As Don stated in his 7.7M submission thread, and I'm sure a number of times during previous Twin Galaxies ownerships, the wording for the forbidden strategy in the rules is wrong. The spider may never be trapped in the game of Centipede, however, the Centipede itself may be. Here's a YouTube video that I linked in my 790k submission thread demonstrating the technique: https://www.youtube.com/watch?v=8Cn7XRvVk-0 Lastly, there're other techniques that Don and I would've preferred to have been disallowed in the rules (ones that delay the advancement of the game, mostly by preventing the fleas from dropping), such as the "Blob Strategy", but Franz's score above already utilized it, well before most of the scores were on this leaderboard, as documented on pages 124-125 of this pdf file of The Video Master's Guide to Centipede: https://www.digitpress.com/library/books/book_vmg_centipede.pdf -Duc
