I still love them! My sister and I worked out a system to win them a lot. Here's what we figured out:
-Pick your target before putting the coins in!
-Look for the plushies that are not packed in or buried under the other. Some machines are easier to win than others because they're not packed in.
-There are mirrors in the back of the machine to throw you off. Have a friend stand to the side of the machine to look from the other angle and tell you if the claw is lined up.
-Get the claw really close to the plushie and do it with technical finesse.
-Don't waste too much money if you don't get it at first
That's the gist of it. The ones with basketballs and other prizes are usually crappy and hard to win. I'm usually pretty good at the plush toy ones.
