How to calculate payline wins

  • To calculate your total win, calculate all payline wins and add them together;
  • To calculate a single payline win, count the number of identical symbols lined up in the sequence on the line starting from left to right;
  • If three or more identical symbols lined up, find the win value in the Pay Table. There you can find the value for 3 in a row, 4 in a row and 5 in a row — for all symbols. Only the highest winning combination per line is paid out;
  • If the winning combination starts with three Wilds, there can be many ways to interpret the win. In this scenario, only the highest win combination is paid out;
