I play word also and am having the same troubles. I close the Words app completely when it won't load, from the home screen do the four finger swipe up or double press the home button to reveal your multi task bar. These are all the apps that you have opened at one time. Long press the app until it jiggles and a red minus sign will appear above it. Press the minus sign, this will close the app, not delete it. It's the only step we have until the Developer fixes the problem.
