形四は、1972年山本蛍（雅方第一世名人）が、中学校のときに考案した ゲームです。その後、1976年に友人の大和団次郎がパソコンゲーム用に 簡略化したルールを提唱しました。それが本ゲームです。 https://dnjiro.hatenablog.com/entry/keisi ■遊び方 　下の番号をクリックすれば、形四の盤面が表示されます。 　黒駒●を移動させて正方形を作ってください ■１．形四のルール １．交互に縦横斜めに１コマ移動させます。 ２．正方形ができたら勝ちです ３．＜禁手＞直前に移動したコマを元の位置に戻すことはできません 　 ■２．駒の移動 ・黒駒●をクリックし、移動先をクリックすれば、移動できます ・ドラッグでも移動できます ・あなたが黒駒●を移動させれば、PC（アプリ）が白駒〇を移動させます ・どちらかが正方形ができるまで、続けてください ■３．先手、後手の交代 ・正方形ができたら、「交代」ボタンをクリックしてください。 　先手、後手を入れ替えてもう一度勝負します ・２回勝てば、そのゲームの勝利です ・ゲーム番号をクリックすれば、何回でも勝負できます ・「ー＋」をクリックすれば、９６番まで勝負できます
