### Last-Minute d6 Dungeons: Side Exits from Tunnels

Readers may have noticed that the Wednesday installment of the Last-Minute d6 Dungeons (links at end of post) reduced everything down to one (semi-) drop dice method to determining exits, but there was something missing. When rolling for side exits from tunnels, the drop dice method only tells you how far along the tunnel section each exit is, but doesn’t tell you which side of the tunnel it is.

I was aware of this, but left it out for a reason: I wasn’t happy with the methods I came up with. There’s basically four obvious methods of dealing with it.

1. Roll 1d6 or flip a coin for each exit to determine which side.
2. Don’t roll again. Just pick the side that makes the most sense (no connecting back to already-mapped areas, for example.)
3. Make the exit roll do double duty. If d6 result is odd, exit is on North or West side of tunnel, whichever makes sense. If d6 is even, exit is on South or East.
4. Same as #3, but only for first exit in tunnel section. Second exit will be on the side alternate, and third exit will be on the same side as first exit.

Method #1 adds extra dice rolls, right after we trimmed some out, so it’s no good.

Method #2 is fine as a general principal to modify random results where needed, but the whole point is to make a random generator.

Method #3 is a bit predictable. For example, a loose (no match) d6 result of 1 is a side tunnel, but under this rule, all side tunnels would be on the same side of a tunnel. Method #4 fixes this a little, but still could be more random.

But since we are also rolling dice of different colors (two light-colored, one dark-colored,) we could make use of that to modify Method #4.

1. If the dark d6 result is odd, the first exit is on the North or West side of the tunnel. If the dark d6 is even, the first exit is on the South or East. Second exit will be on the opposite side, and third exit will be on the same side as the first. Modify any result that would lead back into already-mapped areas.

If we really feel the need for more randomness, flip the second or third exit to the alternate side if the d6 result is the “opposite” of the dark d6. In other words, if the dark d6 is even but the d6 for the 2nd exit is odd, that exit is on the same side of the tunnel as the first exit.
