This paper presents novel designs for the sonification (auditory representation) of data from grid-based games such as Connect Four, Sudoku and others, motivated by the search for effective auditory representations that are useful for visually-impaired users as well as to support overviews in case that the visual sense is already otherwise allocated. Grid-based games are ideal to develop sonification strategies since they offer the advantage of providing an excellent test environment to evaluate the designs by measuring details of the interaction, learning, performance of the users, etc. We present in detail two new playable sonification-based audio games, and finally discuss how the approaches might generalise to general grid-based interactive exploration, e.g. for spreadsheet data.
