Figure 2. Screen Shot of Dig Rush.
High-contrast red elements (miners and fireball) are seen by the amblyopic eye. Low-contrast blue elements (gold and cart) are seen by the fellow eye. Gray elements (rocks and ground) are seen by both eyes. Both eyes must see the game for successful play. Dig Rush was developed in collaboration with Robert Hess, PhD, DSc, at McGill University (Montréal, Québec, Canada), and Amblyotech (Atlanta, Georgia) and UbiSoft (Montréal).
