Actually thrice :-) Gary's rollout code from rollout.c has:
  for( i = 0; i < cGames; i++ ) {
     if( prc->rngRollout != RNG_MANUAL )
InitRNGSeed( rcRollout.nSeed + ( i << 8 ), prc->rngRollout );
Since gnubg doesn't change the seed between rollouts of different moves
the same dice sequence will be used for each game.

Most embarassing. Just shows I have not looked at the rollout code for a long time. Joseph
