In all types of matches, players can use graphical "ticklers" (or "emotes") to communicate thoughts or feelings, including love or hatred of the dice and/or other players. Similar devices, referred to as "Fooms", were previously available in the Hardwood series of Xbox Live Arcade games. These can be used as an alternative to voice chat (which is supported but not required) in order to, for example, encourage opponents to "sweeten a deal" or warn that they are too close to winning. The ticklers are used by AI players to indicate their "mood" in response to a player's actions; pleasing AIs will influence them to treat the player as an ally (though not to the point of jeopardizing their position), while angering them will serve to focus their negative attention. AI players will react to player-directed emotes towards them as well.
