Can You Draw a Perfect Circle

When I finished my book, How Round Is Your Circle?: Where Engineering and Mathematics Meet, I wanted to check the reviews on Goodreads to see what other people think about that book. In one of the reviews, I met with Neal Agarwal’s beautiful game, “Can You Draw a Perfect Circle.”

Neal Agarwal’s “Can You Draw a Perfect Circle” project is a challenge in itself! With the website, Neal Agarwal offers an innovative way of testing your ability to draw a perfect circle under pressure. You must click and drag your mouse around the white dot in the center of the page. Or you can use your touchscreen phone to draw a perfect circle!

This perfect circle drawing game tracks the speed of your movements and how close you are to forming an exact circle. After completion, it gives you a numeric score to show how close you were to make it perfect – any percentage above 90 indicates excellent control, and 100 percent perfection means spectacular results!

By the way, there are some things you should know. First, use your phone instead of your computer because it is extremely easier on your touchscreen phone! Second, keep in mind that you are going to draw tons of perfect circles! If you can draw one, you will be really happy! And don’t bother yourself by checking Youtube! I did, and I couldn’t find any perfect score!

Can You Draw a Perfect Circle is also a great tool to use when you give your students free time! It is really my student’s favorite game these days! Every time I say, “It is can you draw a perfect circle time,” they immediately type “drawperfectcircle, draw, draw a perfect sircle” on Google! Yes, many of them “sircle” instead of “circle.”

I think today is a good time to try to make a perfect circle with your friends! Don’t forget to take a screenshot every time you break your record! It is a good thing to keep your data!
