Chess puzzle, but you are what you capture

Original Article ↗ Hacker News Discussion ↗

Gameplay & Core Mechanics

  • Player always controls White; capturing a piece turns the player into that piece.
  • Goal is to clear the board in as few moves as possible; you can capture your own pieces.
  • No castling, promotion, or en passant; some commenters note this feels “less like chess” but accept it as a variant / “chess‑like.”
  • Some are uncomfortable with having to capture the king and with checks not mattering.

Puzzle Design & Difficulty

  • Many find the puzzles clever, minimalistic, and surprisingly deep, with strong replayability.
  • The “Epic” daily puzzles are repeatedly described as very hard, sometimes even stumping strong players.
  • Several users ask for clearer indication of optimal or “par” solutions; concern that giving exact optimal move counts may over‑hint the solution.
  • Lives (hearts) are polarizing: some enjoy the tension and anti‑brute‑force pressure, others see them as unnecessary or confusing.

UI, Rules Clarity & Accessibility

  • Inaccessible red squares confuse many; they want explicit markings (X, texture, “walls”) and/or clearer rules text on the board.
  • Initial goal and rule explanations (no promotion, what obstacles mean, capturing the king) are viewed as incomplete.
  • Requests for: replay/rewatch of finished games, move list, better end‑screen options to retry or browse more puzzles.
  • Mobile issues reported: drag‑down conflicts with browser pull‑to‑refresh; preference for click‑to‑move over drag on touch devices.

Sound, Performance & Platforms

  • Music and sound effects are generally liked, but several argue that music on a web page should default to muted, partly for bandwidth.
  • Others feel sound on by default is fine for a game.
  • The site is a PWA; users request native mobile apps, especially iOS.

Zen Mode & Daily Format

  • Zen Mode is an infinite, procedurally generated, timed mode built with an ML model; appeals to blitz‑style players.
  • Some dislike the timer and want a relaxed, untimed experience.
  • A few feel the daily‑only format plus very short playtime makes it harder to form a habit; others point to Zen and archives as solutions.

Accounts, Privacy & Technical Issues

  • Strong pushback against requiring a phone number to access past puzzles; users worry about privacy, data handling, and necessity of login for free content.
  • There are calls to use email/username or third‑party auth instead, or avoid collecting personal data altogether.
  • Site experienced outages and wrong‑puzzle issues under heavy traffic (“HN hug of death”), later reported as fixed.
