Do you spell it by ordinary people or by the letters at the back?
If you have time, interest and mood, of course, it is a fight, but it is difficult and time-consuming. At first, I wanted to play head-to-head, but I was too tired, so I gave up on the same day, so I sorted out all the English letters on the back, spelled them in piles, and then put more than 20 puzzles together to form the final pattern. Personally, I think it is more practical.
