Blunder Annihilator: Chess Puzzles DEMO

Update (March 2025):

Just so you know, I haven't abandoned the project. I am working on making a completely new GUI with new, more modern and less mobile-like design. I also want to create a Steam page soon (next two-three months, though we'll see), for which I need a nice looking capsule image and a trailer, for which I need a functional GUI and probably more than a few example puzzles. So there is a whole lot of work to do. I hope I will be able to write a devlog soon to explain my design decisions and the evolution the GUI went through, and in the future also the way I make the puzzles.

I'd also really want to share a list of feature I'm planning to implement - outside of different modes, I plan to have statistics and a roguelike-like evolution tree to guide your learning. Something I was also thinking about is an interactive opening explorer/trainer, in which you play the game from the beginning and if you make a move that puts you in a very bad situation (like if you use Bangcloud opening or if you fall into a scholar's mate), you lose quickly, which teaches you not to do that move. It's a bit more chaotic approach than usual theoretical one.

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.
