Here is a free Rubik’s Cube game for you (PC only), You need NOT to install this game, just unzip the downloaded file and execute the exe file, that’s all. It is a portable version. You can save the status of the game and continue when you start it next time by loading the previously saved game.
Below is how you can play the game

only one issue I found is that it will close the window with out any confirmation if you accidently closed it.
Do if you are a Rubik’s Cube fan, download it from Softpedia
