This game challenges players to help identical bacteria twins locate each other. It functions as a short-term memory test, where players need to identify matches between bacteria pairs. The faces of non-matching pairs flash briefly before closing again.

You can open any 2 bacteria at a time, and it's your responsibility to connect the identical twins again. If you find 2 identical bacteria twins, they will remain open and happy. Once you match all the 12 pairs, you are done. However, you need to complete the task before the time runs out to score points.
You start with 3500 points, and the faster you match the bacteria twins, the more points you score. If you score above 2000 points, it means you have excellent memory powers. Basically, this game is designed to test your short-term memory.
When you click on 2 bacteria that are not identical, their faces flash for less than a second before they close up. So, you need to remember where all the faces are to reunite the identical twins quickly. By playing Bacteria Pairs, you can sharpen your short-term memory powers and remember instant information more effectively.
