Manhattan - Variants

The following rules are included in the Mayfair edition.

Monster
This variant requires that a player supply an extra figure to represent a monster that is destroying Manhattan.  Place this piece randomly on the board before the game begins.  Whenever a player plays a card, move the monster one square in the direction indicated on the card.  If there is a building in that block, it is destroyed and those pieces are removed from the game.  If the monster tries to leave a neighbourhood, move him to the adjacent neighbourhood (as if all 6 were lined up in a 3x2 rectangle).  Squares with a monster on them cannot be built on.  If the monster leaves the board he comes back on the other side!

Baby Monster
This uses all the same rules as the monster variant , but instead of destroying entire buildings,the baby monster only removes the top piece.  When a player plays a middle square card, the baby monster removes another piece of the same building.

Slow Growth
In the first round, only three neighbourhoods are available for building.  No pieces may be played in the other three neighbourhoods.  In each additional round, one more neighbourhood becomes available for building.

Anti-trust Laws
No player may place a piece on top of one of their own buildings.
