Extra Cash!! Slot by Light & Wonder

Most of the action lives in the free spins, and the paperboy runs it. Land three, four, or five of the rolled-newspaper scatters and you get 8, 12, or 20 spins, or 20 straight away if five scatters land in a single base spin. The rule that makes the round build is that any Extra! Wild stays held for the rest of the free games, and the paperboy keeps tossing fresh wilds on top, so the grid gets denser with each spin instead of resetting. By the back half of a good run the 5x4 board can be carrying a stack of locked wilds at once.

Before you even reach the free games there's a respin to chase. Two, three, or four scatters lock the reels showing them and respin the rest once, giving you a second shot at landing the third scatter and tipping into the feature. It can't retrigger, but it noticeably softens the medium swings since near-misses get a free retry rather than just vanishing. There's also a separate Extra Wild touch in the base game, where a wild can be randomly dropped onto the middle three reels after any spin.

The theme is cheerful 1920s newsboy Americana. A beagle puppy peeks out from a folded newspaper, a flat-capped paperboy hawks headlines from a red-brick city street with a sack of papers and a wooden FRAGILE crate, and the symbol set runs through newspaper stacks, a vintage delivery truck, a red news wagon, and bright card royals on a paper-white backdrop. After a win the optional double-up gamble offers red or black for double or the exact suit for four times. For more games built on locked wilds, the sticky wilds tag is the place to look, alongside the rest of the money shelf.
