Match, swipe and shuffle bubbles to level up.
The standard rules of MahJong apply, match like tiles or in this case bubbles, if they are free. Free bubbles are not blocked on the left, right or covered by another bubble.
Points and bonus bubble rewards are earned for matching bubbles, slashing floating bonus bubbles, and maxing out the point multiplier. Keep an eye on the timer, points decrease the longer it takes you to find a match.
Up the point multiplier by making a series of consecutive matches without any mistakes.
