CELL TYPES

Fifteen different cell types are provideed by Magnum Opus:-
  • Active Cell: As in any crossword system there is of course the active cell into which a letter of the solution will be entered.

  • Pattern Cell: Also there is the standard black pattern cell.

  • Null Cell: This is similar to the black pattern cell, but has the added feature that it will not be printed when the puzzle is sent to the printer, or solved on the computer.

  • Bar Cells: There is a floor bar, a wall bar and a corner bar. These are similar to the standard pattern cell in that they terminate a word, but they also allow a letter to be inserted into the cell.

  • Tunnel Cells: These are pattern cells which do not contain a letter, but they also do not terminate a word. The word continues on the other side of the tunnel. There are horizontal and vertical tunnels which do not change the direction of a word, and there are four right angle turn cells which change the direction of a word by 90 degrees.

  • Direction Cells: There are three of these, and they are similar to the normal pattern cells, but they also contain arrow symbols indicating a direction. One has a left pointing arrow, one has an upward pointing arrow, and the third contains both left pointing and upward pointing arrows. When a puzzle is being built by Magnum Opus, the words which are pointed to by these arrows will be inserted into the puzzle in the Reverse direction. You can use this function in any way you wish, but mainly it is intended for puzzles which are destined to be printed in the ArrowWord format.
