User interface

This page describes the in-game user interface (or in-game UI for short). The UI allows the player to choose between placing boxes, crosses, or other marks that can help solve the nonogram. It also allows use of weapons (only available to guild participants), customization of the nonogram colors and toolbar, and much more. You will encounter this UI every time you want to solve a nonogram, so getting familiar with it is essential.

## Number bars

Number bars (sometimes also called "clues") are ambiguous instructions for how to solve a nonogram. They are ambiguous, because the player must figure out through logic how to color each cell. Number bars are comprised of one vertical bar and one horizontal bar. The vertical bar gives the clues for how cells should be colored vertically, and the horizontal bar gives the clues for how cells should be colored horizontally.

Number bars have 3 extra settings, which are mainly used for easier solving of 20x20 or bigger nonograms. Touch and drag on parts of the number bars to use these features:

* **Number bar** - scroll the number bar between clues.
* **Black arrow with yellow overlay** - move the number bar closer or farther from the nonogram grid.
* **Black triangle with blue overlay** - increase or decrease the size of numbers/cells on the number bars.

## Toolbar

The toolbar consist of 10 main buttons, most of which can be can be customized. Below are explanations of buttons, menus and sub-menus.

Default buttons

Color button has 2 options:

* Option 1:  All-in-one button - cycle between color-cross-empty every time you tap on a cell.
* Option 2:  Color button (default) - color or clear the cell on tap.

## Marks

Marks are used for marking cells. Marked cells are not counted as boxes or crosses, but more like empty cells. They are usually used for easier counting of cells or marking, which cells could be boxes. Below are listed all the possible marks:

* mark A
* mark B
* mark C
* exclamation mark
* question mark
* zen mark
* dot mark (default)
* slash mark
* arrow marks - if you drag them across cells, they change the arrow mark to the arrow mark dragged in that direction

There is also a little menu that shows when a certain mark is selected. When marks are drawn the player can then select one of these options in the menu to change the marks drawn into the selected option (box, cross or empty cell). These menus are faded, when no marks are on the nonogram grid.

## Tools

Tools are meant to help the player solve nonograms faster, easier and improve your solving experience as a whole.

 **Straight line**: drag to color cells in a straight line. The direction of the line can be changed, while drawing it by moving your finger closer to the wanted direction. This tool can't draw diagonal lines.

 **Arbitrary line**: drag to color any cell your finger touches. Can draw diagonal lines 2 cells wide and even 1 cell wide, if you are careful enough. Can't draw arrow marks diagonally (only in one direction).

 **Rectangle**: drag from one corner of the desired area to the opposite corner to color cells in a shape of a rectangle.

 **Paint bucket**: tap on a box, square, cross or mark to color the entire section. It colors every cell that is touching (not diagonal touching) the box, square, cross or mark you have tapped. Behaves very oddly when paired with arrow marks.

 **Color picker**: tap on a box, square, cross or mark to select a color, empty square, cross or a mark; then it switches to the line tool or free hand tool - depends on what you have used the latest. Can be also tapped and dragged; then it switches to the line tool and after releasing switches back to the color picker. Can also be tapped on number bars.

 **Ruler**: hold on a box, cross, mark, cell or clue to measure the length of the selected line. Drag to measure the length of the selected line. Detailed explanation:

* When tapping and holding on a box, cross, cell or mark - measures the height and the width of the selected box, cross, cell or mark (must be a continues line and longer than 3 cells).
* When tapping and holding on a clue (in number bars) - measures and calculates the length of the entire line with crosses.
* When dragging a box, cross, cell or mark - measures the length of the selected line (it doesn't matter if it's a box, square, cross or mark).
* When dragging on clues - measures and calculates the length of the selected clues with crosses.

There is also an option to lock or unlock already drawn boxes/crosses. If it's unlocked (left image), the player can freely draw over/overwrite boxes and cross. If it's locked (right image), some special rules apply:

* If boxes are selected, you can't draw over/overwrite crosses, unless you start from a cross.
* If cross are selected, you can't draw over/overwrite boxes, unless you start from a box.
* If marks are selected, you can't draw over/overwrite either boxes or crosses.
* If empty cell is selected, you can still draw over/overwrite boxes or crosses.
