Work together to find what two times tables have in common.
Hint gives a strategy. Show answer appears after checking and records a shown pair rather than a solved pair. Clear board erases this pair's work and retracts its result, keeping your settings.
Beyond 100 asks for the first common multiple greater than 100. No overlap on this board does not mean no common multiples exist.
Settings lets you draw cards or choose a pair from 2–12, including equal numbers. Start game resets progress after confirmation when needed. Use Tab to reach the grid, arrow keys to move, Home/End for the row ends and Enter/Space to mark. Share this setup opens a fresh unsolved game. Fullscreen enlarges the display. Print prints the current display on one A4 landscape side. Home returns to Interactive Tools.
