I don't think this works. If both twins do the same thing, they pass at the other end of the universe. Each looks out of the spaceship and sees the other one as older. No one loses, but the game is never over because the twins don't end up at the same place at the same time and speed.yes, bhutes has pointed out that my strategy does not guarantee you to win.But it guarantees you not to loose- and I think its the only strategy that gives you that guarantee.But suppose Jack does this strategy. Jill stops and waits for Jack to approach her from the other direction. She accelerates away from him, but at less than maximum velocity. She gradually speeds up until Jack catches up and they are going the same speed. Jill will be younger, and will win the game.I am not sure if this is correct.In the inertial frame of Jack, Jill acelarates (several times), so if we compare their the ages in this reference frame (which is common for both of them in the final state) Jill will be older.
