Signal Board Game

In Signal, players take on the role of Experts seeking to understand the Alien player, who in turn is seeking to be understood. The Experts will create and transmit "signals" to the Alien, who has certain rules for how to respond that must be deduced by the Experts. Once the Experts understand these rules, they can ensure that they come to agreement with the Alien, succeeding co-operatively. After succeeding at the first round, Experts then reset and continue with the same Alien, except new rules are in play on top of the previous ones, showing a deeper and deeper familiarity with the Alien player. After three rounds of successful agreements, all players win co-operatively and receive a score based on leftover guesses and unused abilities.
