Battleship Solitaire
- mrec 9y agoIt's missing some really basic instructions, i.e. clicking cycles between "not marked", "marked as water" and "marked as ship". Just saying "Click squares to set where you think the ships are." is singularly unhelpful.
- Treblemaker 9y agoI found the process of discovery (including the ship orientation hints mentioned below) was part of what made it enjoyable. Of course, after about five minutes the rules and strategies have become apparent and it does become truly mindless...
- Treblemaker 9y agoAnd yet I keep playing it....
- kazinator 9y agoHelps to go to a bigger square. I just did 10x10 and am quitting.
- starshadowx2 9y agoYeah, after a few minutes of playing and figuring it all out, it's become super easy to do a 15x15. A timer would be really great to see just how well you can do and to push yourself for better times. I think I've gotten 15x15 to always under 25-30 seconds
- starshadowx2 9y agoYou can also click-drag to set water, which isn't mentioned.
- macrael 9y agoA fun little game, it seems like there are some solutions that are ambiguous though and it only allows one as the solution.
- toast76 9y agoFun puzzle, but I had the same problem. Example: https://imgur.com/a/t4T5l https://imgur.com/a/t4T5l The solution is valid, but the expected result has the two dots in a different position. EDIT: I just realised, although it isn't clear in the instructions, that the shape of the boats is an implied part of the solution.
- luminiferous 9y agoNot so, but only because of rules about the notation that are not stated. The dot in the top left (which I am assuming is one of the initial positions that the game gives you, from the darker background color) is, due to its shape, necessarily a size 1 ship. It does not continue downwards. Similarly, the initial position on the left-middle shows it going upwards. The initial positions not only tell you that there is a ship going through that location, but also in what direction, if it's the end of said ship.
- twiceaday 9y agoHere is one I ran into that is clearly wrong: https://i.imgur.com/1leWCg9.png https://i.imgur.com/1leWCg9.png
- QuadrupleA 9y agoHey, author here - ships can't touch diagonally.
- sparky_z 9y agoYeah, maybe you should put that closer to the top. It took me 5-10 minutes to realize that I hadn't scrolled down quite far enough to see that extra rule. It's especially easy to miss if you're already familiar with the original 2-player version of Battleship, since there's no such rule in that game.
- flipacoin0 9y agoThis is great! I'd love to see it as part of Simon Tatham's Portable Puzzle Collection [1] [1] https://www.chiark.greenend.org.uk/~sgtatham/puzzles/ https://www.chiark.greenend.org.uk/~sgtatham/puzzles/
- 8_hours_ago 9y agoThis reminded me of Tents [0], which is one of the games in Simon's puzzle collection that I reach for while waiting for code to compile. Someone should add this game! Simon has very good developer documentation [1], and the code is very cleanly written C. Seriously, every C developer should take a look at it, it is inspiring [2].

- twiceaday 9y agoThis puzzle is a bit janky and is able to have multiple solutions but only accepts one [1]. I recommend checking out similar-style puzzles called "nonograms" which are widely available. [1] https://i.imgur.com/1leWCg9.png https://i.imgur.com/1leWCg9.png
- vishvananda 9y agoThat solution is not correct. Your boats on the top right are touching. They cannot touch, even diagonally

- CapitalistCartr 9y agoThis looks to be as addictive as 2048. I still play that one. https://gabrielecirulli.github.io/2048/ https://gabrielecirulli.github.io/2048/
- kazinator 9y agoSolitaire Battleship is very similar to "nonogram puzzles", e.g. https://en.wikipedia.org/wiki/Nonogram https://en.wikipedia.org/wiki/Nonogram https://www.puzzle-nonograms.com/ https://www.puzzle-nonograms.com/ You have a grid where the rows and columns are labeled with how many squares there are (additional info: you get splits, like "3 2" means there is a run of 3, and 2). You have to work out the image. This Solitaire Battleship is hard though, because of the sparse placement and has other elements to it. There is a similarity to this and the reconstruction of an image from projection data. Horizontal and vertical histogram data has been used for OCR. (You can recognize a glyph from the histogram patterns.) This is also related to the backprojection technique used in CT scans to reconstruct the slice images.

- vinchuco 9y agoI was confused at first, but by 'mistakes' the author only means false positives, and not false negatives. I guess... "Anyone who has never made a mistake has never tried anything new"
- alejohausner 9y agoFor a while, the NY Times Sunday mag had just this kind of puzzle, in print form.
- jack9 9y agoSimpler version of Nonograms. Crossme Nonograms is one of the best non-sudoku mobile games that is somehow more fun.
- starshadowx2 9y agoI've been able to solve all the ones I've gotten so far, but I'm stumped as to how to do this one (https://i.imgur.com/6qmZX7z.png https://i.imgur.com/6qmZX7z.png) without 1. trial and error, or 2. using the checking tool to see what I did wrong (cheating in a sense) I feel like there's a strategy that I'm missing here. I'm just not sure what my next step should be, which would probably help me get all the rest done.
- starshadowx2 9y agoActually nevermind, it's obvious now that the 5-piece was in the 5 row.
