The title of this game translates roughly from Japanese as 'Seven Pairs - 10,000 Yen Goes, Another 10,000 Yen Comes'.

The subtitle is a play on a Japanese proverb 'Ichinan satte, mata ichinan', which means 'One misfortune goes, another one comes'. An 'Ichiman' is a 10,000 yen note, the highest note of Japanese currency.

In mahjong, a 'toitsu' is a pair of like tiles waiting for a third like tile to create a three-of-a-kind. However, 'chi-toitsu' also denotes a special winning mahjong hand made of seven pairs of tiles. Winning with a chi-toitsu guarantees a good score!
