Can confirm this works - I once had a treasure hunt using our Amazon Alexa dots - all bought cheaply on sales, and one in each room. My son would start in the living room, ask Alexa a keyword phrase to start, then the dot will give him a new clue and a room to take the answer to. He’d go to the next room, say, “alexa, the answer is xyz”, and if he got it right (and to the right dot), the dot would recognise it and give the next clue.

About 10 clues later he got a reward - good fun that doesn’t take huge amounts of money, and many households have a fair few alexa things kicking about by now.
