Pineapple Smoothies
The first thing you need to do when you start the game is plant a crop of pineapples so they can be harvested at a later time and then taken to the Tiki Bar were they can be turned into pineapple smoothies.
Trade-Off
There will be times you will need to use an item to get others. Take advantage of these trade-offs such as giving the dolphin one pineapple so it yields you two fish.
Snorkel
Early in the game when you are working the Coral Reef send customers snorkeling as often as you can to get crabs. It will cost you one pineapple smoothie a customer for a 15 minute dive and you will earn XP and special bonuses from them. The Coral Reef is the only place you can get crabs which will come in useful when completing quests.

Achievements
Keep an eye on the Achievements bar as you can earn gems as rewards for completing tasks you were going to do anyway. This is a good way to stockpile gems.

Free Gem
It's always worth doing when it is offered the quest that simply requires you to watch a video in exchange for a gem.
Trade Boat
Use the trade boat to sell your excess supplies for a profit and also when you need to buy items you are short on.
Beach Clubs
Don't forget about the feature that allows you and your friends to create social Beach Clubs and live chat with each other in real-time.
