The biggest (monetarily speaking) addition to the line is the Super Grand jackpot, another linked jackpot that sits above the standard Grand in this game format.
It makes sense given the popularity of the series to wring more money out of the game, especially with some of the other changes that are made to the game, but also has the effect of making the sequel more expensive. This doubles the minimum bet on the game. That has the effect of raising the minimum bet to $1 a spin, which matches the 50 lines at 2 cents. You’ll notice that on pennies you now must wager 100 lines.
Some of the denominations differ from the predecessors. Like its predecessors, the number of lines is in part determined by the denomination selected. The game’s default configuration supports a whopping 8 denominations, from 1 cent all the way to $5. Like Dragon Link before it, Dollar Storm expands the number of denominations it supports.
