In Count Speed 3D, you can boost your speed using math. Navigate your vehicle through blue and red portals to alter your speed and avoid hazards and lethal enemies as you make your way along a track constructed entirely out of water. Avoid the checkpoints and drive to the back of the queue to increase your score. 

Use high-end, cutting-edge vehicles and strategic decision-making to set new high scores. On this course, your rivals are not other vehicles so much as they are speed bumps, cones, and enormous cleavers. As the automobile hurtles toward the finish line, all you have to do is guide it. Passing through portals will alter your vehicle's velocity, but you have no say over its speed. Your movement rate increases through blue portals and decreases through red ones. You'll need to do some rapid math as your car approaches the next portal so you can pick the best decision to bring you to the end zone as soon as possible. You may need to choose between two gateways of the same hue. Make the most of your mathematical abilities to achieve your goal. New vehicles can be purchased and unlocked from the store, so be sure to check it out.
