Each player in Tubyrinth has a set of pipes — "tubes", one might say — and each round in the game each player has a playing board that shows an entry point and an exit point; the game includes 42 double-sided boards, each with a different design. Players race to use 5-7 of their pipes to create a path from entry to exit on their board. The first player to create such a path scores 5-7 points, while all the other players score 0-2 points (7 minus however many pieces the winning player used). After someone wins, each player takes a new board, and whoever first scores 25 points wins!
