Circularis app for iPhone and iPad

Introducing Bison Software’s second app, Circularis, the fun and interactive way to keep your brain quick and your math skills sharp. Using your cleverness, you must find a way to eliminate all of the circles and maximize your score using the four basic operations: addition, subtraction, division, and multiplication. If you’re feeling smart, you can try to beat your score in Rush Mode, the race against the clock to gain the highest score before the time runs out. Using Game Center, you can compete against your friends to see which one of you is the sharpest mathematician on the new and highly addictive app, Circularis, today!
