All the ice will be melted in >200 days, without ever being able to form a square. OH, NO! NOT AGAIN! And the fact that I specifically mentioned "ON ALL FOUR SIDES" (this fooled me too) didn't help you? All the ice will be melted in 103 days! The reason? It erodes half a foot from left and half a foot from right, so (in all) the dimensions decrease dayly by one. Second idea: how the heck did you look for a solution? My idea was that there are five of them and all are somewhat rectangle-shaped, so they better become a "little" smaller. Next step: start to add their areas in order to give a perfect "square" (is this notion of math in English too?). Conclusion: after 97 days, the blocks become: #1 - 5 x 3 (area: 15) #2 - 4 x 3 (area: 12) #3 - 6 x 2 (area: 12) #4 - 4 x 1 (area: 04) #5 - 6 x 1 (area: 06) Total area: 49 = 7 x 7. So now it's simple enough because the five tiny leftover DO FIT in a 7 x 7 square: 1111133 1111133 1111133 4222233 4222233 4222233 4555555 I told you guys I was leaving this for Chip. It's not quite that simple (or is it?) >Einstein Quiz. I did it in 22 mins. But what helped me were 25 tiny bits of paper, each with the nationality/color-of-house/beverage/pet/cigar-brand on it AND one hypothesis: >4 - The green house is on the left of the white house means that the green house is DIRECTLY "on the left" of the white house. If 4 would mean GENERALLY "on the left" of the white house, we could have this arrangement: -bird- --cat- -dog- -horse --fish- PallM. Prince Blend BlueM. Dunhill -green -blue- white --red- -yellow -Norw- -Germ- -Swe- -Brit- --Dane- coffee -water -milk -beer- --tea-- (8 more minutes) or -bird- **** -dog- ***** -horse <- those ''s can be replaced by either 'cat' or 'fish'. PallM. Prince Blend Dunhill BlueM. -green -blue- white -yellow --red- -Norw- -Germ- -Swe- --Dane- -Brit- coffee -water -milk --tea-- -beer- (7 or less) or -bird- *** horse ***** --dog- <- those '*'s can be replaced by either 'cat' or 'fish'. PallM. Prince Blend Dunhill BlueM. -green -blue- -red- -yellow -white -Norw- -Germ- -Brit --Dane- --Swe- coffee -water -milk --tea-- -beer- (9 or less) or -fish- --cat- --dog-- -horse -bird- -Blend Prince Dunhill BlueM. PallM. -green -blue- -yellow --red- -white -Norw- -Germ- --Swe-- -Brit- -Dane- coffee -water --milk- -beer- --tea- (4 more minutes - that makes an hour 'wasted' on this problem!) >Who has fish for pets? "ascii(52)ascii(116)ascii(104)", "ascii(80)ascii(114)ascii(105)ascii(110)ascii(99)ascii(101)", "ascii(103)...", "ascii(71)..." or "ascii(99)..."? (solved in the first 22 minutes) I made that in an editor with the possibility to view the current character's code, I DO NOT have such a long memory as to remember all the codes.
