Stacking is an adventure/puzzle video game developed by Double Fine Productions and published by THQ; like Double Fine's previous Costume Quest, it is a smaller title created during the development period of Brütal Legend, and was released in February 2011 for the Xbox Live Arcade and PlayStation Network stores. A Microsoft Windows version has been announced.
The game is based on the Russian stacking matryoshka dolls, an idea coined by Double Fine's art director, Lee Petty, who saw the dolls as a means to replace the standard player interface used in graphical adventure games. The player controls the smallest doll, Charlie Blackmore, who has the ability to stack and unstack into larger dolls and use their abilities to solve puzzles to allow Charlie to free his older siblings and put an end to child labor enforced by the antagonist, the Baron. Puzzles within the game have multiple solutions, and include additional puzzles and challenges that allow the player to explore the game's world outside of the main story.
Your PC will need a graphics card thats as powerful as a GeForce GTX 260/Radeon HD 4870 and it should be paired with either a Athlon 64 X2 Dual Core 4200+/Core 2 Duo E4500 2.2GHz CPU to match the Stacking recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. You should also have 1 GB system memory for min specs. You will require a DirectX 10 GPU. In short you need a 13 year old PC for best Stacking performance.
