Mr. Jack

A character is visible if it stands on a lit hex (adjacent to a lit gaslight) or is on a hex adjacent to another character; a character is invisible if it is on an unlit hex and not adjacent to any other character (page 2).

After the four characters are played each round Jack must declare whether he is visible or invisible; if he is visible all invisible characters are proved innocent, and if he is invisible all visible characters are proved innocent — the Witness card is set accordingly and those innocents are marked (page 3).

You may move through hexes occupied by other characters because tokens don’t block movement, but you may not end a move on a hex already occupied unless you are making an accusation (page 5).

Most character abilities are mandatory and must be used when the character is played; the exceptions noted as optional are Sir William Gull’s swap and Miss Stealthy’s ability to cross obstacles (page 5).

Only Jack may move a character out an unblocked exit, and this can only be attempted during a round that follows one in which Jack was declared invisible (so Jack cannot leave during the first round); if Jack escapes he immediately wins (pages 3, 6).
