Memory Game App Using MIT App Inventor

The Memory Game App is a simple and interactive mobile application developed using MIT App Inventor. It helps improve memory, focus, and concentration skills in a fun and engaging way.

In this game:

• A set of cards (buttons) hides symbols, numbers, or images.

• The player taps two cards at a time.

• If both cards match → they remain visible.

• If they don’t match → they flip back after a short delay.

• The game continues until all pairs are matched.

This project is ideal for beginners learning lists, variables, conditions, and event handling.

Game Objective

• Find all matching pairs.

• Complete the game in minimum attempts.

• Improve memory and observation skills.

 Components Used

 1. Lists (Images / Symbols List)

A List stores symbols or image names.

Example:

["🍎","🍎","⭐","⭐","🎈","🎈","🌸","🌸"]

• Items are arranged in pairs.

• Randomly assigned to buttons at the start.

 2. Global Variables

Used to control game logic:

• FirstSelected

• SecondSelected

• FirstButton

• SecondButton

• MatchCount

• AttemptCount

---

3. Button.Click Blocks

When a button (card) is clicked:

• Reveal its hidden image.

• Store it as first or second selection.

• Check for match when two cards are selected.

---

 4. set Button.Image / Text

Displays the symbol or image when a card is clicked.
