Memory Penguins Remember

In the game there is a field with inverted cards, on the reverse side of which various Penguins are depicted. Clicking on the cards, they open one at a time, and then turn over again.

Remembering what kind of Penguins there is depicted, you need to find the same Penguins among the other cards. After that cards with the same Penguins remain open and then disappear from the field.

The game has 3 levels of difficulty: easy (field 2x3), medium (field 3x4) and complex (field 4x5). And also there is a level where you need to find a couple of all the Penguins for a while.
