Bubble TapTap Free is one of numerous free, ad-supported apps in which you pop virtual bubble wrap, in a game that tries to simulate the visceral thrill of mashing that time-honored packing material.
The interface is simple: 40 bubbles, arrayed realistically in staggered rows, which you tap to audibly pop. The bubbles regenerate after a few seconds, letting you go back and pop as many as you can while a one-minute timer ticks off the seconds. The game also gives you a bonus for popping bubbles in quick succession, briefly showing you the number of bubbles chained together as you keep popping. After the timer is up, the app gives you performance stats: number of total hits, good pops, and bad pops (i.e., popping already-popped bubbles), as well as overall speed and accuracy.
In a classy move, the game's ads don't overlap any of the bubbles, appearing just below the bottommost row. When you finish a game, you can publish your score via email, Facebook, or Twitter, and you can also check leaderboards through GameCenter. Given the game's competent execution and handful of extras, Bubble TapTap Free is an above-average entry in this genre.
