The £1 1 line pays more, so if I play £1 1 line and hit 2 premium symbols I win £5, if I played the 10 lines and had a total stake of £1 I think it’s 50p or £1 win , the game pays as if it’s a £10 stake I’m playing with if that makes sense, I only play on book of dead or lord of the ocean on the 1 line, and had retriggers and premium symbols, 1 full screen a few 3 expanding and then 4. I’ve had explorers twice and never had more than 2 expanding
