Dungleon
As its name suggests, Dungleon plays like an endless dungeon crawler but with words instead of monsters. In each stage, you must navigate through a maze full of traps and obstacles in order to find a treasure chest full of gold coins and gems which will score you points for the next level.
The catch? Word walls block your path when you encounter them, forcing you to use synonyms to bypass them instead: painful> becomes scratch> and mug> becomes drink>. And while each new level is randomly generated by algorithms to keep things fresh and exciting, every time you beat a level there’s always another one waiting just around the corner in case you get too comfortable exploring.
