It's not easy making a cool otter den. You'll want to influence the best otters to hang out in yours. And often you’ll get to decide which otter goes where. Do you want this otter? Or an otter won? An Otter Won is a spiritual sequel to Why I Otter, taking everything up a notch (including the ridiculous otters).
In An Otter Won you have personal conditions in the cards you've taken into your den that play off public otter cards in the river. It uses a neutral setup card per trick that may help determine if the high or the low card wins the round. The winner assigns those 3 cards (neutral, yours, and opponents) and which goes to which location (Opponent den, your den and the river).
