Guess ASL - Sign Language

I am learning sign language. I downloaded this as an extra tool. I get the concept that you are supposed to guess the sign based on what the sign looks like. Sign language has many signs that clearly represent the word but there are many that don’t at all. On this game you’re watching people make a sign and then trying to guess the word, and then tap letters from a small selection of scrambled letters to spell it. Just tap the letters to fill in the boxes and spell the word. I am not learning from this. I cannot figure out what the sign is without any other context except just watching them do it, and so many just don’t look like anything. So I spend more time just trying to find a reasonable word amongst the scrambled letters and hope for the best. Maybe others will get benefit from it but I’m not getting much.
