Passing through levels is your measure of success in Candy Crush Jelly Saga. Your skills as a player are recognized as you'll move up through the map as you succeed in each challenge.
The First Attempt pin is a marker to symbolize the most excellent of gameplay, as you'll receive one for each level if you pass the level on the first attempt, i.e. without losing a life.
To remain fair to all our players, the First Attempt pin can be won without the use of gold bar purchases, such as extra moves. You can use boosters of course, but your skill and talent as a player is the strongest path to success. For this reason, the appearance of the pin on the game map is the reward here and there's no separate prize for this achievement.
Play well and strategically and you can string the pins wins together. Sit back and admire the path of glittering success on your map!
