THE NIGHT CAGE is intended to be difficult to win, but you can make simple tweaks to adjust the difficulty. To make things easier, add a Key tile or two to the tile count. To increase the difficulty, remove a single Key or Gate tile from the tile count (or both, if you are a glutton for punishment). Or swap two T Passages for Crumbling versions.
EERIE SILENCE VARIANT: Limit communication between players, so that Prisoners cannot speak to each other unless they are connected by a passageway
