# Filling in an 8x8 minesweeper grid with mines (Day 2: Diagonal Reverse Synesthesia)

Note: This is based off of Day 30 of the Minesweeper Advent Calendar on heptaveegesimal.com

So my first minesweeper puzzle did not go so well. I will try to do better today.

First off: This is a torus puzzle. This means that a box, say R1C4 will be affected by mines on R1C3, R1C5, R2C3, R2C4, R2C5, R8C3, R8C4, R8C5 (since this is an 8x8 minesweeper grid) (if this were regular minesweeper)

You might note that each number will have a specific color. Here are the 2 different mechanics for the numbers:

Number: Tells you how many mines there are on the 4 orthogonal neighbors to a tile (for example, in this puzzle, R1C4 will have the orthogonal neighbors R1C3, R1C5, R2C4, and R8C4)

Color: You'll have to deduce this yourself, however a hint: A red 3 would indicate that there are 3 mines on the diagonal tiles and all orthogonal tiles are safe.

Mines used in this puzzle: Single (1), anti-mine (-1)

No numbers are missing. No mines aren't accounted for.

$$\color{red}{-1}$$ $$\color{green}{4}$$ $$\color{green}{-3}$$
$$\color{red}{-3}$$ $$\color{green}{-2}$$ $$\color{green}{1}$$ $$\color{blue}{7}$$ $$\color{green}{-2}$$
$$\color{green}{-3}$$
$$\color{green}{0}$$ $$\color{blue}{6}$$ $$\color{red}{0}$$
$$\color{green}{0}$$ $$\color{red}{-2}$$
$$\color{green}{-1}$$ $$\color{blue}{2}$$ $$\color{blue}{5}$$ $$\color{green}{3}$$
$$\color{green}{0}$$ $$\color{blue}{-3}$$ $$\color{green}{-2}$$
$$\color{green}{1}$$ $$\color{green}{2}$$ $$\color{green}{-1}$$

also technically it's already time for a day 2 because SE counts days in UTC (it's 1:50AM there)

• I think the red -4 on the left contradicts the hint about the colours, it has to have a -1 on an orthogonal cell at R2C8 Commented Oct 25, 2023 at 2:12
• @BeastlyGerbil Oh right right, I'll fix the number when I wake up tomorrow Commented Oct 25, 2023 at 2:42
• Don’t worry if your puzzles don’t always go well @CrSb0001– they’re still very interesting and definitely appreciated! Commented Oct 25, 2023 at 4:30
• If numbers count mines on the orthogonal tiles, how can a red 3 mean all orthogonal tiles are safe? Commented Oct 25, 2023 at 20:45
• I think that makes more sense. Commented Oct 25, 2023 at 21:28
