The original activity’s name is “Treasure Hunting.” The transition source, input, and indications of whether it is an initial status are described on the front of a pictogram, and the transition target is described on the back. Figure 1 on the left shows an example of finite state automaton, and Figure 1 on the right shows the same structure as the state is constructed by several human pictograms. The player turns over a pictogram with a status number written on the chest. The next status is then illustrated on the back of the selected pictogram. The player attempts to catch the target pictogram (Number 5 circled in the Figure 1(right))
