Tips to get a high score

Play the "relaxed mode", which is unending as long as you don't miss a buoy.
Use coins when there are a large number of face-down cards on the field.
Although it's possible to make runs either up or down, you can maximize your point potential by picking one direction. That way, you won't end up with unplayable cards leftover at the end of the deck.
At the beginning of the game, when your run is still very short, it's better to hand-splash the water rather than use a coin, so that you can build up a coin reserve.
Since the score for each card is proportional to the length of your run, the key to this game is making a run as long as possible.
If two cards are overlapping, and you're not sure you can click the card you want, don't risk it. If you wait, they may drift apart. Alternately, there may be another card on the pool which you can play. If all else fails, wait until the cards loop around the pool, and they probably won't be overlapping anymore.
