About

Memo Forms

Features

Read full description

Visual memory game with simple geometric figures and icons. The board consists of several fields (depending on the board chosen) and each one of them hides a form. The idea is to open pairs of fields that are the same. When the two open fields are the same, they stay open and change to green. If they are not the same, the cells change to red and close again. You have to get all the fields of the board left open in the shortest time possible. The app will help you develop your mind by improving and training your visual memory. The game is perfect for everyone, both for the youngest who are developing their memory, and for adults who need to stay mentally fit.
