Barboskin's game Covering up traces

The puppies in this apartment have done something again, and therefore, covering their tracks, the Barboskins distract your attention with all sorts of puzzles. On the other hand, the fun they offer is very useful for the development of attention and memory. The point is this. Pictures are displayed for a short time. You need to remember their location and open the same ones in pairs. There are many attempts, as you can play online for free.
