The Adventure Game. The vortex would claim contestants if they stepped in the wrong place. Although officially the 80's children born in the 70s loved this. This was pre Crystal Maze, Pre-Fort Boyard etc.
Beebot Olympics! I had 5 different activities set up in which pupils had to direct the Beebots around obstacles, such as: zig-zagging through cones; finding their way around a maze; rolling a die onto a large 100 square and directing it to the number it landed on. This was with a Year 3 class.
