In this podcast, David Woodbridge gives us a demonstration of ChangeReaction, Draconis Entertainment's classic audio puzzle game which is now available on OS X with new audio, three entirely different modes of game play and a host of other new features.
Primarily intended for blind and visually impaired gamers, ChangeReaction is played via the keyboard and your ears. Navigate the game board with the arrow keys, dropping coins on the stacks to create chains of explosions and rack up higher and higher scores. Match three coins of the same denomination vertically or horizontally to trigger a chain reaction that blows up all adjacent coins of the same value.
This game has no visual element. Use your fingers, ears, and wits to rack up the highest scores possible!
