Every board must be solvable, otherwise it wouldn't be much of a game. Generating a valid board |
|
|
|
|
turned out quite a bit more challenging than I thought. My algorithm is based in some heuristics |
|
|
|
|
and good deal of luck. |

To make things more fun, besides the marble matching rules, the board must be laid out in one of |
|
|
|
|
several pre-defined shapes of exactly 55 tiles. The algorithm can sometimes get itself into a dead |
|
|
|
|
end while placing marbles on the board. I experimented with backtracking, but the current version |
|
|
|
|
simply retries the whole thing with a different random seed. There are configurable retry limits |
|
|
|
|
as a failsafe. If the given template fails many consecutive times, the algorithm opts to switch to |

end while placing marbles on the board. After some experimentation I settled on a recursive algorithm |
|
|
|
|
with a heuristic and backtracking. There are configurable retry limits and max recursion / retry |
|
|
|
|
counter as a failsafe. If the given template fails many consecutive times, the algorithm opts to switch to |
|
|
|
|
a different template. Some templates are harder than others, and some random seeds just seem to |
|
|
|
|
have a problem. |
|
|
|
|
|
|
|
|
|
A workaround I added is called Sloppy Mode. When the algorithm can't place a marble, it may choose |
|
|
|
|
to add a new tile to the template, trying to keep the overall shape as tidy as possible. This may |
|
|
|
|
hurt game difficulty, but is generally much faster than retrying over and over. |
|
|
|
|
I added a few extra rules to the generation algorithm to make the boards harder: Vitae and Mors should not |
|
|
|
|
appear as the first few marbles to remove, since they tend to eliminate any choice; and metals start a few |
|
|
|
|
levels deeper still. This gives the player a lot more room to make a mistake in the beginning. |
