Number Games
You need to know when to stay silent and when to act. If you think you've figured that out, try Number Game. Number Game is a reflex test game based on sound. The game will play sounds that may correspond to the number of digits in the displayed sum, and when that happens, you must press the enter key. When the sound played doesn't match the number of digits, you have absolutely nothing to do except make sure you keep up with the pace of the game because time is not your friend here, so you must find the perfect balance between speed and accuracy to achieve the highest score.
