Fat Dragon is a free puzzle game developed by Tuna Bowl Software LLC. that offers a unique and engaging gameplay experience. The objective of the game is to help the dragon get fatter by eating all of the desserts while avoiding spikes and holes. To do this, you must draw a path for the dragon to follow. However, obstacles and desserts disappear when you enter draw mode, so you must use ground references and your short-term memory to draw the best path.

The game offers two modes: Arcade and Survival. In Arcade mode, you aim to get a 3 cupcake rating for each level. In Survival mode, you try to achieve a high score by eating as many desserts as possible while avoiding obstacles. The game is easy to learn but challenging to master, with increasingly difficult levels that will keep you entertained for hours.
