Maybe make them look like rocks or brick walls?
A more minimalist approach might be a small "x" in the center of each square.

He is saying cut out the concept of lives entirely. It seems like a distraction. What is the point of lives?
Ah sorry I misunderstood! The concept of lives actually arose from a lot of playtesting and valuable feedback during the beta. Many players were feeling that there is no real 'cost' to brute-forcing the exploration of every possible path on the board. Granted, the time complexity of doing so is really high. But from an emotional standpoint, beta testers seemed to appreciate more often than not the adrenaline rush tha…

Thanks! Really appreciate the support. If you're up for a real challenge, check out this puzzle: https://echochess.com/game.html?game_mode=DAILY&level_type=E... Looks super innocent but has already stumped a GM. Happy to give hints if you'd like. gl :)
ECHO CHESS Mar 21 (E) ♟ 2:26 sec 1/8 tries 14 moves Fun little logic puzzles for sure. Nice job! edit: HN stripped the emoji but I did solve it, lol

What a great idea, quite addictive.
Glad you're enjoying it! Thanks for the support. Any suggestions for improvements you'd like to see?
So is the idea that the dark red squares are inaccessible and you just can't move to them? I spent way too long trying to figure that out. I was stuck thinking along the lines of not being able to to move into check, even after transformation to another piece.
Also, on Firefox for android, you can't move pieces downward. The browser hijacks the "drag down" gesture and refreshes the page.
The pull to refresh has been very broken since forever. Apparently they enabled it by default in the latest version because it was "very stable" but I'm not so sure...

Ah I see, thanks for the explanation!
If you think about the chess board in abstracted terms, you can actually map an echo chess puzzle to a graph theory problem. First, you disregard any empty squares, and you consider each piece-square as a node, with its neighboring nodes being any node that can be reached from this node using any number of >0 valid moves without reaching any interim node on the way.
Using that process, you can now convert an entire echo chess board into a graph where each chess piece is a single node. Now you can ask the question, "what is the objective of solving an echo chess puzzle in terms of this graph?"
It turns out that since the goal is to clear all pieces of the board, and in order to clear pieces we have to reach their corresponding square, then in graph terms our goal is to visit every node. However we can only visit every node once at most (because once a piece is captured, it is taken off the board).
In other words, an echo chess puzzle is the same as "visiting every node on the graph exactly once". That's the HPP which is NP-complete, and if you're looking for the shortest HPP, it's even NP-hard.
TL;DR: brute-forcing as a player is not the optimal strategy.

Super fun! THanks. 11 moves! and now I need to wait 24 hours! :-( You know what would be cool: flashing a trivia fact beneath the board with each move. Maybe a chess history fact? EDIT: Man - epic is no joke!... LOVE this.
lmaooo your edit killed me @samstave. Glad you're enjoying echo chess! and yes, some of the daily epic puzzles can be brutal :) I think it might help to start with a certain strategy in mind. were you able to hone in on a strategy for that one yet? lmk if I can help
This would make a really cool watch-face for idling....
EDit: on second thought...
I cannot figure out how to kill the black pawn above me..

Unless I missed, maybe some description of the goal, in the beggining it wasn't quite clear to me that the goal was to capture the whole pieces, and only a subset of chess rules are available.
any ideas how to improve that in terms of text or visuals for further clarity?

No help thanks - I've only just discovered this and I like it breaking off the slag from my rusty gears. This would make a really cool watch-face for idling.... EDit: on second thought...
