Stop Proliferation

Observe the small virus floating towards the virus on the center screen, and eliminate the corresponding small virus by adding the number you input and the first number through the numeric keypad below.

This is a game that tests the user's calculation ability and reaction ability. At the beginning of the game, a small virus with numbers will appear on the screen, and eliminate the virus by adding the number input and the first number through the numeric keypad below. If the small virus touches the center virus and it is absorbed, the virus will grow larger, and the game will fail when the virus size exceeds the warning line. In "hard" mode, the number of small balls will increase from 2 to 4, to see if you can prevent the spread of the virus.
