What kind of game this is

Save The Kingdom: Merge Towers is a tower defense game that uses a tower merging mechanic. The listing places it in the Casual category and describes it as free to play. The developer is Unimob Global, and the game is rated Everyone 10+.

The goal, as the summary puts it, is to merge towers and defeat all the enemies. Defense is built around combining what you already have, not just placing new towers on the map.

Building, upgrading and merging towers

You build towers, upgrade them, and merge two towers together to make a more powerful one. The result is a stronger defense without starting over with new placements.

The developer says this mechanic is meant to push players toward planning ahead and making choices about which towers to combine.

Tower levels and their abilities

The listing gives more than 20 tower levels to merge. Each tower has its own abilities and strengths, so the mix you build can change how you handle a given enemy.

Because towers differ, the listing says you can tailor a defense to the enemy types and challenges you face, instead of using one setup for every stage.
