CHALLENGE MODE ACHIEVEMENTS (2 for 20
The following 2 achievements can only be obtained in Challenge Mode.
Just Beginning - 10
Finish the first mission in Challenge mode.
Despite the somewhat misleading description, you just need to complete ANY challenge in Challenge Mode. There is no scoring in Challenge Mode. You either complete the challenge or you don't. The Level 1 "Longest Putt" challenge is quite easy. Just sink the putt to complete the challenge.
Relentless Effort - 10
Retry the same challenge 20 times.
This achievement only requires that you retry a single challenge 20 times. After failing a challenge, hit the option in the lower left to "Retry" it. The longest putt challenges are very quick to fail and you can easily get this achievement out of the way in about 5 minutes by just shanking the putt and retrying over and over.
MISCELLANEOUS ACHIEVEMENTS (11 for 85
The following 11 achievements can be obtained in more than one game mode (except tutorial one) and involve completing miscellaneous tasks.
New Trainer - 5
Finish training mode.
Training can be found from the Main Menu, in Help & Options>Tutorial. All you need to do is complete this short tutorial on the basic controls of the game.
Good Start - 5
Finish the first hole.
This can either be done in Career Mode or Instant Play. You just need to finish a hole (i.e. get the ball in the cup).
Nice Shot - 5
Perform your first perfect swing.
To get a perfect swing, you must exactly hit both the blue mark for power and the green mark for accuracy on the meter when swinging the club. You will most certainly get this when progressing through Career Mode after just a little practice. At the scoring screen at the end of each hole, you can see how many perfect swings you had.
Nice Chip-In - 5
Perform your first chip-in.
To get a chip-in, you must hit the ball into the cup from a position off the green (using a club other than the putter). This will come with playing the game. The easiest place to get this is England, where there is weak wind. Just try and get a perfect swing on a shot that was auto-aligned with the hole and it has a good chance of going in.
Special Skill - 5
Use your first special skill with on of the characters.
Each character has an unique special skill that can be used for an advantage throughout the match. The special skill is different for each character and it slowly charges up over time. When it is available, the picture of your character will be blinking red. Hit the blinking button to activate the skill. Sometimes the skill is only available at a certain time (i.e. during putting or when the ball is in flight) and thus can only be activated at certain times. From the character select screen, you can click on the special skill to find out more information about it (the button under your character's skills).
First Gift - 10
Unlock a new item.
The word "item" encompasses clothing, hairstyles, golf balls, and clubs. You can unlock items by completing events in Career Mode and challenges. You will get this after the first event or challenge you complete.
Great Result - 10
Score your first par.
See "Eagle Eye."
First Birdie - 10
Score your first birdie.
See "Eagle Eye."
Eagle Eye - 10
Score your first eagle.
These three achievements will most likely come by the time your reach Level 25. In case you lived under a rock, getting par means completing the hole in the same number of shots as the par number for the hole. A birdie is completing the hole in one less stroke than par, while an eagle is completing the hole in two less strokes than par.
If you are having trouble, try the Par 5 holes on the England Course. You should easily be able to make it onto the green in two shots. If you can just make that put, you will earn an eagle. Also, getting a hole-in-one on a Par 3 hole is also technically an eagle, though I am unsure if this will unlock the achievement, as "EAGLE" does not pop-up on the screen.
Hole-in-One - 10
Score your first hole-in-one.
The only holes that this is even possible are Par 3's or 4's. Play on England and do the "Closest to the Pin" challenge (first suggested by roce96). Use the default aim, adjust for the wind if necessary, and go for a perfect swing (perfect power and accuracy). This will give you the best chance of getting a hole-in-one.
Secret Code - 10
Unlock the Ninth Character.
This achievement is currently unobtainable. To unlock the secret character, you have to enter a code of sorts. Unfortunately, the developers forgot to port this option to the Windows Phone version. A patch was promised in early 2012 to fix this achievement, but is yet to arrive. I will update when/if more information becomes available.
