This digital dice could definitely make turns easier if you’re a regular settler or more of an expansion-pack-needed-for-large-gatherings-on-rare-occasions type player. From joshi on Hackster.io:
I love a good game of Settlers of Catan, so why not build a digital dice? I first used seven red leds, when I realised you need two dices for Catan. I decided to use an LCD display.
