is 15 (10+2+3), their Frame 3 score is 5, and their total score after Frame 2 is 35, and total score after Frame 3 is 40.
have fun!
