How to play Mineralium
Enjoy Lines 98, Color Lines and matching coloured balls? In Mineralium, you form lines of minerals, collect essence and descend into a mine. Start with five minerals of the same colour.
Your board: the essenciator
Form lines on a 9 × 9 board and make room for new minerals. Cleared minerals fill the flasks with essence of their colour.
Keep going and descend as far as you can. When the board fills up, your descent ends.

Make a move. Match five
- Select a mineral, then an empty cell.
- Check the path: minerals move through free cells horizontally and vertically. The path can turn and go around other minerals.
- Form an unbroken horizontal, vertical or diagonal line of five or more minerals of the same colour.
The line disappears, freeing cells and adding essence to the matching flask. In the diagrams, a gold outline marks the moving mineral and a dashed outline marks its destination.

A single straight line holds up to nine minerals. If a move completes several lines, you can clear more than nine at once. A mineral at an intersection disappears only once.

Look one move ahead
If you do not complete a line, new minerals appear — usually three.
Turn on the lantern to see their colours and future cells. Small preview minerals show what comes next; large minerals are already on the board.

More depth, more colours
You begin with five mineral types. Three more are gradually introduced as you descend, bringing the palette to eight types.

A joker matches the colour you need
The rainbow geode is a joker mineral. It stands in for the colour needed to complete a line.
Move it into the empty cell between four red minerals to form a line of five.

One joker, two lines
Here the joker connects four red and four blue minerals. Nine minerals disappear, including the joker, and essence of both colours flows into the matching flasks.
Nine is the result in this example, not the limit for one move.

Go deeper. Keep your finds
Your score shows the depth of your descent. Along the way, chests hold finds, including artifacts that unlock new possibilities. Read each acquired artifact’s card for details.
Full flasks and rewards are kept after your descent ends. Essence in unfinished flasks is not.
