In this game you see combinations of cells and names. Is the combination correct? Then swipe right. If not, swipe left.

You can also use the buttons at the bottom of the page. On the computer, left and right arrows also work.

Each level contains different types of cells. The higher you go, the more difficult and rare the cells become. You have a total of 20 seconds to assess as many cells as possible. For each correct answer, you get a few seconds more.
