Amend the list in the rule “Movement” to read:
- Scamper: move any number of Cells in a cardinal direction, so long as this move does not pass through any walls or any cell which contains a Tranquilliser.
- Crawl: move from A4 to G4 (or vice versa) or from D1 to D7 (or vice versa).
- Limp: move in to or out of a cell which contains a Tranquilliser and no other Rats, so long as this move does not pass through any walls.
Add a sub-rule, “Tranquillisers”, to the rule “Spawners”:
A Tranquilliser is a Spawner which inhibits Progress through the Cell it occupies, as defined by the rule “Movement”. A Tranquilliser may not occupy a Cell which contains another Tranquilliser or is adjacent to a Cell which contains a Tranquilliser. There are Tranquillisers in Cells [X1, X2, X3 and X4].
Add a sub-rule, “Random Selection of Cells”, to the rule “The Maze”:
An acceptable method to randomly select a Cell is to roll two separate DICE7, using the first to find the column, with 1 signifying A and 7 signifying G, and using the second to find the row.
Randomly select four Cells which can legally contain a Tranquilliser and add a Tranquilliser to those Cells, amending the list of Cells in the rule Tranquillisers and the table underneath the picture of The Maze to reflect this.
