To control your character you just need to move your fingers on the display of your smartphone imitating swimming motions or rolling bicycle pedals. The most noticeable thing is a funny 'mechanics' of the cartoonish participants. You can play with as many friends as you wish, the key is to make fun! To enter the game, you need to download mobile Chrome browser first. A good way of advertising your browser, by unintrusive reminding of its fastness.
