An exciting and fascinating family game named after TAYU, the legendary Chinese hero who saved his country from flooding by creating a system of waterways.
As far as you can, use the tiles to lay water channels from one end of the board to the other. At the same time try to block your opponent(s) by diverting their channels in other directions. The player who at the end of the game has the most channel connections at his or her two ends of the board is the winner.
