Mammalath

Mammalath is an animal-themed board game inspired by the idea of having a winning condition and a losing condition that’s a subset of the winning condition, as seen in Yavalath (by Cameron Browne’s Ludi) and Manalath (by Dieter Stein and Néstor Romeral Andrés). The goal is to capture three squares in a horizontal, vertical, or diagonal row which don’t contain animals. However, if you make three in a row and at least one animal is in those cells, you lose! (Think of the members of an animal activist group getting angry at you for capturing the animals.) To win, you must strategically free the animals while going for three in a row. —description from the designer
