To the rule “Special Movement”, add the following Special Moves:

- A Pawn can move their Piece (if they have only one) from its current cell to the immediately next cell above it on the same board (if it exists) by rounding their sanity to the nearest prime number. In case of a tie, the Pawn can choose whether to round up or down.
- A Pawn can move their Piece (if they have only one) from its current cell to the immediately next cell below it on the same board (if it exists) by rounding their sanity to the nearest triangular number. In case of a tie, the Pawn can choose whether to round up or down.
For the purposes of these special moves, negative numbers are considered prime and/or triangular if and only if their absolute value is respectively prime and/or triangular.
