- Garden: tap a bed to plant (Mint is free), tap again to water. Tap a ripe bed to harvest it into your seed bag.
- Board: only herbs in your seed bag sprout here. Swipe to match 3; matches fill your pantry.
- Brew: chop and grind herbs in quick mini-games, put 3 jars in the pot and stir a figure-8. Wrong mixes make sludge, but the Book keeps hints.
- Shop: sell potions for gold (or drink them for power-ups). Gold buys tools; notes from experiments buy research. The coach shows you the rest.
