A Board Game of the Month Club promo for January 2017 was a new Cooperative Alternate Play Rules set for Cow, Tiger, Santa Claus.
While it's winter-ish here in New Jersey, we still have plenty of long car rides. And instead of everyone fighting, we're going to work together and try to find some tough items (unless you pull the Santa Claus card in the next two weeks, that is).
This new rules card lets players join together and look for items as a group. More eyes should mean more points, but every 15 minutes you need to remove a card from play. When you find an item, it is scored and can not be scored again. As a reward, you may take a card that was removed from play back, and restart your 15 minute timer.
We're hitting the road again in Cow, Tiger, Santa Claus with the Co-Op rules card. This was a planned stretch goal that didn't make it. Instead of competing to be the first to find all three items, you are working as a group to get as many as possible before the clock resets your items.
