Above you find the simplest variant of a ten-by-ten
'three-square cover-uncover sliding puzzle'.
(Note that by using a link on this page outside the game board and its
buttons you will leave the puzzle and go to a different page.)
But even in this trial version you will need no fewer than 24 moves to
solve the puzzle!
If and when you can easily manage these eight blocks, you may proceed to
the second, much more complicated variant with
This puzzle belongs to the only type of three-square cover-uncover sliding
puzzle with a central covered square of six by six cells (at least as far
as boards smaller than twenty-one by twenty-one cells are concerned).
The total board of such an interactive puzzle consists of 100 cells.
In the initial arrangement the central covered square is completely covered
by a bigger central covering square of eight by eight tiles split up into
at least 8 different blocks.
In the final arrangement the central square of 36 cells is all that is
left open when the blocks with their 64 tiles are moved to the sides.
Once the central six-by-six square is uncovered, you will see the lyrics
Liu Cheng Liu or
the Six By Six in Zhezhong
It is a children's song sung in Tale Six of
Six Warlocks My Age.
In this short story, entitled "Numerically Superior", the senary system
(with base six) is vigorously, and not entirely unconvincingly, defended by
a community of warlocks (m/f) against those who attempt to impose a denary
system (with base ten) on them.
Like the society portrayed in that story this puzzle, too, seems to hover
between six and ten.
