Trick'n Treat

From BoardGameGeek:

Trick'n Treat is a trick-taking game with cooperative and competitive modes! Venture out in costumes on Halloween and collect candies, but beware of the ghosts who can bring you all sorts of cute surprises. Players follow standard trick-taking rules without a trump suit, with one candy card being selected for scoring after each trick. Players can play ghost cards that always follow suit and trigger special effects. After resolution, ghost cards are added to the Trick-winner's hand. In Cooperative Mode, each player needs to collect 4 different candy cards. In Competitive Mode, players are divided into two teams; the team that collects all ghost cards loses the game, otherwise the team with the higher score wins. -description from the designer
