One Line Drawing is a drawing logic-puzzle game that currently features six chapters of drawing challenges that contain dozens of levels per chapter. Once the player starts a chapter, their goals are to successfully complete increasingly difficult challenges and unlock new levels.
The titles of the chapters are Save the Tralala, Draw One Part, Match Emoji, One Line, Draw Bridge, and Draw to Save. The player can choose a chapter in any order. Over time, they receive access to new chapters.
With the current options at the time of this writing, the player's tasks vary widely. With Save the Tralala and Draw to Save, for example, they must draw barriers, bridges, walls and other objects to protect characters from threats. For Draw One Part, they must draw a shape missing from a partially completed picture as accurately as possible.
One Line requires the player to complete a picture by drawing one uninterrupted line. Draw Bridge tasks them with designing different types of bridges to help vehicles reach flags. In Match Emoji, they draw lines between matching icons in pairs based on a category, an emotion and other common relationships.
One Line Drawing rewards the player with coins. They earn extra money by viewing advertisements. With their coin balance or ads, they can request hints. They can also use video views to skip levels.
