You need to create a game that is going to challenge the other class with their knowledge of spreadsheets.
On December 11th the other Year 7 class will play the game that you have created.
In a linear game you need to solve each problem in order.
So some problems will not be solvable until the previous problems are solved.
The problems can be solved in any order, but you may have elements like 'Caught in the Code' where one problem can't be solved until another is complete.
Be about Spreadsheets
Have at least five puzzles to open five padlocks
Have a storyline
Be able to complete in 40 minutes
