Boom Space vs Pet's Island
Boom Space
Boom Space is a Spin-the-Wheel game that is similar to games like Pirate Kings or more accurately, Piggy Boom. The game features adorable graphics that help it stand out from among the other games within the same genre, and not to mention, unlike other games that will have you building up islands, this game lets you build planets instead. However, the gameplay is still pretty much the same as what you'd expect from such a game - you'll essentially be spinning a wheel in hopes of getting an action - to attack a player's planet or to shield your own - or a freebie, be it free spins or coins.Like Shark Boom and Piggy Boom, you can collect pets in this game but unlike the latter, your pets can't defend your island. They are simply there for show.
So, in many ways, I'd say Boom Space is more like Shark Boom in terms of its graphics and features than Piggy Boom, Greedy Gods or Pirate Kings. However, the gameplay for all these games are basically the same, so if you enjoy playing one of these games, you'll enjoy playing the others.
Pet's Island
Pet's Island is a casual PvP/ island-building game that's very similar to games like Coin Master and Pirate Kings where all you need to do is to press a button to spin the wheel. The wheel will then decide on which action you can take, be it attacking another fellow player's island or stealing their gold.There are also tons of differently themed islands for you to build and collect. This game is very social as well since it encourages you to add as many friends as you can, just so you can get a lot more spins. However, unlike other games in this genre, Pet's Island require you to focus on developing your pets, much like in Pokemon, just so they could help you defend your island from unwanted invaders.
So, if you enjoy those "spin the wheel"-type games, you migth want to check this game out. The characters in this game are absolutely adorable and the gameplay is familiar yet innovative enough to keep you engaged for hours on end.
