Logic puzzles have a unique way of captivating our minds, challenging us to think critically and creatively. One such puzzle that has gained popularity over the years is the Snake puzzle, also known as Tunnels. This seemingly simple grid-based game can quickly become a captivating test of your deductive skills. In this blog post, we’ll introduce you to the rules of the Snake puzzle, provide some tips for solving it, and explore why it’s a favorite among puzzle enthusiasts.
The Rules of Snake Puzzle
Here are the rules for Snake logic puzzle. Like many of the very best and captivating puzzles, the rules are deceptively simple 🙂
The Grid
At first glance, the Snake puzzle may appear as a blank grid. However, it’s far from empty. The grid consists of two black squares. The key components of the grid are the starting and ending squares. Your goal is to connect these two points using a continuous path.
Here is a completed grid:
The Clues
The outer perimeter of the grid contains numbers.. These numbers provide crucial clues to help you navigate through the puzzle. Each number indicates how many squares in that row or column should be included in your path. You will mark these squares as you complete the path. Your task is to determine which squares should be filled to form the correct path from start to finish.
Note: These numbers need not be completed in a single path. For example, the number 5 represents 5 cells included in the path in total and might be broken down into a path of 4 and 1 (as we can see in the image above).
Snake Movement
The path you create must follow certain rules:
- The path must be continuous, forming a single, unbroken line. The path may join adjacent cells which are next to each other sideways or up and down, but never diagonally.
- The path cannot cross itself or overlap at any point.
- The path cannot touch or cross any blackened squares. These are obstacles you must navigate around.
- The path must connect the starting and ending squares, ensuring that the numbers on the grid’s outer perimeter are satisfied.
Tips for Solving Snake Puzzles
Solving Snake puzzles can be both challenging and satisfying. Here are some tips to help you tackle these intriguing brainteasers:
1. Start with the Numbers
Begin by examining the numbers on the outer perimeter of the grid. These numbers are your road signs, guiding you on which squares to include in your path. Focus on rows or columns with the highest and lowest numbers first, as they provide more definitive information.
2. Use Deductive Reasoning
As you progress, remember that your path must be continuous. Use deductive reasoning to eliminate possibilities. If a particular row or column already has the required number of squares filled, you can confidently mark the remaining squares as obstacles.
3. Beware of Dead Ends/Odd Cells
Keep an eye on the clue numbers and make sure you don’t end up with any odd cells or dead ends.
4. Be Patient and Persevere
Snake puzzles can become increasingly complex as you advance. Don’t be discouraged if you hit a roadblock. Take a step back, reevaluate your choices, and keep trying different approaches. Patience and perseverance are key to conquering these puzzles.
5. Trial and Error
Sometimes, it’s necessary to make educated guesses. Just be sure to mark these guesses clearly and be prepared to backtrack if they lead to contradictions. Trial and error can be a valuable tool when used strategically.
