This achievement will automatically pop apon finished the final level along with:
You want to make sure you do all levels in one sitting as game progress will be lost as soon as you shut the game down.
For the levels it's all pretty simple, some luck based levels but noting too challenging in my opinion. I only ever got stuck on level 27 which in my opinion is the most frustrating level. I would recommend these Power-ups for this level:
Shield Pass: You'll need this one to pass through the red force field at the end of the level.
Steering: You'll need this to curve round and control the ball around the course.
Jumper 2: I'd recommend getting this to the 2nd or max upgrade as this one will help you jump over the gaps on the course. If you go fast enough sometimes the ball will bounce over the gaps anyway but then your more likely to over shoot it and fall off the course.
I think the par for the course is 4 but you can do it in 5 shots and still pass.
If those skills didn't help out there are also:
Turbo: This will increase the speed the ball travels.
Hole magnet: This power up gives a better chance of getting the ball sucked in the hole.
Mulligan: Lets you retake a shot.
Always use the power ups that you find most useful for the level your playing.
