Tangentially related: The episode that just ended on Buzzr had something I didn't recall seeing before: a three-way tie that forced a non-round-number money total for each section, rounded up to $584.
I remember a number of 3-way ties, and each one had each couple get an extra $334. I assume this was because had it been 333, that would have only been 999, instead of the "promised" 1000, and Standards & Practices would have had an issue. I remember the original
JackPot! had a similar "problem"; at the beginning of each episode, Don Pardo's spiel said that a riddle could be worth "up to $50,000," but the largest target was 995, so in theory, the largest Super Jackpot was only $49,750 (well, if you don't count the one time the board malfunctioned and the multiplier was 55); Geoff said in one episode that if that ever happened, they would add $250 to make it an even $50,000.
