Tap two bubbles that add up to the target number. Chain combos to multiply your score!
Find pairs of floating bubbles that add up to the target number shown at the top of the screen. Tap two bubbles whose values sum to the target — they pop and you score points. Clear as many pairs as possible before time runs out!
Tap any bubble to select it (it glows). Then tap a second bubble. If both values add up to the target, they pop and you earn 100 points. If they don't match, both shake, you lose your selection, and 5 seconds are deducted from the timer.
Pop 3 correct pairs in a row without a mistake to activate 2× Combo mode. While combo is active, every correct pair scores 200 points instead of 100. One wrong answer breaks the combo streak. Chain combos to explode your score!
Every 4 correct pairs, the target number changes. New bubbles spawn with values that guarantee at least one valid pair. If the board ever has no valid pairs, the game silently adjusts bubble values so you're never stuck.
If you clear all bubbles on the board before time runs out, you earn a time bonus of 5 points per second remaining. Fast clearers are heavily rewarded.
Seven levels from Beginner (small targets, more time, fewer bubbles) to Cyborg ☠ (large targets, tight timer, packed board). Each level adjusts the target range, bubble count, and time limit.
