Monster 10 is a very addictive game. You need to sum up two or more numbers from the range of 1 to 9 and make it equal to 10 to kill Monster 10. All different Monster Numbers will fly from the Spaceship faster and faster until you can’t take it anymore. No one can break the record of 0.6 second attacking speed which is almost the limit of your brain’s calculation and reaction time. The concept of this game has been around for decades even without game console years. Million students are playing in their calculators. It is good to train the memory. Now it revives in your device. Enjoy the game and let me know if you break the record of 0.6s.
