Patent number: 8979656Abstract: A game system includes multiple game machines which implement a game by alternating turns. Each game machine implements the game on its turn, and transmits game progress information to the other game machines. The game is implemented in accordance with the transmitted game progress information. A host game machine of the game machines transmits turn determination information to the other game machines, and receives turn completion information from each of the other game machines. When the turn confirmation information is not returned from one of the other game machines, the host game machine recognizes that communication has been cut off. When the communication has been cut off, the host game machine functions as a substitute for the cut off game machine.Type: GrantFiled: May 8, 2007Date of Patent: March 17, 2015Assignee: Kabushiki Kaisha Square EnixInventors: Masanori Ichikawa, Toshiyuki Uehara, Akihito Ota, Kei Shimo, Toshihiko Machita, Kunihiro Sasagawa

Publication number: 20070281791Abstract: To continue, in a communication game system configured of three or more terminal devices, a game with remaining terminal devices when a communication of a portion of the terminal devices has been cut off, without preparing a surplus terminal device. Four game machines implement a game by alternating one turn each. Each game machine, on its own turn, as well as implementing the game on the relevant turn based on an input thereof, transmits game progress information based on the relevant input, and turn determination information indicating a determination of the relevant turn, to other game machines. The game is implemented in accordance with the game progress information and turn determination information received from the other game machines.Type: ApplicationFiled: May 8, 2007Publication date: December 6, 2007Applicant: KABUSHIKI KAISHA SQUARE ENIX (also trading as SQUARE ENIX Co., LTD.)Inventors: Masanori ICHIKAWA, Toshiyuki UEHARA, Akihito OTA, Kei SHIMO, Toshihiko MACHITA, Kunihiro SASAGAWA
