The example puzzle seems to have a second solution, different to the one published.

if 'O's are islands and '%' are streams:

OO%%%%%%%O
%%%OO%OO%O
%O%OOO%%%%
%O%%O%OO%O
%%O%O%O%OO
O%O%%%%O%%
O%%OO%OO%O
%%OO%%%%%O
%O%%%OO%OO

also seems to be a solution.

Black squares must connect in a single stream. Your 5th row 8th column has an isolated %, an isolated "pond" of water which prohibited by the rules. Alsee 15:10, 23 March 2007 (UTC)

Yep, the stream squares are not exactly "streams"; they should form a single stream. Wipe 02:09, 23 June 2007 (UTC)

[edit] What is a binary determination puzzle?

I was suprised to see "binary determination puzzle" did not have its own wiki article, despite appearing on many of the puzzle pages. Is this accepted terminology? What, exactly, does it mean? Quaternion (talk) 04:53, 6 December 2007 (UTC)

I suspect that "binary" refers here to the fact that every square has two possible states. I concur that the opening paragraph is not very good as of now. Wipe (talk) 23:54, 28 February 2008 (UTC)
