Each player is the only one who knows which color they want to eliminate from the game board. Players take turns removing groups of counters of the same color. Just press on the counters then watch as they slide out. The counters above them slide down to take their place. You have to be crafty to completely remove all the counters of your color. if your opponent figures it out, they might block you. This includes a game board with 100 color pops.
