Your Granny's position as the town's top handicrafter is threatened by upstart contenders from a new retirement community. Your task is to try to help her, while distracting and sabotaging her competitors – but if you don't keep your loyalty hidden, the other players will definitely stitch you up!
At the beginning of Granny Wars: A Game of Tit for Tat, you receive a secret loyalty card matching one of the Granny cards on the table, and you are dealt ten cards which range from -5 to +5 points. The deck also includes Gold cards, which grant a special Granny power (like "Nana Nap") in addition to points. Players take turns adding cards to the Grannies, and the "Tit for Tat" mechanism allows a player to "bounce" an equal and opposite card from one pile to another, e.g., playing a +3 on a -3 lets you move the -3 to another pile of your choice.
After everyone has exhausted his cards, players reveal which Granny they supported and sum the points in her pile of cards.
