a non-slip, easy grip surface. 81 per set.

Original sudoku game pieces numbered one through nine. One of each number per set.

If a candidate within a row or column only appears in one

block, remove that candidate from the remaining squares

in that block.

In the example below, the bottom row has the candidate 5

only in the right block. One of these two squares in the

bottom row must be the 5. Therefore, we will remove

candidate 5 from the top row of the right block.

If two squares in a row, column, or block contain an identical

pair of candidates and only those two candidates, remove those

candidates from the remaining squares in that row, column,

or block.

In this example, the candidates

3 9 in the right column form a

naked pair within the block.

One of the two squares in the right column must be the 3

and the other must be the 9. Therefore, we will remove

candidate 3 from the square in the left column, and remove

candidates 3 9 from the square in the middle column.

Sudoku is a number game that requires no arithmetic - just

logical thinking and the process of elimination. The game is

played on a grid consisting of 9 rows, 9 columns, and 9 blocks.

Each row, column, and block contains 9 squares.

Some of the squares contain numbers, which are the “givens.”

The object is to fill the empty squares so that each row, column,

and block contains all the numbers from 1 to 9. No number

can appear in any row, column, or block more than once.

The **Gold Spike™** wooden game pieces have numbers on both

sides. Use the white numbers for the “givens” and the black

numbers for the ones that you place in the empty squares.

The best way to solve Sudoko is to only put a number in a

square when you are certain it goes there. **Don’t guess!** If

your guess is wrong, you may not discover it until you try

to place the last number on the grid.

By using a few simple techniques, you’ll be ready to start

solving Sudoku. With the **Gold Spike™** Sudoku board game, it's

easy! The first step is known as “scanning.”

in a row or column once. By scanning the rows and columns on

the sudoku board game, it will show where certain numbers cannot

go, and may reveal the one square within a block where a certain

number can go.

You can begin scanning for any number, but it’s better to start

with numbers based on their frequency. Since there are five 8s

in the example above, we’ll start by trying to fill more 8s.

Rows 4 and 5 already have 8s, which leaves one square in the

middle-right block to put the 8.

Columns 2 and 3 already have 8s, which leaves two squares in

the lower-left block. However, there is already an 8 in row 8,

which leaves one square in the lower-left block to put the 8.

Finding numbers will often help find more numbers. Rows 1

and 2 already have 8s, and we placed an 8 in column 8, which

leaves one square in the upper-right block to put the 8.

If you cannot find more numbers to place, thoroughly scan for

every missing number in each block.

While scanning, if you find a row, column, or block that is

missing only a few numbers, it’s a good idea to identify those

missing numbers and see if any of them can be placed.

For example, column 7 is missing 3 6 7. We cannot put the

6 in the bottom square because the lower-right block already

has a 6, and we cannot put the 7 there because row 7 already

has a 7, so the bottom square must be the 3.

The 6 cannot go in the middle square of column 7 because

row 2 already has a 6, so the middle square must be the 7,

which makes the top square the 6.

Remember, finding numbers will often help you find more

numbers, even in blocks that you have already scanned.

At this point, you may want to set up an easy puzzle on your

Scanning will solve most easy puzzles, but when it stops

yielding results, it’s time to begin “marking up.”

for each empty square. To find the potential numbers, which

are known as “candidates”, scan each square’s row, column,

and block for all of its missing numbers.

The **Gold Spike™** Sudoku board game has a unique method of

keeping track of candidate numbers. Pegs are placed in holes to

represent the numbers 1 to 9.

If a peg is placed in the

upper-left hole, it represents

the 1. If a peg is placed in

the lower-right hole, it

represents the 9.

This method of tracking candidates is very easy to learn, and

will help you to recognize patterns of candidate numbers.

Once the candidates are known, we can use solving techniques

to reduce them to a single number in each of the squares.

Here are the basic solving techniques for Sudoku:

If a square has only one candidate,

put that number into the square.

