In the game, children learn the first simple subtraction problems. The objective is to find matching cards, and the game is easy to understand and play for everyone. For example, the card with “3-1” needs to be matched with the card showing “2.” When a card is flipped, the equation or result is read aloud. Memory games are an excellent learning tool because they combine play and learning in an engaging way. The game strengthens children’s concentration and memory while also training their ability to recognize patterns and make connections. This happens in a fun and natural way, where repetition doesn’t feel boring. The interactive approach makes it easier to maintain children’s attention and helps make learning a positive and motivating experience. The game is part of a series of educational games for children aged 3–10. These games make learning the alphabet, numbers, words, and much more fun.
