Are you looking for other games like Tribal Wars for iOS and Android? While there are plenty of online strategy games in this genre it's harder to find good quality games that you can play on your smartphone. Of all the alternatives I've tried a few of stuck with me and I'm making this page to share these options with you.
My requirements for games to be featured here were simple, it had to have enough players in the community that the game was active enough to enjoy (a strategy game with only 100 other people doesn't create much gameplay) and it had to be available on either iOS or Android devices (preferably both). Some of these games do feature connected game worlds while others are separated depending on the device.
Please note that because these games are played over an internet connection that they will use your phone data when not connected to WiFi, don't get caught out!
