With 48 cards divided into four suits of 12 cards we make the FOZUDOKU of THREE Magic Squares.
With the same deck we can also do:
- a FOZUDOKU of FOUR Magic Crosses
- a FOZUDOKU of FOUR Magic Stars (6-pointed)
There are only 80 6-pointed Magic Stars with and not all of them can be used and fit into a FOZUDOKU, which in addition to having the constant sum (26) requires that none of the four cards (XXXX) that add up to the same, have a repeated suit.
ALL the Magic Crosses have the numbers (5, 6, 7, 8) in the 2 × 2 square in the center, so there are also not many Magic Crosses that can be made.
Neither the Magic Crosses nor the Magic Stars are comparable to the 4 × 4 Magic Squares of the classic FOZUDOKUS, with which thousands of different FOZUDOKUS can be created. In any case, although the Crosses and the Magic Stars have these limitations, I have thought that they are relevant, as they are also made with the Spanish deck, which gives them added value, as no suit is repeated in any of the 4-card groups (XXXX) that have the constant sum (26), and it is for all this that I have added them to this blog, as something curious and anecdotal, which deserves to be disclosed among FOZUDOKUS lovers.
FOZUDOKU of 4 Magic Crosses
FOZUDOKU of 4 Magic Crosses with four visible cards on each CROSS.
The 4 visible cards, which serve as a clue to solve and complete the FOZUDOKU, in ALL CROSSES are:
- 3 cards of different suits forming an oblique line
- 1 card located anywhere on the CROSS, EXCEPT on the line parallel to the line that has 3 visible cards
(the line parallel to the oblique line that has 3 cards, NEVER has a visible card)
The eight cards that remain to be placed are calculated taking into account the 15 groups of 4 cards (XXXX) that add up to 26 and no suit is repeated.
How to solve the FOZUDOKU of 4 Magic Crosses
The FOZUDOKU of 4 Magic Crosses, can be created following the following THREE STEPS:
- 1- Select cards
- 2 – Placing cards
- 3 – Discovering 4 cards
1 – Select cards
To select the cards we divide each suit into 4 groups of THREE cards.
The numerical sequence of these groups of THREE cards of the same suit are
( 1, 5, 9 ) ( 2, 6, 10 ) ( 3, 7, 11 ) ( 4, 8, 12 )
For each CROSS, we select 12 cards divided into four different suit groups.
First Step – Select the 12 cards of the Magic Crosses
2 – Placing cards
To place the cards, we will first visualize the CROSS in two parts:
The central part – (four cards in the 2×2 square in the centre)
The off-center part – (eight cards NOT in the centre)
Before we place the selected cards in groups of three we choose the direction we will follow when placing the cards: (clockwise) or (counter-clockwise)
We place the cards alternating the part of the cross (centre and outside the centre), jumping from one part to another following the movement of the chess knight.
FIRST GROUP: (ONE – The first card is placed off centre), then (knight jump to centre – TWO – The second card is placed in the centre), then (knight jump off centre – THREE – The third card is placed off centre).
SECOND GROUP: (ONE – Place the first card out of the centre, next to the last card placed from the First Group), then (knight skip to centre – TWO – Place second card in centre), then (knight skip out of centre – THREE – Place third card out of centre).
THIRD GROUP: (ONE – Place the first card out of the centre, next to the last card placed from the Second Group), then (jump horse to centre – TWO – Place second card in centre), then (jump horse out of centre – THREE – Place third card out of centre).
FOURTH GROUP: (ONE – Place first card out of centre, next to the last card placed from the Third Group), then (jump horse to centre – TWO – Place second card in centre), then (jump horse out of centre – THREE – Place third card out of centre).
(cards placed in the centre are always the second card from each group)
When we finish placing all the cards, we already have 4 Magic Crosses with the cards face down.
Step 2 – Place the cards face down at the Magic Crosses
3 – Discovering 4 cards
In each Magic Cross we will discover 4 cards that will serve as a clue to solve the FOZUDOKU.
These cards are:
- 3 cards in one of the 4 oblique lines that each CROSS has
- 1 card anywhere but on the oblique line parallel to the line where we have placed the 3 cards.
Third Step – Discover 4 cards at the Magic Crosses
FOZUDOKU of 4 Magic Stars
The Star of David has six points and is made up of two triangles:
In this FOZUDOKU we use 4 Stars of David to place 12 cards on each of them (6 cards at the points of the star and 6 cards at the points where the two triangles that form the star intersect):
In the FOZUDOKU of 4 Magic Stars, each of the Stars has 6 visible cards and there are 6 cards left to place.
These 6 cards are placed taking into account the NINE Groups of four cards (XXXX) that add up to the same (26) and have the four suits of the deck:
- SIX Groups of 4 cards (XXXX), Groups 1, 2, 3, 4, 5, 6, are on the sides of the two triangles that form the star, which have four cards of different suits and add up to 26
- THREE Groups of 4 cards (XXXX), Groups 7, 8, 9, are formed by the card of one of the points, the card of the opposite point, and the two cards in the middle, it also adds 26 and a suit is not repeated.
NINE Groups of 4 cards (XXXX) that have the constant sum (26) and have the four suits of the deck.
