With just 2 beam splitters the number of beam paths can suddenly go from 2 to 8+ so this is a great addition for folks that are already OK with simple angles. I think with this add-on it helps to not try to use this is a very brightly lit room, it can be a bit hard after a lot of splits to see the light, and it's important to keep the game on a flat surface because it can fail to align and start 'missing' as the path gets complex if the game isn't on a very flat table.But it makes the game a lot more challenging, more than another order of magnitude of complexity is added to the game.
