X-Ceter-O, another imminent release from Endless Games, is a packaged game nearly identical to the age-old game Three Men’s Morris.

Each player has three numbered pieces: O’s are numbered 1,3, and 5, and X’s are numbered 2,4,6 . Players alternate placing or moving the stones on the board, in numerical order, starting again from 1 when all stones have been moved or placed.

Aside from the strict numerical ordering, this is Three Men’s Morris. But it’s packaged as “an imaginative twist on the classic game [of Tic Tac Toe], incorporating elements of chess and other strategy games,” with a claim that a tie is not possible.
