Math Speed Racing Prime Composite

Keep on racing by keeping your race car fueled up and avoiding other cars.  Fuel up by getting the gas can that has the required prime or composite number based on the letter beside your racecar (P or C).  Game over if you run out of fuel or run into another racer.  As you play longer the numbers get larger but that shouldn't be a problem for Math Speed Racer!

Your racecar will have a letter beside it indicating what type of number will have good fuel: "P" for prime and "C" for composite. To get fuel, run into the correct prime or composite numbered fuel tank based on the letter next to your racecar.  Hit the wrong tank and you'll lose fuel.  See how far you can go before you run out of fuel or crash!  Collecting coins add to your score.  Also, if you want to reset the high score just click on the High Score field on the menu to do so.
