Help keep your brain cells alive, whilst killing a little time. ThinkBubbles is available on iPad, iPhone and iPod touch.
Simply pop the bubbles in sequence for wave after wave of bubbly fun. Tho', as you can see here, bubbles can be tagged with letters, numbers, roman numerals or musical notes. Oh...and they might be frontwards, backwards or upside down...wards.
