One game for example move by move:

Start position. - the board is empty. -all pieces are in hands:

3 2 1 white Wr.gif (126 bytes) Wb.gif (112 bytes) 99.gif (1529 bytes)
00.gif (844 bytes) a
33.gif (844 bytes) b
c
      black Br.gif (128 bytes) Bb.gif (114 bytes) Bk.gif (97 bytes)

1. K*2c
Black starts the game and drops his King. (There was 8 squares to choose):

3 2 1 white Wr.gif (126 bytes) Wb.gif (112 bytes)
a
b
c
      black Br.gif (128 bytes) Bb.gif (114 bytes)

2. K*2a
White drops his King. There was 3 squares to choose
and White got symmetrical position:

3 2 1 white Wr.gif (126 bytes) Wb.gif (112 bytes)
a
b
c
      black Br.gif (128 bytes) Bb.gif (114 bytes)

3. R*1b
Black drops his Rook. There is possible to choose value of piece when dropping,
but here Black tries strong grip to middle square and 1st column with Rook:

3 2 1 white Wr.gif (126 bytes) Wb.gif (112 bytes)
a
00.gif (844 bytes) Br.gif (128 bytes) b
c
      black Bb.gif (114 bytes)

4. SW*3b
White drops his orthogonal-cube as Swallow's Wings.
The idea was to protect middlesquare and think the promotions,
next times GB would be strong value with checking...:

3 2 1 white Wb.gif (112 bytes)  
00.gif (844 bytes) a
Wsw.gif (925 bytes) Br.gif (128 bytes) b
c
      black Bb.gif (114 bytes)

5. CS*1c
Black drops his diagonal-cube as Cat's Sword.
The think was natural, to add the pressure to middlesquare,
and again, the idea for CS is to move CS next to middle
and checking with promoted Dog:

3 2 1 white Wb.gif (112 bytes)  
00.gif (844 bytes) a
Wsw.gif (925 bytes) Br.gif (128 bytes) b
00.gif (844 bytes) Bcs.gif (936 bytes) c
      black

6. B*3a
White drop his Bishop. Now the board is close, all the pressure is directed on middle.
It's typical that player who is obliged to start from these positions,
can easy lose a material:

3 2 1 white
Wb.gif (112 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Br.gif (128 bytes) b
00.gif (844 bytes) Bk.gif (97 bytes) Bcs.gif (936 bytes) c
      black

7. K-3c
Black discovers intersting move. If White captures B's Rook,
then Black can capture W's Swallow's Wings:

3 2 1 white
Wb.gif (112 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Br.gif (128 bytes) b
Bk.gif (97 bytes) 00.gif (844 bytes) Bcs.gif (936 bytes) c
      black  

8. Bx1c=TG
...but White's King didn't want the Rook,
he captures with Bishop and promoted to Tile General.
Cat's Sword is now White's piece in hand:

3 2 1 white Wcs.gif (938 bytes)
00.gif (844 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Br.gif (128 bytes) b
Bk.gif (97 bytes) 00.gif (844 bytes) Wtg.gif (111 bytes) c
      black  

9. Rx1c=C
Black's natural capturing equalized the material
and he gets control for 1st column:

3 2 1 white Wcs.gif (938 bytes)
00.gif (844 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) 00.gif (844 bytes) Bc.gif (914 bytes) c
      black Btg.gif (912 bytes)

10. B*3a
White drops CS as Bishop to the same square as before,
and threatens B's Chariot in 1a:

3 2 1 white    
Wb.gif (112 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) 00.gif (844 bytes) Bc.gif (914 bytes) c
      black Btg.gif (912 bytes)

11. K-2c
Black moves his King to protect his Chariot.
Notice, that Black cant protect his C by dropping TG*1b,
because it's illegal to check with drops.
Other possibility was to move C-1b=SW, if W's Kx1b then
White can capture W's SW:

3 2 1 white    
Wb.gif (112 bytes) Wk.gif (100 bytes) a
Wsw.gif (925 bytes) 00.gif (844 bytes) b
00.gif (844 bytes) Bk.gif (97 bytes) Bc.gif (914 bytes) c
      black Btg.gif (912 bytes)

12. B-2b=TG
White moves to the centre and threatens again B's Chariot:

3 2 1 white  
00.gif (844 bytes) Wk.gif (100 bytes) a
Wsw.gif (925 bytes) Wtg.gif (111 bytes) 00.gif (844 bytes) b
00.gif (844 bytes) Bk.gif (97 bytes) Bc.gif (914 bytes) c
      black Btg.gif (912 bytes)

13. C-1b=SW
Black moves ahead his Chariot and securites his piece
and with new value he also threatens now W's TG:

3 2 1 white  
00.gif (844 bytes) Wk.gif (100 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Wtg.gif (111 bytes) Bsw.gif (923 bytes) b
00.gif (844 bytes) Bk.gif (97 bytes) 00.gif (844 bytes) c
      black Btg.gif (912 bytes)

14. K-3a
Just the King move was reasonable and White choosed the left corner.
An idea of left side corner is also interesting, if B would like to capture
right Kx3b, which leads interesting position of Kings.

