    Nice implementation. I've seen this puzzle before, does anyone know if it actually has an official name? Kind of reminds me of a variation on the tower of Hanoi.

    Not being able to repeat a successfully solved level sucks.

    It would benefit from that model that is popular nowadays whereby higher levels are unlocked by solving lower levels, and you can choose to play any unlocked level whatsoever.

    Very cool implementation of a classic puzzle (with a surprise on the last level that I haven't seen before.)

    Years ago I wrote some example Python to solve the same puzzle in another game (with spoilers for level 3):

    In some UK schools, this was the basis for a mathematics investigation for 11 year olds. Do the task for various numbers of frogs, records the results, and try to find a rule - then make a prediction for a certain number, and test it!

    A great introduction to the Scientific Method, and a fun activity too.

    Here's an example: https://spiremaths.co.uk/wp-content/uploads/Frogs.pdf

    As someone who is colorblind (Deuteranopia), the first level asks to swap the green and brown frog. With the hues used, I can’t tell the difference between the two frogs.

    Really enjoyed that! I was surprised by how fun it was considering how simple it seems. Definitely would love it to last longer.

    Really fun. Third level was harder than fourth.

    Really fun game. I was happy when I thought I screwed up the final level only to realize my screwup was the solution.

    I am so pleased I stumbled on this little game by chance. Really lovely. Well done. Keep it up

    On the last level, getting all the frogs converted to one colour and lined up on one side did not recognize the level as complete.

    Did I mess the direction or is this by design or is it an omission?

    Liked it. Especially level 4 with frog mutation ;) Definitely bookmarking it. Will there be any updates to add new levels?

    Claude Sonnet 3.7 has a hell of a time with this.

    Fun, but only lasts about two minutes. Could be interesting in 2d or with some other gimmicks added.
  • by dez11de on 3/27/25, 8:03 PM

    Stuck on level 8. Any pointers?
  • by Sontho on 3/29/25, 2:36 AM

    Loved it, it's so simple and difficult at the same time. Good job.
  • by H3X_K1TT3N on 3/27/25, 7:56 PM

    I clicked the frogs, but nothing happened. Am I doing it wrong or is it broken?

    I would like being able to press z to undo a move

    I get SSL_ERROR_RX_RECORD_TOO_LONG when trying to visit this site.

    cool. an interactive version of the knights and knaves book by ray Smullyan would be cool, as well. nice work.
  • by dgellow on 3/27/25, 9:23 PM

    That was a very cute puzzle, well done
