An ad after every word entered as well as after every round, whether you choose to watch for bonus or not. Also ads across the bottom of the screen. Just another worthless game thrown together quickly by greedy lazy people. Absolute bare minimum effort in developing a game, then fill it full of ads to try and force people to spend money. I'll admit, it's not a completely ridiculous amount of money like most apps, but $3 is still too much. There's not enough to it to justify spending that much.
