Background

Sketchbook, developed by Swift 502, belongs to the drawing-based physics puzzle genre, where players sketch shapes and lines directly onto the level to solve each challenge, similar in spirit to games like Happy Glass but framed around a hand-drawn sketchbook aesthetic rather than a specific liquid-filling premise. That art style gives the puzzles a charming, informal feel, as though solutions are being scribbled directly onto a notebook page.

Open-ended drawing puzzles like this tend to have more than one valid solution per level, rewarding players who experiment with different sketched shapes rather than searching for a single "correct" answer.

How to Play

• Mouse — draw lines and shapes directly onto the level to solve each puzzle.
• Use your drawn creations to interact with the level's physics and objectives.
• Experiment with different sketched solutions for each puzzle.
• Complete levels by successfully solving their drawing-based challenge.

Goal & Purpose

The objective in each level is to sketch a solution that satisfies that level's specific physics-based objective, with creative drawing rewarded over any single fixed answer.

Why Play Sketchbook

Its charming hand-drawn style and creative puzzle-solving make for a relaxing, satisfying challenge. GBK Games also has Happy Glass for another drawing-based physics puzzle.
