Because there's Untei there! Challenge to go around the earth! For some reason, it is an endless one-touch action that is just moving around the earth around 35 degrees north latitude. Untei is a bar that is insecting, and people who walk on it will step on it, so let's avoid it by making full use of two-bar and one-bar swapping. The goal is to circle the earth, but the game will continue until you make a mistake after achieving it, so how many times can you go around the earth? Let's challenge! A super popular work that won the No. 1 out of about 2000 games in the action game genre popularity ranking of NTT DoCoMo "i-mode".
