The challenge of the game is how to combine the basic colours red, blue and yellow to create new colours. The winner is the first player to produce his favorite colours. Things get tricky when players compete for the basic colours and colour plans are intercepted. Experienced players develop the talent to detect their opponents colour plans and include them in their own colour strategy. The gameplay is as follows. Every player gets a few hidden goal cards with colors. Than the active player draws one colour disc from the bag. Using his colour discs he can move the current marker in the direction of the chosen discs on the rondel. Once the player reaches his secret goal he can reveal one of his cards.
