PDF, Mobi	Page 13 Bottom half	The problem "Opening the Alien Lock" is insufficiently constrained. It is never stated that you can only slide one Kratzz at a time. Therefore, my initial solution was to hold down the Alarm suppressor and then slide all the Kratzz over to the left side (holding the suppressor down when sliding the Kratzz in). Also, zero is an even number too, so the next rule has to be: "...sensors that light up if the number of Quinicrys in the column above is positive and even." or better "is 2." (since numbers > 2 are impossible anyway). Otherwise the problem is unsolvable.	Tim Pietzcker	Aug 24, 2012
