Opening your garden…

Where should your tree start growing?

Pick the first unit that feels new. Units before it start as inferred leaves (dashed), and now and then you'll get one question from them to check. Not sure? Start at the beginning.

Colours

Changes the colours only. Everything stays in the same place, and question cards stay on white paper. Surprise me picks a new theme each day.

Special days

On a maths holiday or a great mathematician's birthday, Mathera dresses up for the day and says why. Turn it off to keep your own colours.

Clock

Quick five

For quick calculations in Eras I–III, five small questions appear together and you check them all at once.

Celebrations

When a step is planted or a skill proven, dots gather into a leaf. Big adds confetti and fireworks for bigger moments; Small keeps it short and quiet; Off skips it. If your device asks for less motion, it stays still.

Sounds

Rewards only plays right, wrong and celebration sounds. All adds soft clicks on keys and taps. The speaker button at the top switches sound off and on too.

Stories

A one-line story above some questions. You never need it to answer.

Brave mode

Mixes ★ Brave and ★★ Legend master quests into Continue once you've proven a skill. About half the skills in Era IV have them, and about a quarter in Eras I–III and V. They never wither and never hold you back.

Your Acorn

Your whole tree in one save code. No account and no password: keep a copy somewhere safe, or scan it into Mathera on another device.

Grafting Bench

Grafting adds an Acorn to your tree. It never takes anything away: each skill keeps whichever is further along, yours or the Acorn's.

Tree Rings

Your last 10 versions on this device: one a day, plus one before every graft, reset or step back. Going back to a ring replaces your tree with it (your House Rules and study log stay as they are), and saves today's tree as a ring first, so you can always undo.

Treeprint of any Acorn

A printable Treeprint of any Acorn: the tree, the frontier, memory health and the Acorn's QR code, or the longer Field Guide. It only reads the Acorn and never changes your tree.

Starting unit

Only changes leaves you haven't worked on yet.
