Hollow Earth Expedition uses the Ubiquity rules, which were also created by Exile Game Studio. The main feature of the system is its use of binary dice pool rolls to determine success. Under the default rules, each even number rolled counts as a success, while odd numbers count as nothing. Odd 'nothings' do not cancel out even 'successes', making dice rolling quick and simple. This binary system has also led to the development of special Ubiquity Dice, which are not detailed below.
