In Block Ness, players take turns choosing a monster segment from their reserve and using it to increase the length of their creature on the Loch game board. Each new segment must be placed next to your monster's head or tail — with the head or tail piece then moving to the far side of the newly-placed piece — and you can cross the path of other monsters on the board only if you can go above them.
Once all players are blocked or everyone has placed all of their segments (with the size of the game board changing depending on the number of players), whoever has the fewest segments remaining in their reserve wins. In case of a tie, the tied player whose monster head has the highest elevation wins.
