“cyclomancy”
Divination with some revolving device, such as a wheel or revolving circle: At the fairgrounds, Jack wanted to go to the large rotating circle with messages and signs on it, and by the method of cyclomancy, see what his future prospects would be.

Sometimes people wonder if this is the same system that is being used by modern weather forecasters to predict current weather conditions.
The “wheel-of-fortune” found at carnivals or on the TV “Wheel of Fortune” are based on this concept. Cyclomancy has survived in various parlor games, such as “spin the bottle”.
