A wild acts as others to complete extra combinations. Any win triggers a Tumbling Reels feature, that removes any winning symbols and allows those above to drop down. Tumbles repeat with no limit, and only end on a non-winning mix of symbols.
The number of locked or hidden symbols varies, but you always have 3 – 5 rows on each reel. Four random blockers open up on each tumble in a series, and you could build to a maximum of 117,649 ways to win.
The main feature of the Cash Truck 2 online slot is a respins round, triggered by three or more bonus scatter symbols. You get three respins with blank spaces, cash stack money symbols, and a bunch of modifiers. Any active symbol resets the spin counter back to three.
Modifiers include Expanders that increase the play area, Boosters and Super Boosters that add their values to other symbols, and Doublers that double in value on each retrigger. Grabbers add the value of symbols in unlocked areas, while Super Grabbers do this for every remaining respin. Cloners place the highest value symbols into random places, and Compressors add the value of all cash symbols to themselves.
This feature of the Cash Truck 2 slot machine runs until you fill the grid or get three spins in a row with only blanks. Then the heist is complete, and you grab all cash values.
