| 1 | Simple Loop is a puzzle game where you draw a single loop that passes through all unshaded cells. |
|
| 2 | ||
| 3 | # Rules |
|
| 4 | ||
| 5 | Draw lines by dragging between unshaded cells. To win, these criterias must be met: |
|
| 6 | ||
| 7 | - There are no intersecting, branching, or dead-end lines. |
|
| 8 | - The loop must pass through all unshaded cells. |
|
| 9 | - There is only one loop. |
|
| 10 | ||
| 11 | The game will mark errors when found. |

| 13 | # Tips and Tricks |
|
| 14 | ||
| 15 | In every solved Simple loop puzzle, there are always 2 lines going through a cell. Therefore these basic deductions can be made: |

|
| 18 | ||
| 19 | Using the only one loop rule, this basic deduction can also be made: |

| 22 | ||
| 23 | -------------- |
|
| 24 | ||
| 25 | In solving harder Simple Loop puzzles, a bit of visualization must be made. Take a look at this common pattern: |

|
| 28 | ||
| 29 | Basic deductions are shown. |

|
| 32 | ||
| 33 | Now imagine there was no line (indicated by ×) in the above picture. Then, this is forced to be a single loop. Therefore there must be a line here: |
|
| 34 | ||
| 35 | [[/uploads/simpleloop-tips-2c.png | height=200px]] |
|
| 36 | ||
| 37 | You can do chains of deductions using this logic: |

|
| 40 | ||
| 41 | Imagine there was no line here. Then it is forced to be a single loop once again: |

| 45 | -------------- |
|
| 46 | ||
| 47 | Similarly: |

|
| 50 | ||
| 51 | Basic deductions shown. |

| 52 | ||
| 53 | [[/uploads/simpleloop-tips-3b.png | height=175px]] |
|
| 54 | ||
| 55 | With the cross mark shown above, the loop is forced to close with incomplete cells. |

| 61 | Another pattern that might show: |
|

|
| 64 | ||
| 65 | Basic deductions applied. |
|
| 66 | ||
| 67 | [[/uploads/simpleloop-tips-4b.png | height=150px]] |
|
| 68 | ||
| 69 | With cross mark shown, lines get forced like this, and the marked cell (in red) can only have dead-end lines, giving this: |

|
| 82 | ||
| 83 | Without a line here (×), the marked cell becomes a dead-end: |