If a candidate appears just once in

a row, column, or block, put that

number into the square. In this

example, 4 is the hidden single

within the block.

If a candidate within a block only appears in one row or

column, remove that candidate from the remaining squares

in that row or column outside of the block.

In the example below, the right block has the candidate 9 only

in its top row. One of these two squares in the right block must

be the 9. Therefore, we will remove candidate 9 from the top

row of the other two blocks shown.

If three squares in a row, column, or block contain only three

different candidates between them, remove those candidates

from the remaining squares in that row, column, or block.

In the example below, a triple is formed by the three squares

in columns 4, 8 and 9 of the row since they only contain the

candidates 1 5 6. Therefore, we will remove candidates 1 6

from columns 1, 3, and 5, which instantly solves the square

in column 5.

It’s important to note that each of the squares which form a

naked triple don’t have to contain all three candidates. In fact,

none of the squares need to have three candidates.

In this example, the candidates

1 3 6 in the left column form a

naked triple within the block.

Therefore, we will remove candidate 1 from the middle

column, and remove candidates 3 6 from the right column,

which instantly solves the square in the right column.

So, the squares which form a naked triple may contain only

two or three candidates each, but what is important is they

contain only three different candidates between them.

Naked triples are rather easy to spot and can often help you

solve a difficult sudoku puzzle.

If four squares in a row, column, or block contain only four

different candidates between them, remove those candidates

from the remaining squares in that row, column, or block.

In the example below, a quad is formed by the four squares in

columns 1, 4, 6, and 9 of the row since they only contain the

candidates 6 7 8 9. Therefore, we will remove candidates 6 8

from column 2, and remove candidates 6 7 from column 7.

Each of the squares which form a naked quad don’t have to

contain all four candidates. In fact, none of the squares need

to have four candidates.

If two squares in a row, column, or block contain an identical

pair of candidates that are not found in any other square in that

row, column, or block, remove any other candidates from

those two squares.

Let’s look at the previous example again. The candidates 2 3

in columns 2 and 7 form a hidden pair within the row.

One of the two squares must be the 2 and the other must be

the 3. Therefore, we will remove candidates 6 8 from the

square in column 2, and remove candidates 6 7 from the

square in column 7.

PRESS RELEASE

Elverson, PA (PRWEB) -- When George and James TerBush learned of the Sudoku puzzle

craze last year, they immediately began drawing up plans for their Gold Spike Sudoku, a

deluxe wooden Sudoku board game they unveiled today. The brothers, who founded the

Elverson Puzzle Company, had to overcome a major obstacle - how do you solve Sudoku

without pencils, paper, and erasing?

If you are not familiar with Sudoku, it is an addictive number puzzle that is played on a 9x9

grid of squares. Each puzzle starts with some squares already filled with numbers. The

object is to fill in the empty squares so that each row, column, and 3x3 block contains all

of the numbers from 1 to 9.

"To solve the more challenging Sudoku puzzles, you need to keep track of the possible

numbers for each empty square," said James. "If we didn't find a way to do that, our Sudoku

board game would not be very useful."

The TerBush brothers devised an innovative method to keep track of the possible numbers.

They created a pattern of nine holes in each square on their Sudoku game board. Gold pegs

are placed in the holes to represent the numbers 1 to 9. The numerical value of each peg is

determined by the hole it is placed into. Upon devising this method, they filed for a patent.

"It has many advantages over other Sudoku board games," said George. "The pegs make it

very easy to add and remove possible numbers from the game board. It also allows you to

add as many pegs as you need. Since there are no numbers on the pegs, the process of

placing them on the game board can be done quickly, and you will never run out of any

numbers. This method also allows patterns of numbers to be easily recognized, which is an

important strategy in solving Sudoku."

