Oinky Tonk vs Rich Pirates
Oinky Tonk
Oinky Tonk is a casual game where you get to spin a wheel to decide whether you can attack another player, build your island, or plunder others' islands for money to fund the construction/decoration efforts for your island. There are, naturally, many islands that you will be able to progress to and eventually own.However, you can, in turn, be attacked (destroying some of the stuff you've built) and plundered (lose your cache of cash) as well so it would be wise to have shields on at all times. You can perform retaliatory attacks, thankfully, but this only works if your enemy doesn't have a shield on, obviously.
Generally, this game's gameplay is pretty similar to Pirate Kings and many other casual "Spin the Wheel"-type games, including its adorable graphics and fancy animation effects, and hence, Oinky Tonk would serve as a great alternative game to play.
Rich Pirates
Rich Pirates is a really simplistic game where you just need to pull the lever, spin the slot reels, and see what you get! You can get a chance to attack other players and plunder their bounty, defend your own pirate island, or even spend your ill-gotten gains on ship improvements and aesthetics that will make other pirate captains weep in jealousy. It may not be an exact "spin the wheel"-type of game, but it's very similar to Pirate Kings.So, if you love playing Pirate Kings, you'll want to play this game. It's fun, easy to get into, and competitive!
