According to Austrian puzzle website janko.at, the concept of Tic-Tac-Logic was invented by Adolfo Zanellati, an Italian puzzle author who named his invention Tohu wa Vohu after the Biblical Hebrew phrase (תֹ֙הוּ֙ וָבֹ֔הוּ). Coincidentally, a similar puzzle was invented at the same time by PeterFrank, a media content company located in Belgium, who named their creation Binairo®. For more see Tic-Tac-Logic history.
