The game is simple and features one touch controls. Hold the screen to swim up or do not touch the screen to swim down. Avoid the hungry sharks and whales or it is game over! If you can catch a magic seahorse then you will gain a speed boost that will make you invincible for a short period of time.
The longer you can survive the the higher your score will go. Your high score will save automatically so you can always come back to try and beat your own high score! Now start swimming in Seahorse Splash!
