You start with four fundamental elements — Air, Fire, Water, and Earth — and a blocked-off research map.
Each study presents a small hexagonal board with two or three fixed elements. Your goal is to connect them with an uninterrupted chain: elements connect if one is part of the other or if they are both part of the same entity. Place incorrect neighbors together and nothing will happen; find the right path and a golden thread will appear between them.
The board provides a limited supply of resources, enough for the intended path and a bit extra. Use them wisely; run out and you'll need to clear a node and retrieve the element.
Completing each study unlocks a new element, opens up further studies that require it, and adds a page to the Library, where each element stores its recipe and known connections.
There are twenty-two studies, twenty-six elements, no time limit, and no risk of failure.
How to play
Exploration tree. Tap on a research disk to open it. Move the tree by clicking and dragging anywhere on it; use the mouse wheel to zoom in or out. If a disk is marked with a question mark, it means the research is locked — complete the required tasks to unlock it.
Puzzle grid. Take an element from the «Aspects at Hand» tray and place it on an empty node. You can also move elements already on the grid to other empty nodes without using up any resources. Click on an element to remove it from the grid and return it to your tray. Sealed elements are part of the puzzle and cannot be moved or removed.
Hover over an element to see its name and recipe. The counter on each tile shows how many of that element you have left. The «Watch an ad» button gives you an additional element of your choice as a bonus, which isn't necessary to solve the puzzle.
Top bar. Use «Tree» and «Library» to switch between screens, the selector to change the language, and the sound button to mute or unmute.
