Another Casual Strategy Game - Double Star

It's not Gomoku, but if you like turn-based, strategy games, try the space adventure game:  Double Star II. 

As starship captain, your first task is to stop the alien invasion. After that, you search the stars for the alien home world so you can destroy them and end the threat once and for all.

Fast-paced, space adventure



Turn-based does not mean slow-paced. Battles go quickly.

Try it: Double Star II on Google Play.
