★★★★☆ 面白い interesting. good part. ルール説明がよく出来ている 練習問題みたいな形で習うより慣れろ 広告の閲覧時間が短いのもgood. 課金で、広告を消す料金も安い ただしバグが数十局に1回起きる However, a bug occurs once in dozens of stations. 以下 bad part. 石の数に間違いが発生した場合、その位置をクリックするとplease waitからの強制負け Wrong number of stones during a game. 48 is correct.(Occasionally, during a game, a total of 44 stones.)else In addition, there is a sudden defeat processing.
★☆☆☆☆ To test a single number, you need at least 10000 credit per month for EU or 3000 for US. Yet what you first get for free is 100, meaning it is close to nothing. OK, OK I got something, so I give you stars in the same way; 100/3000 is 1/30. 5 stars of 1/30 is my evaluation. :)
