This game can be carried out as a variation of orienteering competition (map, checkpoints). The tasks are held in checkpoints, which participants must locate first. Once the task is completed the participants receive the coordinates of the new checkpoint. When planning a game, make sure that the teams are sent to different check-points to avoid overcrowding the locations.

Resources needed: a code lock (with 4 numbers) or just a piece of paper for giving answer.

You cannot speak about Internet security without mentioning the topic of strong passwords. But still, a lot of people use weak passwords like “123456”. Nowadays computers are so smart that we can find programmes on the Internet that crack a 9-digit password within a moment.

Our phone SIM cards are protected by a 4-digit password that contains only numbers. This password is often left the same as it was set by mobile operators.

Your mission is to “hack” into the portable safe. Some very important information is hidden inside it. And as we all know, information is one of the most valuable resources nowadays.
