When installing the application, we have a choice of three large groups: the animal group, the vegetable group, and the fruit group. When clicking on one group, I choose between the approach that I want, easy, medium, or difficult, then I click on the follow-up, and a screen opens for us that includes Arabic letters with the words at the top and what is meant Search for it...I am looking for the sequence of letters to form a word from the words that appear at the top. The sequence of letters is horizontal in both directions or vertical in both directions, or the sequence of letters is diagonal in the four directions. I click on the first letter of the word I am looking for and then drag in the direction of the letters that make up the word until I reach the correct answer....I try to form all the words as soon as possible...then I click on play again or move to another axis ....
