Sherlock Holmes in Chinatown

A renowned clan has taken possession of the seal ring of the Japanese president. Since all important decisions must be sealed with this, the entire country is currently incapacitated. It immediately becomes clear: The seal ring must be returned to Japanese possession as soon as possible! Therefore, on behalf of Sherlock Holmes, it is necessary to infiltrate the clan's premises without being noticed and to closely examine the headquarters. Divide yourselves cleverly, prove yourself in Asian gambling, and find the seal ring!
