Players don’t have an option of how much they wish to wager in Jackpot 7 as such. Instead, the amount they wager per line (of seven numbers) is fixed. What does change is the number of lines that the player selects. Rather obviously, the more lines the player has, the more likely they are to win, although the more money it will cost.
The interesting thing here is that the player is paid out according to each individual digit they correctly predict from the combination. The jackpot is progressive and so it rises and rises until it is won, and the player can see the pay table on the right hand side of the screen, that will tell them what they have won. Players have the option to either enter their own digits via the keypad, or click the random line button to have seven numbers (or more) randomly chosen for them.
