The Crack the Safe games are designed to engage children in an exciting way to help recap on prior learning by breaking the codes to unlock the safes. Children look for the correct answers and write down the corresponding code, creating a 5-digit answer. They can then input this into the safe to unlock whatever rewards you wish to give your class. You can review the questions and answers at the end of each safe or 'lock' it if they have too many failed attempts.

NB: ALL versions of the game have the SAME codes for the corresponding safe. For example, Bank 1 for the Romans has the same code as Bank 1 for the Egyptians. Each Bank has a unique code within the game itself, so Bank 1 and Bank 2 have different codes, but it would take an incredible amount of time to change all of the codes for each individual Bank in each individual version of the game.
