The point of Archery is to try and shoot all of the targets given on the "bulls-eye", then move onto the next level. After the player successfully completes all of the levels, he or she must fight the boss. To defeat the boss he/she must shoot the dragon enough times to make it turn all black. After the Dragon is defeated, the player is given his or her time and unlocks AR Shot and Mii Pics.
When fighting the boss, the dragon will attack meaning you can't shoot arrows at it. So quickly turn your AR Card around and the dragon will be facing the other way. Then, shoot as many arrows as you can before it turns around.
IN NEED OF IMAGES. Will post later.
