Click on the smallest number when the circle is green and click on the largest number when the circle is red. Get points for correct hits and lose points for every wrong hit. Easy to understand but difficult to master.
There are two game modes in Pastel. Play the endless mode to beat your own high-score. Try out the quest mode to gauge your performance in a more restricted environment. Your speed will be your only limitation.
Pastel enables you to create your own custom game by manipulating and tweaking the variables that bring a sense of balance in the game. Play around with these values, let them lose and see where it all goes.
