Play game with Excel: Learning English vocabulary and grammar

I have made a game using Excel worksheet and VBA, this game is use for teaching English in Vietnamese primary school:

1. Description:
-There are 3 levels: 4 x 4 cells, 4 x 6 cells, and 6 x 6 cells. You can choose to play any level.
- Player can choose to play by 1 or 2 player(s).

2. How to play:
- Click one cell within the numbering range, then once another. After clicking,the word of that cell would appear
- If the two selected cells have the same word, they will change the color, and Player's score(s) will be increased
- If the two words are different, both cells would go back to numbers, and the current scores will be decreased
- If the cell has the word "bonus", the Player will have a bonus of 300 scores.
- If the cell has the word "puzzle", the Player will have to answer a grammar multiple choices question. If correct, the Player's scores will be increased, and vice versa.
- When all the cells change into words, you win.
- You can choose to continue with the current level, (old words or new words), or to play the next level, or to quit the game.
- You also can choose to maintain the scores, or delete it.
And you could change whether how many player(s) will continue.

3. If you want to add new question to the database, select "Enter new questions" option, then click Add.

4. If you want to add new words into database, select "Enter new words" option, then click Add
