Once in a while I come across apps that make me go bald in scratching my head, trying to understand the point of them. Coin Master is such an app.
Loosely based on the Viking theme, you will be spending your time staring at the screen, waiting to be able to do something. The goal is to progress from your original Viking village to different settings and locales. You do that by upgrading your current village. For that you need to spend coins. However, coins don't just appear on top of buildings like in most games of this sort. The buildings in this game are completely cosmetic. Coins are made at a slot machine! Yep. Unlike other tappers, where slots can come up as a secondary mechanic, In Coin Master it is the one and only way of gaining a revenue.
The good part is that you don't need three symbols of a kind to receive a reward. Whenever coins or sacks of coins show up, you will gain some. Other results will enable you to steal coins from a random player online. If you connect to your Facebook account and entice some of your friends to join in this pointless endeavor, then you might also get the chance to sack them.
The bad part is that lever pulls are few and far between, You must wait for one hour to get 5 pulls, which can be annoying. That's unless you're willing to spend real money on more.
In a way, Coin Master is the most distilled form of a tapping game. You don't need to wait up for those coins to pop up in your village, just check back hourly for five shots at a slot machine. After that you go back to your village, purchase whatever upgrade you can afford and then tend to your business. Come to think of it, this formula doesn't sound that bad, considering how bloated other freemiums can get these days, Coin Master is a breather.
