Workshop upgrades, research and card bonuses
You build a tower and defend it against waves of enemies. Coins go into the workshop for permanent upgrades, so progress carries over between runs.
Research unlocks new parts of the game and keeps running whether the game is idle or you are playing actively. A card collection adds bonuses to the tower. Live tournaments against other players are the route to unlocking the ultimate weapons. The game also includes new areas and bosses.
Android 8.1 requirement and cost
The Tower needs Android 8.1 or newer. It is free to download, but it contains ads and in-app purchases, which matters for a game built around upgrade progression.
It sits in the games category with simulation tags, in the same area as titles like Royal Kingdom and Gardenscapes.