3 2 1 white
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Wtg.gif (111 bytes) Bsw.gif (923 bytes) b
00.gif (844 bytes) Bk.gif (97 bytes) c
      black Btg.gif (912 bytes)

15. SWx2b=GB
Black captures ....

3 2 1 white
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
Wsw.gif (925 bytes) Bgb.gif (924 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) c
      black Btg.gif (912 bytes) Btg.gif (912 bytes)

16. SWx2b=GB+
...and White hits back by capturing with Swallow's Wings and checking.
Both players have still same amount,
but Black has two diagonal-cubes in hand:

3 2 1 white Wgb.gif (134 bytes)
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
00.gif (844 bytes) Wgb.gif (134 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) c
      black Btg.gif (912 bytes) Btg.gif (912 bytes)

17. K-3c
W's King gives way to the left corner...

3 2 1 white Wgb.gif (134 bytes)
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
00.gif (844 bytes) Wgb.gif (134 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) c
      black Btg.gif (912 bytes) Btg.gif (912 bytes)

18. R*1c
White drops to the opposite corner and makes real threat to White,
because next GB-2c=R would mean checkmate:

3 2 1 white  
Wk.gif (100 bytes) 00.gif (844 bytes) a
Wgb.gif (134 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) Wr.gif (126 bytes) c
      black Btg.gif (912 bytes) Btg.gif (912 bytes)

19. CS*3b
Black's only possibilities was to drop Bishop or Cat's Sword to 3b:

3 2 1 white  
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
Bcs.gif (936 bytes) Wgb.gif (134 bytes) 00.gif (844 bytes) b
Bk.gif (97 bytes) Wr.gif (126 bytes) c
      black Btg.gif (912 bytes)  

20. R-1b=C
White defuses the pressure in 2c,
but at the same time takes the 1st column by Chariot:

3 2 1 white  
Wk.gif (100 bytes) 00.gif (844 bytes) 00.gif (844 bytes) a
Bcs.gif (936 bytes) Wgb.gif (134 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) c
      black Btg.gif (912 bytes)  

21. D*2c
Black drops his diagonal-cube as Dog.
Not bad idea, if White retreats with Go-Between to 2a...

3 2 1 white  
Wk.gif (100 bytes) 00.gif (844 bytes) a
Bcs.gif (936 bytes) Wgb.gif (134 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Bd.gif (900 bytes) c
      black  

22. GBx2c=R+
...but White captures the Dog and checking:

3 2 1 white Wd.gif (902 bytes)
Wk.gif (100 bytes) 00.gif (844 bytes) a
Bcs.gif (936 bytes) 33.gif (844 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Wr.gif (126 bytes) c
      black  

23. CSx2c=D
...and White captures with Cat's Sword.
The position seems easy without any danger, but...

3 2 1 white Wd.gif (902 bytes)
Wk.gif (100 bytes) a
33.gif (844 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Bd.gif (900 bytes) c
      black Br.gif (128 bytes)  

24. CS*2a
White finds great chance! Again, it doesn't seem danger,
but look at this carefully: -what White can do after this dropping!
-King can't move, but also his Dog can't, bacause it's value will
change to B and checkmate, but unfortunately it's illegal, because
Black has still one piece in hand. -So, only possibility is to drop
piece from hand, but good alternatives are not dense:

3 2 1 white
Wk.gif (100 bytes) Wcs.gif (938 bytes) a
00.gif (844 bytes) 33.gif (844 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Bd.gif (900 bytes) c
      black Br.gif (128 bytes)  

25. R*1c
Black tries his last hope, if White's Chariot will capture the Rook...

3 2 1 white
Wk.gif (100 bytes) Wcs.gif (938 bytes) a
00.gif (844 bytes) 33.gif (844 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Bd.gif (900 bytes) Br.gif (128 bytes) c
      black

26. CS-2b=D
...but White has realized the position and he makes right away checkmate.

3 2 1 white  
Wk.gif (100 bytes) 00.gif (844 bytes) a
Wd.gif (902 bytes) 33.gif (844 bytes) Wc.gif (916 bytes) b
Bk.gif (97 bytes) Bd.gif (900 bytes) Br.gif (128 bytes) c
      black

This test game wasn't top-level, not at all, because there is easy to find better moves for each players, but any way, the game shows a pretty good the charachter of nana shogi.
I wish that this example will creats your interest to play this World's Smallest Shogi Variant.
Of course it's possible, that this game lost playable after deep analysis and research, but still it will give many interesting moments and variety for new and experienced shogi players, as my fafourite Micro (popii) Shogi has shown.

Tämä esimerkkipeli ei ole tasoltaan mikään huippupeli, sillä molemmille pelaajille löytyisi tehokkaampia siirtoja, mutta  se kuitenkin osoittaa hyvin pelin luonteen.
Toivon, että tämä esimerkki herätti mielenkiintonne kokeilla tämän maailman pienimmän shogi muunnoksen pelaamista.
Tietysti on mahdollista, että peli menettää pelattavuutensa, jos sitä tutkitaan syvällisesti, mutta uskon, että ennen sitä se tulee antamaan kokeilijoilleen nautittavia ongelmatehtäviä myös edistyksellisemmille shogin pelaajille, kuten suosikkimuunnelmani Micro shogi on osoittanut.
