Use Alexa for playing Hide and Seek by equipping an Echo Dot with a battery pack, e.g. a mobile powerbank, so it can be hidden somewhere.
When you want to play the game you say: "Alexa tell Hide Seek to start game" - Alexa then explains the rules of the game, which are very simple.
One person e.g. the adult, takes the Echo Dot and hides it somewhere for the kid(s) to find. Once Alexa is hidden say: "Alexa tell hide seek ready".
From this point a timer starts, and it is up to the kid(s) to find the Alexa, if they need a clue, they can say "Alexa tell hide seek where are you" and Alexa will shout something as an auditory clue.
Finally, when Alexa is found, you tell her: "Alexa tell hide seek found you", and she replies with how many seconds it took to find her.
