Sasiraengi is a traditional folk game developed in Dongjeom-dong, Taebaek-si. From olden times, there was a copper mine in Dongjeom village. This village was once called Tungjeom, an old word for copper; later it was changed to the Chinese character Dongjeom. Sasiraengi arose in this region 3∥4 centuries ago. It is a sort of gambling game played with coins. When people stayed up all night in a deceased persons house mourning a death, or when soldiers were on night duty, they played sasiraengi. Sasiraengi is similar to 'gopseochigi' of the Gwanseo region, but is different in the songs that are used. Villagers played this game during ceremonies such as wedding, 60th birthday parties, 60th wedding anniversaries. Some people would spend everything they had playing this game. The reason that we know sasirengi was made 3∥4 centuries is that the words used to play it show that it already existed during Byeongja Horan. Sasiraengi, which was popular in Tungjeom, was also called Cheoltoi, and is a unique game, found nowhere else in Korea.

Sasiraengi is a unique folk game, popular in the vicinity of Dongjeom-dong, Taebaek-si. It was not entirely unknown elsewhere, however.

Sasiraengi is a game played with 24 coins numbered from 1 to 10: three nips from 1 to 4, two nips from 5 to 10. One group consists of five people. Those designated 'kkojikkun' shake 24 coins with both hands, and then distribute 3 coins to four gamblers in two turns. Gamblers, shaking the coins, sing comic and humorous songs. The words of the songs are very sarcastic. Of course, there are words handed down from old times, but others have been added over the passage of the years. Sounds of these songs are similar to Jangtaryeong, and are also similar to gopsoechigi of the Gwangseo region. Sasiraengi is not a game which can be played quietly. Noise is an integral part of the fun. If a coin appears with the number '1' on it, it is thrown into a tray to the accompaniment of a suitable song. If '3' appears, another song is sung. It continues whenever different figures appear... At this time, if the other side shows a coin with the number '2', it can be caught by his own letter '2', but show another coin instead. If the other player has the same figure that is presented, he can get it. If not, he must present another coin from those he holds in his hand. All six coins are distributed. If most of them are not caught, the player may emerge as the 'doksu' (winner), and take all the prizes. The words of Sasiraengi can be made improvisational by the players themselves. Sasiraengi then, is a folk game, usually played during family ceremonies in which many people are gathered, and is famous for its long words.
