MARBLE ALCHEMY FIELD GUIDE

A browser roguelite where the AI writes today’s question.

Play without a download or account. GLM-5.3 Flash writes a bounded daily challenge; Matter physics executes it locally, so the AI has a visible role without taking control of every collision.

Play the AI DirectorCompare both builds

1. What changes each day?

The model chooses one of three bounded mechanics: double the first hit, restore one life after a winning settlement, or begin as a glass cannon with two lives. The validator rejects invented mechanics before the challenge reaches the browser.

2. How to play a run

  1. Aim with mouse, touch or arrow keys, then launch.
  2. Let every marble settle. Damage is released after the volley, so a dense collision path matters.
  3. After a victory, choose one of three upgrades: power, fire, lightning, split, critical or heal.
  4. Finish five escalating stages. The result screen combines the model-authored guidance with your measured shots, damage and remaining life.

3. What is measured?

The site records anonymous product events such as page views, starts, AI challenge loads, rule triggers, completions, restarts and shares. Browser progress stays local. No name, email, payment data, file content or model key is collected.

4. Why compare the baseline?

The fable 5.1 build keeps the same five-stage marble structure without the AI Director. Comparing it with the AI build helps separate the value of model-authored challenge design from the value of the underlying physics and upgrade loop.
