Masterball (a.k.a. Duo Master) Vintage 1992 GeoMaster Black White Twist Puzzle 3” Ball Logic Game
The three basic moves are a north or south pole 45 degree turn, an equator 45 degree turn, or one of the four longitude 180 degree turns. Solve the rest of the puzzle first and then solve the poles by interleaving pole turns with pairs of longitude turns; or, solve the poles first and then as you do the rest maintain the poles solved (or in solved halves that can be fixed at the end). The NS pattern, where the top half is white and the bottom half black, is easy to visualize and not hard to do once you have worked with the puzzle a bit.
