Lava speaking game. Students must guide the teacher from one spot on a map to another, avoiding the lava. I played this as a group game. One group continued giving directions until they ran into lava and then the next group got a chance.
Also, pirate ship directions game I made for my summer camp. Almost the same concept. Students give directions to guide their ship from one spot on a map to the treasure, avoiding sea monsters, waves, rocks, etc.
