ことりぱーち (Kotori Perch)

Perched together on a branch, a flock of small birds must keep their balance while working as a team to push away meddlesome intruder pigeons. Every shove can trigger a chain reaction along the branch, so the birds must coordinate carefully: drive off the unwanted visitors without sending their own friends tumbling down. Kotori Perch is a cooperative trick-taking game in which card play is directly linked to the movement of bird pieces on a branch. Players win tricks to slide their bird tokens left or right, using coordinated moves to push “intruder pigeons” off the branch. However, movement happens through a bumping or chain-push effect, so winning a trick can create danger as well as opportunity. Players must use visible/public cards to plan together, manage risk, and achieve the perfect push that removes enemies while keeping allied birds safe. The listing also notes high difficulty and event cards for replayability.
