It states on the small maroon rexine covered box - Waddy Production Main Line a THRILLING GAME THAT IS "different". Players - any number from 2 upwards. It should not exceed five if only one pack is used. Use two packs when players number 6 to 10. Cards - one pack consists of 50 cards showing various configurations of track with card values. Start - players are dealt cards, the number depending on how many players, and the remaining cards are left in a face down stack. Object of game - to get rid of all ones cards by laying cards so as to continue either the red main line or yellow branch line. Players either play one card or take a card from the remaining stack. The general idea is like a game of dominoes. At the end of a game players count up the points on cards still in hand. The Winner is the player with least [or no] points counting against him.
