Its a addictive game. Play the numeric trick against Alexa! In this game, your task is to choose at least 3 numbers among 1 to 9 which add up to 15. You and me will take alternative turns in the game and tell a number one at a time. You should not repeat the number which was already told by either me or you. You may pick 3 or more numbers, but when the sum of any three numbers give 15, you win the game.
