You will hear/see a repeating pattern of colors flashing and notes playing. Try to memorize it and achieve better scores! If you want to play competitive heres 3 ways: Casual: Just try to reach a higher Level. Every level, a new color is added to the sequence. Intermediate: Getting more competitive. Now instead of higher Level, you just try to get as many color points (correct clicks) as possible ensuring a more exact score. Competitive: As competitive as it gets. Score increases more, the faster you click the correct color. If you want a world record this is the way to go. Make sure your logged in. And locked in too... Sorry had to be done
