Bridges Logic Puzzle: Pontis

Pontis is a bridges logic puzzle — also known as Hashiwokakero or Hashi — built for players who appreciate clean deduction and thoughtful challenge. Every island shows a number. That number tells you exactly how many bridges must connect to it. Link all islands into one single network, without crossing bridges, and the puzzle is solved. HOW TO PLAY BRIDGES LOGIC PUZZLES • Islands display the exact number of bridges that must touch them. • Bridges run only horizontally or vertically, single or double, and never cross. • Connect all islands into one unified network to complete the board. WHY YOU WILL NEVER NEED TO GUESS • Proven unique solutions: Every single puzzle has exactly one valid solution. • Pure human deduction: The generator verifies every board with a solver that uses only logical techniques a human can follow. You are never asked to guess or use trial-and-error. • Intelligent hints: When you ask for a hint, the solver reveals the next logically deducible move, helping you learn advanced patterns rather than spoiling the board.
