ArcLight Inc. (Headquarters: Chiyoda-ku, Tokyo) announces that its conversation-focused cooperative board game 'ito' has surpassed a cumulative total of 1 million units sold worldwide. The fourth installment of the series is scheduled for release in 2027. About 'ito' 'ito' Players: 2-10, Playtime: 30 minutes, Recommended Age: 8+ In this game, all players cooperate to arrange cards numbered 1 to 100 in sequential order. Players are forbidden from speaking the numbers on their cards. Instead, they communicate using 'prompts' to convey their numbers and try to guess each other's numbers. As a cooperative game, players can aim for victory in a friendly atmosphere, and even if they fail, they can enjoy discussions about their differing values. It's recommended for all situations, whether discovering a friend's surprising side or breaking the ice with someone new. In recent years, its high communication-inducing power has led to its widespread use in educational and welfare settings. 'ito Rainbow' allows for team play, and 'ito Classic' features a classical design. ▼Introductory video explaining how to play in 1 minute 'ito' Series Development Since its release in August 2019, the 'ito' series has been supported by many users as a 'communication game that shares values that cannot be conveyed by words alone.' In addition to the expansion of series products, ArcLight has realized various initiatives beyond the scope of board games, including book adaptations, collaborative products, and amusement prizes. In 2023, a major step was taken towards overseas expansion, and the game is now available in 11 languages worldwide. In May 2026, the cumulative sales of the 'ito' series worldwide surpassed 1 million units. 'ito' will continue to challenge new possibilities as a communication game that connects people across generations and borders.
