Stackopolis is surprisingly simple to play, all you have to do is to just click on the blocks to move them into the target for each of the 20 unique levels. A 3-dimensional view is provided as well as a top-down blueprint that identifies the number of each block that is required for each cell of the play field grid. To add some tension and a bit of challenge to the game, a timer counts down the seconds you have to complete each level. If you fail to meet the target within the time limit the game ends. This game features elegantly simple gameplay, gorgeous pixel graphics and animations, and a delightfully dramatic soundtrack that pushes this game over the top into highly addictive territory.
