The section introduces the basic way of thinking of Reversi.

  1. In Reversi, it is important to take corners. Discs in corners are fixed discs that cannot be flipped. In addition, you can increase fixed discs as starting points them. Basically, if you can take, please take. If you do not want to be taken by opponent, please do not place your discs next to corners. If you place your discs diagonally next to corners, they are especially easy to be taken.
  2. In Reversi, it is important to have many places where you can place. If you take many in early and middle stages, there will be few or no place to place in final stage. Basically, please take fewer in early and middle stages. In addition, instead of simply taking fewer, please select a place to become like where you can place many more than opponent. If you make opponent's discs surround your discs and make opponent build walls on the outside, you will have an advantage.
