I usually play it on here: https://gridgames.app/battleships/

In this version, the field can be prefilled with some ship parts

Nice collection of puzzles. But the ads on this are bloody awful. Can't even pay to get rid of them. What a pity.

TIP: Don't sign up! It doesn't give you any benefits, and you still can't get rid of the ads.

Cool to see this here. I like the design and instructions.

I’m publishing a paperback book of (numeric) logic puzzles:

having played a lot of this puzzle on https://www.puzzle-battleships.com/ ... I'd love a couple QoL improvements, one from there and one to be better than that one

- counters for columns/rows would be a nice idea to steal

- inverse control (so, lmb for ship) would help with not interfering with default behaviour, for people switching to/from different puzzles

Also ship helper really should come with each type on its own line - your listing is harder to parse than on that website

I think there's a bug. If we have two two-length ships, that are next to each other in a connected in an "L" shape, it's not possible to define it on the board.

You can't have that configuration: ships must not touch, even at diagonals.

This implementation seems to work a little better: https://www.puzzle-battleships.com/

What makes that one better in your opinion? I've tried both and I think they're both OK.

"Ships can't touch diagonally."

But it lets you do it and then tells you it's wrong at the end.

When the "4" has a strikethrough, the strike is almost impossible to see.

"Ships can't touch diagonally." is a rule qualifying valid answers, not what can be drawn on the diagram

Since that instruction's easy to miss - I added an immediate error message / red dot if two ships are placed diagonally from each other: https://lukerissacher.com/battleships

The way the shapes draw themselves — e.g. the curves — seem to indicate if a shape is at the end, in the middle, etc. Is that intentional?
Zanni 10/25/2024||
It seems to be intentional. (I was confused by this at first, too). If your starting grid contains, e.g., a dot, you can safely assume it's a one-ship. But if you add a ship, the initial state is a block that resolves to a dot or end as appropriate when you complete it.

Yes, it’s an additional piece of information that is vital for some puzzles.

I got a puzzle with (at least?) two valid solutions, but one of them is "wrong" and the game refuses to accept it.

Boo.

What this needs is a daily puzzle and an easy way to share it in text format, a la Worlde or Domino Fit...
