Word scramble is a great game to test your vocabulary! Simply say "Alexa, ask word scramble to play", it will give you a random sequence of alphabetical letters, then you will have 20 seconds to figure out which word these letters can form. For example, if you hear "a, l, p, e, p", after 20 seconds, you can answer "it's apple", or say "I don't know" to get the answer.
