Hello!

You mean the memory test, right? After playing 15 monster card, go to the far right of shooter park and there is a game area. Go in and talk to the NPC inside. Then he asks you what game you want to play, and you can do a memory test. Give him 15 monster card and help you do it. Open other windows of the backpack and see if there are any props called memory test. Double-click to start playing, but you can't play until other players join. At first, I will flip the cards once, remember which two of those cards are the same, and then flip the cards again, and the one that turns over more will win.

Answer finished, hope to adopt!
