Hah! Makes me feel better about struggling with level 3.

Oh that's cool - I had no idea it was used in UK schools, thanks for sharing this!

Thanks! Might play with more levels if people keep enjoying it.

Ha, you're not the first to say that about level 3! I think I accidentally made the difficulty curve a bit wonky there. Glad you had fun with it!

I'm curious about the difficulty curve. As long as the puzzles take the form "group of left-facing frogs - empty pad - group of right-facing frogs", they'll all have exactly the same solution. If you can do level 2, you can do level 2222 without needing to come up with any new ideas.

This kind of blocks the notion of a "difficulty curve" - it's just a flat line.

Level 4 is different, but I'm guessing the reason people say it's easier is that the frogs on the left never need to interact in any way with the frogs on the right. You can just march your left-frogs onto the transformer, see them turn around, and march them back to their ultimate destination, then repeat the process on the right.

I don't think there's any solution that would allow a frog to jump over the transformer, so you're essentially required to do this - all frogs must make their way to the transformer, transform, and go back home - although you can make it look more or less complex. This essentially gives you two copies of the "level 3 and below" puzzle, one on the left of the transformer and the other on the right.

Glad you found it cute. Was aiming for that mix of simple looks but tricky solution.

Thanks! Really made my day to hear you found it by chance and enjoyed it.

Good call! The facing direction was meant to help, but I can see how the colors could still be tricky. I’ll look into making it clearer — appreciate the feedback!

Glad you liked it! That last level twist was a fun addition — I wanted to keep things interesting. Your Python solver looks awesome, I’ll definitely check it out. Always cool to see different approaches to the same puzzle!

Thanks! I’m not sure if there’s an official name for it — I originally saw the game a decade ago at my university and just recently decided to build my own take on it. It definitely has some Tower of Hanoi vibes. Let me know if you find an official name for it!

Hey everyone, I’m the author—really appreciate all the feedback here. If you want to follow along with what I’m working on, I’m over on Twitter: https://x.com/rv_labs. Thanks again!

Well, I burst out laughing when I jumped on the transformer lily pad. I assumed there was a trick, but not that.

Quite cute diversion.
