Very hard to get more than a bronze trophy

Ive played many, many games and I cant seem to ever win more than a bronze trophy, and thats even after Ive found 30+ words and spelled them correctly. Wish they enabled silver and gold a bit faster - its frustrating not fun :( Note: game will immediately unfreeze by clicking "x" on top right above "install".
