Every box is drawn on its own with these odds, from published seeds: they never change, and any box can be checked.

How each box is drawn

  1. The listSeries 01, version 3: the Xeeds whose art is ready, each with a share by its rarity, 62 in all.
  2. The seedsA demo seed, published below, and a seed made for your visit when the page opens.
  3. The boxHMAC-SHA-256 of the two seeds and the box’s number gives a 256-bit number; its remainder by 62 falls in one form’s share.
  4. The checkEach passport keeps its receipt. The page recomputes a box on request, and anyone with the same seeds gets the same box.

In this demo the seed is public, so a box can be worked out before it is opened. A paid edition would publish only the seed’s SHA-256 first, and the seed after.

How it works

  1. ChoosePick an open series beside the box.
  2. Take100 Eco Credits buy one sealed box.
  3. ShakeIf you like: swing the box with the pointer, press it or use the arrow keys; on a phone, switch Motion on and shake the phone. It tells nothing about what is inside.
  4. PeelDrag the seal off the box, or press Peel the seal.
  5. LiftDraw the lid up until it lets go, or press Lift the lid.
  6. TurnThe card comes out face down. Tap it, drag it sideways or press Turn the card over.
  7. MeetOne individual, its rarity and the first page of its passport. They stay until you press Continue.

Why each form has its rarity

Aurelia, Black-eyed Susan Core
Not assessed by the IUCN Red List; secure across North America (NatureServe G5).
Calix, Purple pitcher plant Uncommon
Secure overall (NatureServe G5), but its trade is controlled under CITES Appendix II, and one mountain variety is Endangered.
Filix, Boston fern Core
Least Concern on the IUCN Red List. Plants in trade are grown by tissue culture.
Velora, Pink lady’s slipper Uncommon
Least Concern on the IUCN Red List, but its trade is controlled under CITES Appendix II, and it is still dug from the wild for sale.
Flabellum, Ginkgo Very rare
Endangered in the wild on the IUCN Red List (1998); first-class protected in China. Planted in streets worldwide.
Red maple, Red maple Core
Least Concern on the IUCN Red List.
Racema, Hyacinth Core
Not assessed by the IUCN Red List, and no threat to the wild plant was found. Garden bulbs are cultivated stock.

What a box includes

Cost
100 Eco Credits a box. The demo gives you a wallet of 500, enough for 5 boxes; it refills when you start the demo again or leave the page.
Eco Credits
Points for caring for a Xeed, such as watering on time and keeping it in range (Proposed). They cannot be bought, sold or cashed out, and they are not carbon offsets.
One box
One individual. No reroll: a box once opened stays opened.
Rarity
A form is as rare as its paired species is endangered in the wild: Core, Uncommon, Rare, Very rare or Rarest, from the IUCN Red List and CITES. Rarity does not change how the plant lives.
Odds
Each form has a share by its rarity: Core 12, Uncommon 6, Very rare 2. A box’s odds are its form’s share out of all 62, the same for every box and every visitor.
Draw
Every box is drawn on its own from published seeds. Nothing about earlier boxes changes the odds, and nothing is given for a full set.
Series 01
16 Xeeds: 7 open now, and 9 species that join as their art is done. Each time one joins, a new version of the list and its odds is published before a box of it is opened.
Duplicates
The same form can come out again. Each seed is a different individual.
Shaking
Every box holds the same seed capsule and card, so a shake sounds and feels the same whatever form is inside. It cannot tell you the form.
Sound and motion
Both are off until you switch them on. The sound is made in the page and placed around you, best with headphones. Motion is for phones: the readings stay in this page and are neither kept nor sent.
Included
The individual, its seed and the first page of its passport. This demo grows nothing.
Payment
None. A paid edition would be for adults only, with the odds and total cost shown first.
