A file containing latest products and their prices from various online retailers is uploaded to S3. When the skill is launched, it reads this file from S3 to formulate various questions. Since a new file is loaded to S3 often, the product list gets refreshed frequently and so players will never get bored if they regularly play the game .
The question read to the participants will be the product description and 4 possible prices. The participant has to press the button and guess the right price.
Invoke the skill with the phrase "alexa open pick the price".
When the skill asks you the number of players, say for example "two players" not just "two".
