A free Reversi (Othello) game that you can play instantly on the web. It features AI matches, online matches, and a Reversi board mode that simply displays the digital board.
オセロAIの難易度は、初心者向けのやさしい設定から人類最強レベルまで、幅広く用意しています。
本サイトで一番人気の中級AIはおおむね1手先、そして上位のAIは8手以上先の局面まで想定し、最善の手を探す仕組みです。内部では「ビットボード」と呼ばれる仕組みを活用することで、賢く高速なオセロAIを実現しています。
このAI対戦モードでは、これまで200万局以上が遊ばれていました。上位のAIになるほど、勝てる人の割合も実際にじわじわ下がっています。例えば、上位3.5%%ほどの強者だけが挑める隠しコンテンツ《🌈伝説AI》では、勝率はわずか27%%前後にとどまっています。
The reason I started creating this site was that I once had trouble finding a site where my family could play Reversi together.
During the development process, I made it a point to interview actual users and improve the site based on their feedback. Since then, I have made many improvements, such as adding a unique online match mode and powerful AIs, and many people both inside and outside the university have played it.
I welcome feedback, so please feel free to share your thoughts.
