As is usually the way with Nolimit City slots, it takes a while to figure out the details but when you get there, it's worth the effort. It isn't immediately clear what is happening during the feature rounds, but if you just think of it as Respin Bonus that keeps getting upgraded, then you won't be far off the mark.
Before getting to the features, let's take a look at the regular Base game. There are two different symbol sets to look out for with one special set being reserved for the feature games. What you are working with, for the most part, are 10 symbols increasing in value all the way from the plastic bag up to Billy—one of the main characters who we’ll meet soon. 5 of his symbols landing on consecutive reels will bring you a 7.5 x payout.
The Bonus Action
Scatter symbols will trigger the first 2 features and only 2 of them are required to get things going. This is where we find Call to Arms. The central 3 reels now play a prominent role in the Respin Feature where you have 2 lives and 2 Jumping Wild symbols. Hilly and Billy now get in their vehicles and try to cross the grid.
If a Wild is struck by a car, your lives remain intact and an extra hit point gets added to the corresponding Collector symbol above. Once this reaches 5, the symbol gets upgraded. Two trips across the grid without striking an animal means the end of the feature.
The 3 Jumping Wilds are Papa Bear, Deer Joe and Fred the Rabbit. Without getting too bogged down by the exact details, the bear can add Multipliers, the deer can split symbols to increase the win ways and the rabbit can produce further Wild symbols.
if an extra scatter symbol lands during Call to Arms, the game is upgraded to Team Assemble. You now get an extra life and the respins continue as before. This gives you a chance to upgrade all of the Jumping Wilds and brings about the Junkyard Assault stage.
During Junkyard Assault, your hearts get armoured, which effectively doubles their value, and you'll see the red car with every spin, which is more frequent than it was in the previous stages.
The final part of the process is achieved by collecting 20 hits on your Jumping Wilds—this triggers the Roadblock. Your lives now get restored and the Wilds cover the rows. This Roadblock is a giant Wild symbol and as the cars hit it, some symbols will split, Wilds get added and Multipliers begin to grow.
