I’m designing a board game which uses hexagonal tiles (hex[es]) to form the game area the players move about in. There is a single hex which is the players starting point, and one “layer” of hexes around that centre one. This is the starting layout:
After this, players can add new hexes to the structure in any direction. The only rules are they fit in to the hex ‘grid’ and they touch an existing hex. Therefore they do not need to fully complete concentric layers, they can go one direction in a line of hexes for example.
I would like to introduce a mechanic that targets a random hex, and this is where I’m struggling to come up with a good way of determining that random hex.
Ideally, the method should give an equal chance for any hex to be targeted; and it should only use components which are generally found in board games. It would be very easy to do this with the addition of a mobile phone, for example, but I would like to try and keep this classic. Common components are items such as dice, spinners, tokens, cardboard components, etc. Feel free to suggest anything that might help. The other requirement would be that the process is not overly complicated - but as that’s subjective I’m open to anything.
TL;DR Is there a method of choosing a random hex from any number of hexes, in any formation, using common board game components?
