Maths Escape Rooms
Three narrative rooms where the maths is the action, not a toll gate: no question boxes, just instruments you have to set correctly — a dial, a slider, a keypad. Three locks a room, fifteen minutes each, built to end a lesson rather than fill one. Every room has a teacher page with the answers, the hint ladder and the misconception each lock is built around.
15 minutes a room

New for 2026/27
Updated games have had real work done for this year — new help and worked explanations where there were none, and shorter rounds you can stop after. New games arrived late last year, so most classes never saw them. Every game now feeds the leaderboards and keeps a score history on your device. Everything below also appears in its usual level section.
