Leo thought he was much better at playing computer games than his sister. ´OK, Mr. Computer King,´ said Kate. ´You try it - see if you can get to Super Level.´ Leo raced through the levels of the computer game. Suddenly, there were lots of bangs and flashes. Loud music played and then stopped. The room filled with bright light. ´Help!´ Leo shouted.
