Detailed Game Introduction

One line only: dot to dot follows the Euler path tradition: connect all points/edges with a single, unbroken stroke. Boards introduce bridges, forced turns, and parity tricks that require careful route planning and backtracking discipline.

Gameplay Strategy & Walkthrough

1. Degree count: Start at odd‑degree nodes (0 or 2 exist for Euler trails); they suggest endpoints.
2. Bridge first: Draw mandatory bridges early so you don’t lock them out later.
3. Avoid isolating: Don’t complete loops that strand unvisited edges.
4. Look‑ahead: Test two moves mentally; backtrack early when isolation appears.
5. Symmetry: Use symmetrical halves to mirror partial routes.

Controls Guide

• Drag to draw along segments; undo/clear via UI.

Frequently Asked Questions (FAQ)

• Q: I end one step short — why?

  A: You likely started at a wrong endpoint; try an odd‑degree node instead.

• Q: Are crossings allowed?

  A: Only along provided segments; no freehand crossings.

• Q: Any hint system?

  A: Many builds provide hints or highlight bridges.
