Push the ball into the U by drawing lines and polygons... but be quick or you won't level up to the next physics challenge! You have less than 2 minutes to find the formula to get the ball into the U basket. HOW IT WORKS - Draw as many lines or polygons as needed. - Both the ball and the lines react to the law of gravity. - Beware not to trap the ball inside a group of lines. - All the physics problems have a limited time to be solved. - Time limits have been carefully calculated to be challenging taking into account each level's difficulty. - Time limits can range from 5 and 18 seconds to 2 minutes. - A countdown timer will feature the available time to complete each physics problem. - If you need more time to complete a physics problem, you can use the Timex2 button. A free educational game with 100 physics puzzles to clear, Physics Drop Countdown provides hours of fun.
