Although addicting and fun, the game will get boring after a while due to the lack of things to do.
The small strategy I mentioned is due to the clock. It ticks down to your doom. If you string together same shaped bubbles, you get more points. If you constantly burst bubbles, you will get a small time boost. The key is to constantly balance the two out. That balance of score-striving and time conservation is the only real trick to mastering Pop. Though are more difficulties, it pretty much stays the same. Also, even with a few power-up bubbles thrown in for diversity, the repetitive action makes Pop tedious once you get the hang of the balancing act.
The multiplayer mode is similar, but it adds a bit of frustration to the players. Some things like the thunder bolt will anger opponents. It is one of many annoying bubbles one can pop. It can make a cursor useless.
It will be somewhat satifying(at least to me) to see friends get angry at it. This mode doesn't really focus on a high score more than angering friends.
It is a very simple and easy game to play. Maybe to easy and simple. The low level of strategy and easiness really lessens the experience. Although additive, the hameplay gets old after a while with not much to master. With not much to do the game really isn't worth the 700 Wi Points.
