In I Go!, players draw and discard iteratively, attempting to improve the quality of their hands. You can improve your hand by forming a run (using 1 or 2 colors), matching the top card of the 'display' stack, or simply keeping low values cards. After your turn, you can declare "I Go!" to claim that you have the best hand (fewest penalty points). Other players can then play off of your run, and the best hand scores a point. First to 4 points wins.
