Puzzle Cyclopedia[edit]

You can purchase the Puzzle Cyclopedia here: [1] I pulled up the amazon.co.jp page for that ISBN, but it has no pictures either. Phil Bordelon 11:59, 13 April 2006 (UTC)[reply]

Thanks for putting up the reference. I tried both a library search and a search in some online bookstores and could not find it, neither by title nor by ISBN. But since it is in japanese, it may have tried the wrong sources. Your anonymous IP 84.165.217.182 12:23, 16 April 2006 (UTC)[reply]

Comparisons with a Sudoku[edit]

So this is basically a Sudoku right? --71.105.21.125 01:16, 29 March 2007 (UTC)[reply]

No, this is very different from Sudoku. Try out each one and see that they both take logic, but different techniques. — Val42 03:02, 2 November 2007 (UTC)[reply]

Simpler puzzles[edit]

After I discovered this type of puzzle, I searched Wikipedia but didn't find this article. I created an article, Bridges (puzzle), and filled in the basic information. To avoid copyright issues, I created my own puzzle to illustrate the article. Someone found that there were multiple solutions, so I fixed it. Since the Bridges (puzzle) article has been shown to be redundant, I have placed these illustrations of a simpler puzzle with its solution over on this page. If there are multiple solutions, please post a message here, with hints as to where they are.

Also, if someone objects to further illustrations of this type of puzzle on this page, then bring it up on this discussion page. I think that they help for someone new to this puzzle. — Val42 03:02, 2 November 2007 (UTC)[reply]

Alternate solution for the given "simpler puzzle"?[edit]

Is it just me or is there another solution for the "simpler puzzle" given? I'm talking about this puzzle: http://en.wikipedia.org/wiki/Image:Val42-Bridge1.png Specifically, the group of islands in the lower right corner. You could have two bridges from the 3 to the 4. Then one bridge from the 4 to the 2, and one bridge from the 2 to the 1. In essence, instead of having two bridges going 3-1 and 4-2, you have two bridges going 3-4 and 1-2. --24.46.164.83 08:45, 8 November 2007 (UTC)[reply]

I checked it out, and this is also a possible solution. I have plenty of experience in solving these, but this is the first real one that I've created. I'll revise it again to get rid of this problem then upload a new set of diagrams. Until then, look for problems in the other quarters of this puzzle. — Val42 03:43, 9 November 2007 (UTC)[reply]

That didn't take nearly as long to fix as the previous time. Thanks for telling me the alternative solution because that saved me a lot of time. Please let me know if there are any other alternate solutions found by giving the details on this talk page. — Val42 04:36, 9 November 2007 (UTC)[reply]

No, it looks good. Once I saw the alternate solution, I checked the rest of the puzzle, but that was the only alternate solution I could find. ;)

Another alternate solution to the "simpler puzzle"?[edit]

I think I've found another alternate solution to the "simpler puzzle". It focuses on the group of islands in the middle-right, clustered around the 5. Instead of having the 5 send 1 bridge up and 1 bridge right, have it send 2 bridges right (to the 2). This would satisfy the 5 and the 2, but leave both 3's with a free bridge each. This would be satisfied, of course, by having them connect to each other. Mavwreck (talk) 21:36, 13 August 2010 (UTC)[reply]
