A lot of the features don't work reliably. For instance, some bears are able to "summon" word endings like "ED", "ER", etc. but even when you have more than adequate space for the letters to appears, sometimes only one of them will pop up. There's no way to guess which orientation they'll drop in, so you often end up wasting them. But you still have to upgrade those bears because not having the right "type" will keep you out of earning for special events.
I already have the paid version, and I can tell this is all meant to squeeze more out of me. It just won't work. Eventually when it gets frustrating enough, I'll just stop playing.
