Ah!  I have the new version, and it does indeed entertain
me, and appear to be correct.  While we're here, I'll make
a couple of comments:
A.  I'd likely replace
        col[z]=c[col[z]%5]
    with
	col[z] = c[col[z] % len(c)]
B.  You can replace
        col = []
	for z in range(w*h):
	    col.append(z)
    with
	col = range(w * h)
C.  I think what you're *really* after, though,
    is
	    # Make copies of the color list to
	    # fill out the whole grid, then
	col = (c * (1 + t / len(c)))[:t]
	    # shuffle the colors.
	random.shuffle(col)
D.  Similarly, there are ways to recode maker()
    so that it's briefer, easier to understand,
    and less tricky in its global manipulation.
E.  There are choices for c, w, and h that leave
    the "board" unplayable--that is, all pairs
    have been matched, and all that's left are
    unpaired colors.

Nice work!
