Finding a hazard is simple. Once you think you've seen a hazard simply hover your mouse over it, if the Dorset and Wiltshire logo appears you've found the hazard. If you don't see the logo and you're sure you've found a hazard, try moving your mouse slightly and see if it appears, if you're really stuck you can click on "Get a hint". Once you click on the logo, you'll hear some information about the hazard, you'll need to wait until the explanation has finished before looking for more. You can track the number of rooms and hazards remaining in the box at the top right of the screen, once you've found all hazards in a room you'll see a button appear prompting you to go to the next room, complete all the rooms to access your certificate.
People with hearing impairments can view a text transcript of the audio by clicking the assistance icon in the box at the top right corner of the screen. If the icon is red transcriptions will not be shown, if it is green transcriptions will be shown. Transcriptions will remain visible for the duration of the audio clip being played.
When you've completed a room, the system will recognise this. If you subsequently leave the game and return a short time later you will resume from the start of the next room.