The beauty and craftsmanship of Gold Spike Sudoku is a joy to behold. The large Walnut top

game board contrasts nicely with the gold pegs and the numbered wooden game pieces. All

of the contents of this Sudoku board game, including the packaging, are made to the highest

quality. "Our goal was to make it good enough to be on the Antiques Road Show some day,"

said George.

Gold Spike Sudoku includes a 12" square wooden game board, 81 large numbered game

pieces in a drawstring bag, 200 gold tracking pegs inside a game tin, and a comprehensive

instruction booklet featuring 50 Sudoku puzzles by Angus Johnson. Designed for ages 12

and up, the Sudoku board game retails for $34.95. Gold Spike Sudoku is available at

I received my board yesterday. Thank you very much.

I really like the board. I played the first game last night. Your system with the gold

spikes to show the candidates works well. And, I am sure when I am attempting to

solve the more difficult puzzles it will be very helpful! It was an easy transition for

me, since I usually mark the candidates by writing small numbers in the appropriate

9 position spot in the square.

I had looked at other sudoku boards to purchase - but yours had the best design

and quality!

My wife has been playing Sudoku in the paper so I bought the board for her. I

really hadn't played it much. An unexpected bonus is that we now play games

together because we can each participate using the board. It is very well

designed and crafted. It makes a "loner game" into a "group game". The

minute I saw it I knew it was the right one - no other board handles all

9 possibilities as succinctly and clearly as the "gold spike".

I am very pleased with your version of the Sudoku board puzzle. Only thing, I

would prefer the wood number tiles to be a bit heavier and square, but that is

personal preference. Here is my customer testimonial.

I do Sudoku puzzles quite often. For simple to moderately difficult puzzles,

paper is sufficient for me. But for more difficult sudukos, I wanted a table top

board version to work more efficiently with candidates. All of the sudoku board

versions I came across lacked in two areas.... 1) not enough candidate pieces

2) Candidate pieces were to awkward to handle, being small numbered blocks of

wood or plastic that would slow me down. Elverson puzzle solves both problems.

They give you more candidates than you will probably ever use in a sudoku.

They also adopt the pin grid system for the placement and removal of candidates.

I find several advantages to this. First, this allows one to move much faster

while working on a Sudoku. Second, once you get used to the pin grid system

it actually helps you to better visualize locations and values for candidates since

the pins locate the numbers they represent in the same spot of each and every

square. In converting over to this system, I find I make less mistakes. I now

use the same system when going back to pencil marks on paper sudokus. Bravo

Elverson for putting so much thought into the design of this puzzle. This should

be the one on all shelves of the stores.

I recently placed an order for a Gold Spike Sudoku puzzle as a Christmas gift for

my sister and brother-in-law. Almost immediately after placing the online order,

I received an e-mail confirmation along with a FedX tracking number. Today, just

2 business days from placing the order,I received the puzzle at my door. Opening

up the box, the Invoice/Packing Slip even had a handwritten "Thank You" on it.

This is the way America should be doing business. The efficiency, as well as

personal touch, seem to be a long lost art. Thank you to you, your brother, and

all the employees involved for making my day and, to some degree, restoring my

faith! I will certainly recommend Elverson to anyone and everyone. Hope you and

everyone at Elverson have a wonderful (hopefully somewhat restful) holiday

season.

Thanks again.

I should have written much sooner. I want to let you know that the Sudoku

board arrived promptly and in good order. I am so pleased with your good service.

As you no doubt realize more and more board Sudoku games are being advertised.

From what I see, none comes close to the good design and workmanship of the

Elverson puzzle. I congratulate myself on my decision.

Happy holidays and thanks again,

service from your company.

I placed my order for the gold spike sudoku On Monday March 19 and already

received my order on the 22nd. It was such a nice suprise since the estimated

delivery from Fedex wasn't until the 26th. The reason we decided to order this

version is because my Grandad loves sudoku, but has a hard time seeing due

to vision loss. This board is perfect and he will be able to see the pieces more

clearly.
