Abstract
We consider rotational beta expansions in dimensions 1, 2 and 4 and view them as expansions on real numbers, complex numbers, and quaternions, respectively. We give sufficient conditions on the parameters so that particular cylinder sets arising from the expansions are winning or losing Schmidt -game.
