The game, developed in partnership with web development agency Sense Internet, requires players to follow a sequence of coloured mobile phone screens bleeping and lighting up. It gradually gets harder as various visual and sound distortions – simulating some real types of deafblindness – are introduced.
The game, called "Sense-less", aims to raise awareness of deafblindness and to encourage people to donate their old mobile phones to Sense. The charity receives up to £100 for each phone recycled.
The game will be online for eight weeks from today. Players will also have the chance to win a new mobile phone with accessibility software.
Sense's corporate partnerships fundraiser, Nick Connolly, said: "This is the first time we've done anything like this and it would not have been possible without the expertise of Sense Internet. We hope the game will help us raise vital funds, as well as going some way to helping the public understand more about what it could be like to be both deaf and blind."
Aidan Cook, managing director of Sense Internet said: "We saw particular synergy in helping Sense utilise our online gaming expertise."
