In Doodle Puzzle, each Drawy (artist) creates a complete depiction of the chosen subject on their own set of boards. During this process, Guessy (the guesser) observes the Drawys through a color filter, which hides the pen's lines while revealing only the movements of their hands. This unique rule challenges Guessy’s observation and imagination.

After drawing, each Drawy selects a portion of their artwork, and these pieces are combined into a new, collaborative drawing in the central frame. Baddy (the saboteur) secretly sabotages one or two of these pieces, either by erasing parts or adding misleading elements to obscure the subject.

Once the collaborative drawing is ready, Guessy removes the color filter to view the full artwork and attempts to guess the subject. A correct guess rewards points to both Guessy and the Drawys, while an incorrect guess gives points to Baddy. In the variant rule, Guessy can also try to identify which piece was sabotaged, with additional points at stake.

The game spans five rounds, with roles rotating each time. The player with the highest score at the end wins. Combining creativity, strategic thinking, observation, imagination, and deduction, Doodle Puzzle offers a fresh and engaging challenge in every round.
