With a name like the Heavenly Ruler, it is easy to think that this slot machine is completely about the sacred measurement tools above. In fact, the theme of the game is about the sacred power rights of ancient China, revealing the spread of different symbols that represent the royal family, power and authority. These icons include a magnificent peacock, a symbol of the Ming Dynasty that ruled China from 1368 to 1644. These free heaven ruler slots may not be a good time for every rotator idea. In fact, the pious nature of the theme really makes the game feel a bit serious, and there are many online slots in other Oriental themes that bring some fun to this equation. Having said that, with its bold golden frame and royal purple background, the slots are still very enjoyable.
