How to play

Learn the objective before jumping into a new run.

  • Swipe left to begin a puzzle, then tap or click squares to discover how the board changes.
  • Clear every non-black square to complete the current puzzle.
  • Swipe right to reset the puzzle or revisit an earlier one.

Controls

Keyboard and touch instructions for this game.

  • Tap or click a square to test how the board reacts.
  • Swipe left to start or move to the next puzzle.
  • Swipe right to reset the current puzzle or revisit an earlier one.

Tips

Small habits that can improve your score.

  • Start with the most isolated squares so each reaction is easy to read.
  • Reset early when the board state no longer matches a clear plan.
  • Remember successful patterns: revisiting a solved puzzle does not increase the reviewed progress score.

FAQ

Quick answers for common questions.

Can I play on a phone?

Yes. Black Hole Square supports both touch and mouse input in its responsive canvas surface.

What counts as a score?

Only a newly solved native puzzle is reported through the reviewed Bridge.

Why does the score not rise when I replay a level?

The package deliberately tracks unique solved puzzles rather than arbitrary revisits.
