How to Win Sega UFO Catcher Minigame
You have to hold the button till it reaches the position you want.
So the first time you press A it is going to move right till you release it. Then the camera will shift and you can move it back. Again hold A till it is roughly in the position you want. When you release the claw will lower.
Hope this helps :)
You can talk to the store guy to reset the given toys.
