Carnival Island

See Tree House Way Master for general info. The only difference is the games in question. In this case the game is Coin Toss. When in-game press to open up the challenge-menu.

Specific game tips:
Coin Toss: For legendary you'll have to get a lot of coins on the 80. Filling up the 50 and making some of them fall down on the 80 might work. Moving one coin to another point circle will give you more points.

Nom Nom: Many of the challenges will require you to make the monster spit out coins. This can be done by hitting the flashing space (10/50/80/20/30) and in the following throw tossing a coin into the mouth of the monster.

Gold Digger: This challenge is a bit luck based - some challenges depends on you finding the treasure in X number of throws. Since there is no timer in this game just take your time aiming when going for the legendary challenge.

Teacup Towers: Doing the legendary challenge will complete the rest of the challenges. Start with the cups in the back but do not raise them to the 4th level if you haven't found the arrow!

Roundabout: When going for points make sure that you'll get the bonus in the upper tier. When getting the bonus and 50 in one throw you'll have to learn the tempo of how fast the lower tier spins AND learn how fast the coin falls from the upper tier. If you have problems with hitting the 50 multiple times just aim at that one without going for the upper tier.
