Itsutsu, a quiet board for five-in-a-row descendants
A browser board for gomoku, renju, connect6, and 27 other line-and-grid games, built for two players on separate devices.
Field notes
Itsutsu organizes thirty line-and-grid games into a shared browser board, with rules, remote turns, move-by-move records, and branching rematches. Its remote mode passes the other player a code for play across two phones, while the record system preserves stone order and displays rating movement. The homepage labels the product Beta 0.60.1 and describes it as invitation-only. Its backstory connects the design to the founder's family correspondence games on older turn-based sites.
