The following guide is for the basic rules. Sometimes the rules are applied simultaneously with another rule which may change the color or symbol on the tile.

Reactive tiles turn orange when clicked.

Stable tiles are informational. May be clicked for more information but are not reactive or unreactive.

Cluster Tiles – Indicated by 7 orange hexagons on the level selector

Orange reactive tiles with a number and a chain link symbol. The number represents the number of reactive tiles adjacent to one another. All tiles around it will be unreactive.

Line Tiles – Indicated by a red line with arrows at the ends on the level selector

Red stable tiles with a number and an arrow that, when clicked on, show a line between it and its partner. The number represents how many reactive tiles are between the two partners.

Area Tiles- Indicated by a blue hexagon with arrows pointing outward on the level selector

Blue stable tiles with a large number and a smaller superscripted number. The large number indicates the number of reactive tiles in its area and the smaller number is how far the area extends in all directions. To easily see the area, click on the blue stable tile.

Min Chain – Indicated by a green chain inside of angle brackets -- >< -- on the level selector

White tiles with the equal-to-or-greater-than symbol with a black number and a chain link symbol. The number represents the minimum number of adjacent reactive tiles there can be. All adjacent tiles must be at least that number or more but must have at least one chain equal to that number. Tiles that are adjacent to the chain but not adjacent to the white tile, do not affect the chains length.

Max Chain – Indicated by a yellow chain inside of angle brackets -- <> -- on the level selector

White tiles with the equal-to-or-less-than symbol with a black number and a chain link symbol. The number represents the maximum number of adjacent reactive tiles there can be. All adjacent tiles must be at least that number or less but must have at least one chain equal to that number. Tiles that are adjacent to the chain but not adjacent to the white tile, do not affect the chains length.

Groups - Indicated by a turquoise chain link inside of squiggly brackets (braces) on the level selector

Red stable line tiles with a number inside braces: { } . The number indicates the number of groups of linked tiles there can be between it and its partner. The groups can be of any length.

Note: There are also white group tiles with numbers inside braces. The number represents the number of groups directly adjacent to that tile. The groups can be of any length.

Not! – Indicated by a purple exclamation point on the level selector

White tiles with an exclamation point followed by a number indicates the number of reactive tiles that cannot be adjacent.
