There's two reviews on IFDB that comment on the puzzle involving the cigarettes. I've played the game through a few times and examined all 80 packs of cigarettes and I'll be buggered if I can even find the puzzle. Is there really a puzzle or were those reviews just having a go at you?
I've read the advertisements, found the $2.00 in quarters, brute forced the purchase of Claymounts, found and lit the lighter and attempted to light the stove and gas main with the lit lighter (expecting to get blown up), all to no avail. So, where on Earth is this puzzle that the IFDB reviewers are raving over?
