I will list strategies for the harder holes, but most of them you should pass with ease. Here are a few tips.
*IMPORTANT* - The computer typically finishes the game with a +2 or +3 (this is their best case scenario). So if you need to sacrifice a par, bogey, etc. to keep your conditions in check you should do so.
Win with over XXXX points or Win with a total score of -X
If you struggle with these challenges, come back when you have better gear and the expert characters. With their high stat of power, you should be able to reach par5's for eagles and even some par4's in one shot.
Have a fairway keep XX% and win.
Fairway keep is driving the ball off the tee and landing in the fairway. The best tip I can give you is DO NOT USE YOUR DRIVER. Your driver has the worst accuracy and all it takes is one miss to ruin this challenge. If you need to, use a 7-8 iron and drive the ball 150 yards off the tee into a nice big fairway area. It might ruin your chances for a birdie, but to beat the computer they are usually not necessary.
Fairway Hit % does not calculate par3's. Use this to your advantage
Avoid Rough/Bunker/Waterhazard/Out of Bounds
If you need to avoid the bunker, water, and out of bounds, you should easily be able to do these. Make sure you are careful with your shots and you should be able to complete these on the first try.
Avoiding the rough is the worst condition since the rough....well is everywhere. You will need to be very careful with your ball placement and sometimes you will be forced to hit the ball much shorter than you can so you reach a safe area. I would concentrate on scoring high the first few holes so you can be really safe near the end.
Have a Green in Regulation of XX%
Typically this will be the hardest challenges in the game. Green in Regulation means reaching the green and being able to attempt a birdie or better putt. So that means reaching the green in 1 shot on a par 3, 2 shots on a par 4, and 3 shots on par 5. If you need a 100%, then you need to play an excellent round of golf to achieve it.
The best tip I can give you is do not go for the pin but rather the middle of the green. Sometimes the pin is placed near the fringe of the green and this can be very dangerous as the ball can easily be mis-hit or roll off the green.
Land within Xm of the Pin and Win
These conditions require you to be Green in Regulation so you cannot sneak up to the green and have an easy chip....most of the time . If you are having trouble with the 1m and 2m requirements, I would suggest taking advantage of the par 5 holes. What you can do is power up your first shot and rather than shooting for the green in the 2nd shot, get as close to the green as you can. If you can do this correctly, you will leave yourself with a 20-30m chip-shot to get this challenge.
A chip-in will count for the trophy as well, but it will need to be an eagle or double eagle.
Have a Perfect Impact XX%
This is another condition where I cannot really help with. Pick whichever style of shot meter is the most comfortable for you and concentrate on that accuracy. 30% should not cause to many problems but 50% will require skill.
Win with all Spin Shots or no Spin Shots
One of the easier conditions as long as you keep your hand on/away from the directional pad. If it requires all spin shots, always hold the directional button down (or attempt a different spin shot). If it is no spin shots, keep your hands off the directional buttons at all times. I find the no spin shots slightly tricky since it is forcing me to do something I do not want to do
