Alexa Skills can give users access to accounts they've already set-up, such as the Alexa Skill for SiriusXM radio, ESPN, or even their car insurance if they have Alliance Insurance. With Alexa connected to these accounts, people can pull up details and content through their Alexa-enabled device. For example, the Alexa Skill for Major League Baseball lets Alexa users stay current with baseball stats and hear shows. Use the Alexa Skill for Fandango to not just find a movie but buy a ticket.
Warner Brothers created a choose-your-own-adventure game for Alexa called The Wayne Investigation, wherein you investigate the death of Bruce Wayne's parents, Thomas and Martha Wayne. Start the game by saying, "Alexa, open The Wayne Investigation" and follow the prompts. Each choice you make affects the outcome of the story. This is one of the best examples of a game style that suits Alexa perfectly.
How does Alexa work? Once you buy an Amazon Alexa device — Amazon Tap or an Echo Dot — the device connects through WiFi or Bluetooth to the internet and then to other devices. With the most common devices, the Amazon Echo and Echo Dot, people merely say "Alexa," which wakes up the device, and then ask for what they want. Alexa Skills radically expands the bots repertoire, allowing users to perform more actions with voice-activated control through Alexa.
