Fill and Flow | Neumorphic Puzzle HTML5 Game

Fill and Flow is a relaxing, brain-friendly HTML5 puzzle game with a soft, tactile neumorphic look. Guide a colourful blob along connected paths, fill every cell of the grid, and watch each puzzle come together in a calm, satisfying flow. Built in pure HTML5, CSS3 and JavaScript, it is lightweight, fast to load and ready to add to a game portal, website or web app.

How the Game Works

Each stage presents a grid of dots and pathways. Your task is to guide the blob through the routes so that the whole grid is filled, without retracing a path in a way that blocks the solution. As you progress, board sizes grow and the challenges become more intricate, while the friendly visuals and gentle pacing keep the game accessible for casual players of all ages.

Key Features

• Infinite procedural levels: a Self-Avoiding Walk (SAW) algorithm generates endless, 100% solvable puzzle grids with scaling board sizes.
• Soft neumorphic design: 3D-embossed, tactile interface elements that feel modern, clean and inviting.
• Light and Dark modes: switch themes to suit your mood, with adaptive colour palettes that change across stages.
• Custom synth sounds: procedural sound effects created with the Web Audio API, with no need for external MP3 or WAV files.
• Unlockable jelly faces: earn stars by completing puzzles and spend them in the built-in shop on cute jelly faces and avatar skins.
• Mobile-first and responsive: smooth play on desktop, tablet and smartphone, with layouts that adapt to different screen sizes.
• Lightweight and dependency-free: pure HTML5, CSS3 and JavaScript for fast loading and easy integration into portals and websites.
• Easy to customise: adjust colour palettes, sound effects and the look of the blob to create your own version of the game.
• Single-file delivery: supplied as one fully commented HTML file, fill_flow_game.html, so setup is simply uploading the file and opening it in a browser.
