Hey, gang :) I got the idea for this game from another website, but I made the powerpoint from scratch (drum roll, please). It's similar to battleship where you can split your students into groups. Every student starts with 10 points each and have to guess where the five treasures are hidden. But you there are booby traps and level ups hidden in the grid too. The team with the most treasures/who finds all five treasures wins the game :~)

PS: This was made with basic Powerpoint skills. So please feel free to customise the game and make it your own :~D
