Blunder Annihilator: Chess Puzzles DEMO

NOTE: If it doesn't work, you can either switch your browser to an up-to-date Chrome or Chromium-based one, or use this link: https://html.itch.zone/html/9947739/index.html - it's just the direct link to the game.
Btw it works just fine on mobile, with the same restrictions regarding the browser.

And there is a Windows version below as well. I haven't tested if it works yet, though.

Gameplay:

In typical puzzles, move the pieces in the best way possible to win the puzzle. The puzzle elo is increased every time you win or lose a puzzle. It is randomly selected, but there is only ~1000 puzzles (only 200 below 1000 elo and then 600 between 1000 and 2000), so you will see repeated puzzles after multiple playthroughs.

In the special puzzles, make a move that you consider the best; to win the puzzle with a specific elo, you need to make at least as good of a move as a person on that elo would typically make. The situations presented are always situations where a person slightly worse would make a mistake and make a significantly worse move.

If you want to read more about how I generate the special puzzles, here is my blog post on Lichess.org: A novel idea for chess puzzles: no tactics, but avoiding blunders

This will start a mode where you have three hearts, and after three mistakes you'll end the game. Skipping a puzzle will cost you one life.

This will start a mode where you have infinite lives. You can skip the puzzle if you don't like it.

This will start a mode with the special puzzles. Other settings are like the "infinite lives" mode. There is only a handful of those puzzles implemented for now though (in fact if you're reading it just after I published it, there is probably just one puzzle. But I hope to upload a version with at least 9 of them).

In the finished version, there will be way more puzzles and way more settings to choose from. This is only a very early version of a demo.
