Be Smart

This game is fun. I can play for hours and days without dropping a dollar. Be patient and the game will pay its own way. It does cost some but not nearly as much as other similar games. Try it you’ll like it.

Mr. PPD ,


I gave this game 3 stars. Graphics is nice. Overall composition is interesting and addictive. It has certain level of challenge. Unfortunately, the game has several drawbacks.

1) It requires at least primitive help document.
a) Yellow dollars are - ... and can be used for ...
b) Green dollars are - ... and can be used for ...
c) Stars can be used for only ...
d) Port can become profitable and can be enabled only when ...

I actually still don't know answers on all these questions.

It's absolutely imperative to be able to know how to:

2) Hide all game icons from the window perimeter. They are really annoying!
3) Convert dollars in gold and back. At a certain point, dollars are accumulated in huge amount of millions, being absolutely useless.
4) Understand that houses, land, commercials, unlock, etc. change their prices right in front of your face.

But the biggest problem is that

5) The game drains the battery 2-3 times faster than during a normal computer use. And I have a brand new 15" MacBook Pro (End of 2017)

6) Because you can't shut the game off, when buildings are under constructions, you run it non-stop for days. After a day of playing your computer resources are totally dedicated to the game only and all other Apps are significantly slowed down and start behaving wired.

I understand that the game is free (it still requires some at least gold purchase to keep it running), but adjustments are really necessary to be able to enjoy it in full.

Graphics neat, but here are my suggestions….

Enjoy playing this game. Graphics are pretty neat. Would like to see the navigation icons be a tad smaller, I’m always clicking them when trying to click a building. Also, being able to manuever to all the properties better would be nice. Especially those along the edge of the screen. Even in full screen, I have to position the beach area on the right side of the screen around the navigation icons, just to view them or to collect from the commercial buildings. Boats in the channels are huge!! Love the detail, but honestly, they should probably be a little smaller for the channels. Maybe the bridges should raise some? to allow boats to travel beneath instead of disappear at each one? Also, why not have a small town grocer or mercantile or feed store a church at the beginning in the lower cost ranges? Kind of odd that you go from farming to bam, pizza and steak houses. lol
