More than 2 players adds another level of complexity: alliances. Snake is a bit like Risk in that it's possible to attack a specific player while signalling intent. We should expect any proper AI to read and understand the others and work out who should be avoided or ganged up on. Rock-Paper-Scissors tournaments have bots that use game moves to recognize eachother and then dump all their points onto a single player -- something similar could happen in Snake as well.
