If you have an eagle eye that misses nothing and sharp reflexes that respond pretty spontaneously, then this challenge is just right for you. Have a glimpse of the balloon colors that flash before you for a second or two and identify their positions quickly.
Observe the balloon arrangement that flashes for a second or two and memorize their positions. Once the cards are flipped, click pairs consecutively and make them disappear. Complete the game before the timer fades.
