Originally born in the tangled confines of the fabled labyrinth of the Spaghetti Code, the Big Ball of Mud known as Muddini has an indomitable desire to free himself from this chaotic web. Muddini is a reference to the "Big Ball Of Mud", which (unfortunately) all programmers have probably encountered at least once in their careers. A Big Ball Of Mud is a program that has no recognizable software architecture and that experienced programmers should avoid Know. One goal while playing is to keep Muddini as small as possible. If Muddini is too big at the end of the maze, he won't fit through the black hole and won't be able to complete the level.

In Muddini’s Adventure you go on an exciting journey through the spaghetti code labyrinth. Muddini is controlled either by touch or with the phone's gyroscope. The little mud ball rolls through the corridors and collects game elements - good or bad, which make it smaller or larger in a detrimental way. Muddini has three lives, which are lost whenever the playing time in the level runs out. If all lives are gone, players have to wait two hours to continue playing.

To avoid the waiting time, daily streaks can be collected. To do this, at least one labyrinth must be completed. A day streak gives you an extra life. A three-way streak provides three extra lives. If at least one maze has been played every day for a week in a row, a D-Bagger will be unlocked, which restores five lives.
