Choose Play classic for a standard brew, or Play challenge to use the rule shown in the opening story.

Drop dew, sparks and pebbles into a bubbling cauldron. Merge matching materials into bigger ones and keep the brew below the rim for two minutes.
Each merge scores the material it makes: Spark 2, Pebble 6, Leaf 12, Mushroom 20, Crystal 30, Moon 42, Sun 56, Star 72 and the Philosopher’s Stone 90. Two Philosopher’s Stones that touch vanish together for 110 points. Dropping scores nothing; only merges do. These are in-game points, not real money.
A challenge locks one of three reviewed brew rules before the brew starts. When AI responds, it writes the opening story and selects the rule. A local challenge uses the same list when AI is unavailable, rotating by UTC day. Physics, merging, the drop sequence and scoring still follow the local game rules.
The displayed rule locks when you start. Classic mode needs no AI response, and a late response cannot change a run already in progress. If AI is unavailable, a clearly labeled local challenge keeps the game playable.
At the end, the result shows stars, score, whether the brew lasted two minutes or overflowed, your largest material, drops, longest merge chain and any actual Crystal Week bonus points. An optional reflection uses those recorded totals. If the reflection service is unavailable, the result uses a labeled local reflection.
AI can select one of three reviewed brews with a matching opening story: Crystal Week doubles points for merges that make Crystal or anything larger, Gentle Brew lets materials sit above the rim for four seconds instead of two, and Double Preview shows the next two materials. Physics, merging and scoring stay on your device, and the drop sequence is the same for everyone each UTC day. At the end, compare your score, largest material and any actual challenge bonus, with an AI or clearly labeled local reflection. Local challenges and Classic remain free options when AI is unavailable.
