Your task when passing the test is to find the numbers from 1 to 50 as quickly as possible. The current number is displayed in the upper right corner. On a low level of complexity, the numbers found are hidden in contrast to the average. When activating a high level of complexity, numbers fall out in a random order. The maximum time for passing the test is 30 minutes. To receive achievements and participation in the ratings of players, you need to enter the Play Games. You can also support the developer by disabling advertising (you may need to restart the game).
