Interactive Apps
A teaching twist on chess: every move must be unlocked by a times-table (sifir) question. Choose a move, answer the multiplication prompt correctly, and the piece advances — turning ordinary play into rapid mental-arithmetic drill. Built as an installable Progressive Web App that runs fully offline, with same-device two-player mode and an optional online room for cross-device matches.
