Grow the World Tree. Burn it down. Grow it back stronger.

What Grows Here

🌱

One number: sap

Five tablets feed the tree: Roots, Trunk, Branches, Canopy and Fruit. Every 25 levels a tablet doubles its output, so steady buying turns into fast growth.

🌡

Seasons that keep real time

A 20-minute year runs on the clock, even while you are away. Spring cuts prices, Summer doubles sap, Autumn drops fruit to catch, and Winter slows growth to a third.

🔥

Ragnarök is the point

Burn the tree down when it is tall enough. You keep the seeds, and every seed makes each new tree grow 12% faster, forever.

⚡

Three gods, three ways to play

Pick a pact at every burn. Odin rewards being away, with up to 24 hours of offline growth. Thor rewards being present with Mjölnir strikes. Loki gambles in Autumn.

ᛉ

Runes, realms and relics

Carve the 24 runes of the Elder Futhark into the trunk, light the stones of nine realms, and send expeditions home with relics. Some tablets stay locked until you do.

🐉

Something gnaws at the roots

Every tenth Ragnarök, Nidhogg comes hungry. What happens next is up to you.

How to Play

1

Grow

Tap the tablets to spend sap on Roots, then Trunk and Branches. The tree grows, and so does the sap it makes each second.

2

Read the season

Buy in Spring while prices are low, let Summer work, catch Autumn’s fruit, and wait out Winter or skip it.

3

Burn it down

When Ragnarök is ready, burn the tree for seeds and choose the god who will watch over the next one.

4

Grow back stronger

The new tree starts from a seed, with every seed you have ever earned behind it. Each run goes further than the last.

Plays one-handed in portrait. The tree keeps growing while the app is closed, and Android has a home-screen widget.
