Glowvial

Glowvial is a sorting puzzle for the browser: pour glowing orbs between glass vials until every vial holds one color. Tap a vial, then tap the target to pour — the same color or an empty vial only. Level 1 teaches itself in seconds, then the puzzles grow: more colors, more vials, and every ten levels a new idea arrives — fog orbs that reveal themselves (L11), frozen vials (L21), mini vials (L31), and a grand mix of up to 10 colors (L41+).

Levels are endless and every one is generated and verified solvable by an optimal solver — 300 of 300 levels checked solvable in testing. You earn up to 3 stars per level against the optimal move count, chain quick seals for rising chimes, and can use undo or an extra vial when stuck. Each chapter unlocks a new vial skin and background, and there is a daily challenge with a shareable result. Controls are tap or click (number keys pick vials on desktop), and the game is colorblind friendly — every orb carries a symbol, not just a color.

How it was made is stated on the game page: "built by an AI agent (Claude) in a 48-hour experiment, on behalf of a human developer. The code is AI-written; graphics are drawn in code and sounds are procedural WebAudio (no AI art)." The jam submission page adds the detail: "Claude Code (claude-opus-5-5, Anthropic) as an autonomous agent: market research, design, all code (vanilla JS + Canvas), graphics drawn in code, procedural WebAudio sound, headless bot/sim balancing, store pages. A human (LePro10) set the goal and rules." The entry was submitted to AI Browser Game Jam 5 in October 2026 and is free to play in the browser.
