You only have to start each mission, you don't need to complete them.
Hit the 3 targets at the top of the table.
Once you hit all 3 targets the spinning disc will rise from the table. There are 2 holes to hit, hit the right hole and you start a mission. Once the mission starts, try to complete it. Finish all 6 missions, completed or not and then hit it once more into the right hole in the spinning disc and start the wizard mode, which is just for scoring points. Once it's complete you have your achievement.
The video is from the 360 version, but they are the same here too
