Well there is still a list of unsolved mathematical problems called Hilbert's 23 challenges.  Most math develops form the need to correlate new equations to streamline comparisons or find new ways to predict observable behavior.  the former being how calculus of founded.\n\nhttp://en.wikipedia.org/wiki/Hilbert's_problems

try contacting the unsolved mysteries website...well if there is one and if you do find the outcome you might want to share,now I'm curios.

I've got one of those books. Yeah "weird puzzle" makes sense. If you think about it, the creatures who were the Wuzzles were all 2 different creatures muddled together kind of like a puzzley thing and a lot of them made no sense at all, like "Bumblelion", half lion, half bee. That is weird.

If I knew of the treasure, it would not be hidden.\n\nGeesh. This is like asking: when is the ten o'clock tour? And how many undiscovered caves are there?

From Western tradition, puzzles called Magic Squares.  These are often as large as 8 X 8 and might take days to solve.

Perhaps the answer to the original version of the puzzle was meagry or aggry (as in "aggry bead"). \nThere are over 100 obsolete words that end in "-gry" (see below), and these two were in use until fairly recently.\nThis is the (presumed) original version of the puzzle from 1975. The possible answers (if obsolete words, names, and hyphenated compounds of "angry" and "hungry" are allowed) are plentiful. Most of the 124 listed below were in the 1933 edition of the Oxford English Dictionary, and all have appeared in some major dictionary of English:\n\n\naffect-hungry fire-angry MacLoingry Seagry \naggry Gagry mad-angry self-angry \nAgry girl-hungry mad-hungry selfe-angry \nahungry gonagry magry sensation-hungry \nair-hungry gry malgry sex-angry \nanhungry haegry man-hungry sex-hungry \nBadagry half-angry managry Shchigry \nBallingry hangry mannagry shiggry \nbegry heart-angry Margry Shtchigry \nbewgry heart-hungry maugry sight-hungry \nboroughmongry higry pigry mawgry skugry \nbowgry hogry meagry Sygry \nbraggry hogrymogry meat-hungry Tangry \nBugry hongry menagry Tchangry \nChockpugry hound-hungry messagry Tchigry \nCogry houngry music-hungry tear-angry \ncony-gry huggrymuggry nangry th'angry \nconyngry hund-hungry overangry tike-hungry \ncottagry Hungry Bungry Pelegry Tingry \nCroftangry hwngry Pingry toggry \ndiamond-hungry iggry Podagry ulgry \ndog-hungry Jagry Pongry unangry \ndogge-hungry job-hungry pottingry vergry \nDshagry kaingry power-hungry Vigry \nDzagry land-hungry profit-hungry vngry \neard-hungry Langry puggry war-hungry \nEchanuggry leather-hungry pugry Wigry \nEgry ledderhungry red-angry wind-hungry \neuer-angry life-hungry rungry yeard-hungry \never-angry Lisnagry scavengry yird-hungry \nfenegry losengry Schtschigry Ymagry \n\nSince there is no longer a real answer to this, modern versions of the puzzle have turned from being puzzles to being riddles. There are perhaps as many as a dozen versions in circulation - each with a different answer!\n\nTake a look at \nhttp://www.fun-with-words.com/word_gry_angry_hungry.html

Main article: Mathematics of Sudoku\n\nThe general problem of solving Sudoku puzzles on n2 x n2 boards of n x n blocks is known to be NP-complete [8]. This gives some indication of why Sudoku is difficult to solve, although on boards of finite size the problem is finite and can be solved by a deterministic finite automaton that knows the entire game tree.\n\nSolving Sudoku puzzles (as well as any other NP-hard problem) can be expressed as a graph colouring problem. The aim of the puzzle in its standard form is to construct a proper 9-colouring of a particular graph, given a partial 9-colouring. The graph in question has 81 vertices, one vertex for each cell of the grid. The vertices can be labelled with the ordered pairs (x,&#92;, y), where x and y are integers between 1 and 9. In this case, two distinct vertices labelled by (x,&#92;, y) and (x',&#92;, y') are joined by an edge if and only if:\n\n    * x = x'&#92;, or,\n    * y = y'&#92;, or,\n    * &#92;lceil x/3 &#92;rceil = &#92;lceil x'/3 &#92;rceil and &#92;lceil y/3 &#92;rceil = &#92;lceil y'/3 &#92;rceil\n\nThe puzzle is then completed by assigning an integer between 1 and 9 to each vertex, in such a way that vertices that are joined by an edge do not have the same integer assigned to them.\n\nA valid Sudoku solution grid is also a Latin square. There are significantly fewer valid Sudoku solution grids than Latin squares because Sudoku imposes the additional regional constraint. Nonetheless, the number of valid Sudoku solution grids for the standard 9×9 grid was calculated by Bertram Felgenhauer in 2005 to be 6,670,903,752,021,072,936,960 [9] (sequence A107739 in OEIS). This number is equal to 9! × 722 × 27 × 27,704,267,971, the last factor of which is prime. The result was derived through logic and brute force computation. The derivation of this result was considerably simplified by analysis provided by Frazer Jarvis and the figure has been confirmed independently by Ed Russell. Russell and Jarvis also showed that when symmetries were taken into account, there were 5,472,730,538 solutions [10] (sequence A109741 in OEIS). The number of valid Sudoku solution grids for the 16×16 derivation is not known.\n\nThe maximum number of givens that can be provided while still not rendering the solution unique is four short of a full grid; if two instances of two numbers each are missing and the cells they are to occupy form the corners of an orthogonal rectangle, and exactly two of these cells are within one region, there are two ways the numbers can be assigned. Since this applies to Latin squares in general, most variants of Sudoku have the same maximum. The inverse problem—the fewest givens that render a solution unique—is unsolved, although the lowest number yet found for the standard variation without a symmetry constraint is 17, a number of which have been found by Japanese puzzle enthusiasts [11] [12], and 18 with the givens in rotationally symmetric cells.
