Hello everyone!
I believe most of you are spending time at home due to the influence of the outbreak of the Coronavirus. Staying at home for a long time period would be stressful, isn't it? Hence, I thought that it would be a good idea to introduce a traditional Japanese indoor game. I feel that if you love puzzles, you will probably love this game as well.
The name of the game is "Gomoku Narabe" or just "Gomoku." What you need
to play is the same as "Go"; a Go board, and black and white round
pieces. If you don't have them, don't worry. You can play it on the
internet.
It is said that the game was performed in the Nijo family (Japanese aristocratic kin group) in the mid-1700s and was transmitted to the private sector. If you attended the IPP36 Kyoto in 2016, you probably visited Ninja House (Nijo Jinya). There is the castle of the Nijo family next to the Ninja House.
I don't know how many people know about "Go", probably you may remember one scene of the movie "A Beautiful Mind." An American mathematician, John Nash, who won the Nobel Memorial Prize in Economic Sciences in 1994, loved playing "Go" very much.
Sorry, I got off track. Let's explain how to play "Gomoku Narabe."
The rules of "Gomoku Narabe" are simple. Each two players use black and white round pieces. Two people alternately place a piece on the board. To win, you need to line up your 5 pieces without gaps. You can line them up vertically, horizontally or diagonally. Let's have a look at the images below.
As you see at the inside red rectangular of image No.1, white pieces have already lined up 4, so black piece should be placed on the red circle mark, otherwise the black pieces will lose.
Image No.2 below shows the game has advanced a little bit from No.1.
There are 9 white pieces and 10 black pieces which means the next turn is the white piece. If you are the next turn, where will the next move go? The correct answer is where the red circle is.
The following images show what will happen if you didn't place a white piece on the red position.
On image No.3, the white piece seems like making 3 pieces in line. It looks good but wait. Please look at the V-shape light blue lines carefully.
If the next black piece is placed in the red circle position, the black will be in 4 rows. Do you think it's OK because you will be able to block the black pieces?
By placing a black piece, a 3 horizontal black pieces row was completed. (See image No.5)
Therefore, a black piece can be added to the horizontal row, in total it would be 4 pieces. (See image No.6) Oops, this is a very tough situation! That is because there are no white pieces on each ends of the row and nothing can stop the black row growing.
You see, there are 5 black pieces. So, this game is a black win.
"Gomoku Narabe" has various different rules, it depends on the area in Japan. Rule I, taught from my parents, was it is prohibited to line up two crossed rows of 3 lined up pieces. (See image No.8) The reason is those positions are easy to be made and a game will be finished very soon. However, some people think it is OK to arrange those rows. So, please note that there are several rules on "Gomoku Narabe."
I have attached some links of the online "Gomoku Narabe" game.

Before finishing this post, I will introduce a little trivia about "Go." Those black and white pieces look the same but actually, black pieces were made slightly bigger than white because the illusion makes the white pieces look bigger. However, I think mass productions made from plastic are the same size.
I hope you guys will have a good time at home.
