Alpha is the first version of Incredibox that was originally released online as a flash game in 2009.These versions can be played both on the official Incredibox website and on the paid apps.

Each version has a musical style with a unique theme to it. There are eight different versions of Incredibox in the game that the players can choose from. For users who just want to listen to an endless mix, an automatic mode can play loops of each version at random. Then contributors can listen and vote their favorite tracks all the way to the Top 50 chart of Incredibox. To fine-tune a mix, the player can also swap out new sounds, mute sounds, do a solo on one of them, find combos to unlock animated bonuses and record all those interactions to share it on social media via an URL. Each icon is a unique a cappella sound loop to drag-and-drop onto the characters (which represents the musical composer in all versions ) from a range of hats, sunglasses, masks, headphones or other items that dress them as they are used and let them sing in rhythm with each other. These icons are divided into the following categories (five for each of them): beats, effects, melodies and voices. Once one of the available eight versions (or musical styles) has been chosen, the player is provided with an interface made up of seven blank characters and twenty sound icons. Incredibox is a music-making app in which the user can create a mix by managing a group of seven animated beatboxers.
