The correct answer should be "Tafadhali cheza." Right now on mobile, the correct answer is just "Tafadhali" and "cheza" is not available from the word bank at all.

tafadhali is please, isn't it? Where is the play part in the answer?

I guess the word 'tafadhali' by itself can mean 'go ahead' like in Arabic. So put in the right context (e.g. two people sitting in front of a board game ) you would not necessarily have to say the whole term 'tafadhali cheza' - yet here in the exercise without context this is rather confusing since it could imply many other possibilities as well.

On web right now, both "Tafadhali cheza" (the only correct answer available) and "Tafadhali" (which just means "please") are required answers.

When using a command with the word "tafadhali", you must use the formal way of saying commands. rather than just "cheza", it should be "ucheze."
