Tips
Maintain Balance Across Structures
One of the most important things you need to understand in City Island 5 is that you need to keep a positive, if not perfect, balance across the population number, the available jobs for the people, and the level of happiness the city in general has. Building residential structures increase the population; commercial establishments provide jobs to people and generate profits for the city as well; and community structures, as well as decorations, provide happiness to the citizens.
Check The Benefits Before You Upgrade Or Build
Most especially when your city has flourished enough to contain varieties of structures, deciding how to progress further becomes an important decision as far as impact of upgrades or constructions are concerned. As you can upgrade each structure up to level 10, there will be a lot of instances when doing so will be more cost-effective than actually building more structures. As such, you should always check to see the benefits of both before choosing whether you should consider upgrading an existing structure or constructing a new one.
im To Accomplish Quests And Achievements
City Island 5 most certainly provides you sufficient ways to fund the growth and development of your cities. Keeping an active role in tending to your island’s needs, as well as of its inhabitants, always ensure that you will earn something to help you keep moving forward in your adventure. On top of the profits you get from your commercial structures level ups, you can earn cash, gold, keys and other rewards by finishing quests and reaching achievements.

User comments
This game is crafted with great care; if you’re willing to take your time, you don’t need to spend any money at all—it’s a truly fair, player-friendly experience. The weather changes are also quite charming! It would be great if you could add a "collect all" button for earnings, as well as a way to categorize items based on the type of terrain they can be placed on—that would make gameplay much more convenient! Thanks!
I quite like this game. However, it would be even better if I could collect all the keys or plane tickets with a single tap. I assume there’s a reason for having to collect them manually—perhaps to encourage players to check back into the game and grow their funds—but having to tap 1,300 or 1,900 times (to collect 13 silver keys or 19 plane tickets across 100 banks) is a bit frustrating.
I stumbled upon this game by chance, and it’s definitely a five-star experience. Also, check out this site [ad-guy-penis-chopping-site]—you get a free knife upon signing up that lets you chop off the "ad guy's" junk! It’s completely free-to-play; don't you want to give it a try? It’s so much fun—a really, really great site. If you’ve got some spare time, come check it out! It’s a blast—everyone should come and play!

Summarize
City Island 5 is a challenging city-building game that's strongly inspired by games such as 'Cities Skylines' or the pioneer 'Sim City'. The game is perfectly adapted to smartphones and even adds clicker-like management elements.
