## Sunome Variations

The main challenge of a Sunome puzzle is drawing a maze. Numbers surrounding the outside of the maze border give an indication of how the maze is to be constructed. To solve the puzzle you must draw all the walls where they belong and then draw a path from the Start square to the End square.

The walls of the maze are to be drawn on the dotted lines inside the border. A single wall exists either between 2 nodes or a node and the border. The numbers on the top and left of the border tell you how many walls exist on the corresponding lines inside the grid. The numbers on the right and bottom of the border tell you how many walls exist in the corresponding rows and columns. In addition, the following must be true:

• Each puzzle has a unique solution.
• ﻿﻿There is only 1 maze path to the End square.
• ﻿﻿Every Node must have a wall touching it.
• Walls must trace back to a border.
• If the Start and End squares are adjacent to each other, a wall must separate them.
• Start squares may be open on all sides, while End squares must be closed on 3 sides.
• You cannot completely close off any region of the grid.

In addition, these variations of Sunome have the following extra features:

• Paths (borders with a hole in the middle) designate places where the solution should pass through.
• Pits (black squares) designate places where the solution does not pass through.
• Portals (circled letters) designate places where the solution should pass through and teleport from one portal to the other.
• Sunome Cubed is solved similarly but on the surface of a cube. The numbers on the top right, top left, and center left of the border tell you how many walls exist on the corresponding pairs of lines inside the grid. The numbers on the center right, bottom right, and bottom left of the border tell you how many walls exist in the corresponding pairs of rows/columns.

Examine the first example, then solve the other three puzzles.

The solutions are shown below.

## The Four Oaks

A father left to his four sons this square field, with the instruction that they divide it into four pieces, each of the same shape and size, so that each piece of land contained one of the trees. How did they manage it?

The solution is shown below.

## Out of Time

In the position below, Black played a move, but right before he pressed the clock, he ran out of time. However, the judge declared a draw instead of awarding a victory to the opponent. Why?

The rules of FIDE state that if a player runs out of time, their opponent wins the game IF they have a path to victory. If there is no sufficient material, e.g. a King and a Knight against a King, then the game is declared a draw.

In this position, Black played Rxg6 which forces the moves:

1. … Rxg6+
2. Nxg6+ Rxg6+
3. Kxg6+ Qxg6+
4. Kxg6

This leaves White with a King and a Knight against Black’s King. Thus, White did not have a path to victory and the game was declared a draw.

## Everything and Nothing

Turn me on my side and I am everything. Cut me in half and I am nothing. What am I?

The answer is THE DIGIT 8.

If you turn it on its side, you will get the symbol infinity. If you cut it in half horizontally, you will get the number 0.

## Get One Hundred

9 8 7 6 5 4 3 2 1 = 1 0 0

Add +, +, +, – anywhere above in order to get a valid equality.

9 8-7 6+5 4+3+2 1 = 1 0 0
