What This Game Is

Bridges is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.

Connect all the islands with a network of bridges.

How to Play

To place a bridge between two islands, click the mouse down on one island and drag it towards the other. You do not need to drag all the way to the other island; you only need to move the mouse far enough for the intended bridge direction to be unambiguous. (So you can keep the mouse near the starting island and conveniently throw bridges out from it in many directions.) Doing this again when a bridge is already present will add another parallel bridge. If there are already as many bridges between the two islands as permitted by the current game rules (i.e. two by default), the same dragging action will remove all of them.

Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.

Beginner Tips

  • Start with the area that has the strongest clue or the fewest legal options.
  • Use marks, notes, or temporary indicators if the puzzle supports them.
  • Try to preserve flexibility instead of committing too early when multiple moves look possible.
  • If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
