# Glossary

## Advanced mode

An arbitrary cutting of a puzzle. Single pieces can have a lot of various shapes. The puzzle can include holes and the shape of the puzzle does not have to be only rectangular. To create such a puzzle is slightly more difficult but it is worth it.

## Context Menu

A menu pertained a concrete object (e.g. album, puzzle, selection and so on). You can elicit this menu by moving the cursor on a certain object and clicking the right mouse button.

## Minimal size of a piece

The smallest size of a piece is defined by the monitor resolution. It is impossible to play with pieces sized 1 x 1 pixel, therefore the minimal size of a piece in the program is limited to 10 x 10 pixels. The Create Room will not allow you to make smaller pieces.

There are more monitor resolutions (800 x 600, 1024 x 768, 1280 x 768 ...) and if a friend sends you a puzzle and his/her monitor resolution is higher than yours, while entering the Play Room a following situation may arise: the puzzle scales down suitably for your resolution, together with the puzzle also every piece scales down and if the size of such a piece drops under the minimal size, the number of pieces will change. In this (rare) case the number of pieces displayed in the icon representing a puzzle do not correspond with the number of pieces displayed and played in the Store Room.

## Number of pieces

The number of pieces a puzzle is composed from. The number of pieces displayed in the icon representing a puzzle may not agree with the number of pieces displayed and played in the Store Room in scarce cases. See Minimal size of a piece.

## OpenGL

OpenGL (Open Graphics Library) is a standard specification defining a cross-language cross-platform API (Application Programming Interface) for writing applications that produce 3D computer graphics.

## Room main menu

It is a small panel with buttons, which can be found in every room. It contains the most important commands for the entire room. The last button is "Back", which sends you to the previous room, or "Exit", which closes the entire program.

## Standard mode

A regular network of lines, which are bulged by every piece a little bit. The whole puzzle can have only a rectangular shape and cannot include holes.

If you cannot play a certain movie puzzle, see FAQ.

## Surprise

It is an attribute of a puzzle. A player cannot see the puzzle picture before solving the whole puzzle. That is why such a puzzle cannot be printed, modified, you cannot see its view in the Store Room and you cannot use the "Ghost" or "Image" option in the Play Room. After solving the puzzle loses this attribute. This attribute can be added in the Create Room, Modify Room or when sending the puzzle.
