Slot Summary

Pick one of three concealed free-spin awards, then let Greenback Attack's two bonus systems cross paths. IGT ties its comic money-box theme to independent respin reels, while the separate free-spins round can trigger that cash-collection feature again. The result is a 30-payline game whose identity comes from switching between ordinary line wins and scatter prizes that ignore paylines.

How It Plays

Thirty paylines handle the base game from left to right, with the wild substituting for ordinary symbols but not the Free Spins or Dollar Bill symbols.

Dollar Bill scatters shift play away from paylines. Reels holding those scatters become active separately, and each new scatter refreshes only the relevant reel's respin counter.

Theme & Atmosphere

Animals and Cartoon styling turn the Money box subject into a light comic caper, keeping the cash-collection premise readable without treating it as a conventional bank-vault story.

Crown imagery marks the fixed Piggy Prizes above the reels, giving the theme a visible hierarchy as individual cash awards accumulate below them.

Features & Win Potential

The Hold and Win structure separates active reels from inactive ones. Scatter prizes collect without paylines, and filling every position on an active reel awards its corresponding fixed jackpot.

Wild symbols support ordinary line wins, while the symbol-collection system supplies the bonus its energy. Respins continue until every active reel exhausts its remaining chances.

Bonus & Free Spins

Free spins begin with a pick among three concealed awards. The round retains the triggering coin value and paylines, while the Greenback Attack Bonus remains eligible to activate again.

Within the respin bonus, newly landed scatters reset an active reel to three spins. The feature closes when no reel has a spin remaining or its stated limit is reached.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.06%), with wins capped at its top multiplier (25,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.

01How does the Greenback Attack Bonus work?

Triggering scatters activate their reels and remain locked while each active reel receives three independent respins. A new scatter adds its displayed prize and resets that reel's counter.

02What triggers the free spins in Greenback Attack?

Three Free Spins symbols on reels 2, 3, and 4 activate the round. A pick then reveals an award ranging from 8 to 20 free spins.

03Can the respin bonus appear during free spins?

Yes. The Greenback Attack Bonus remains available during free spins, so its independent-reel respins can interrupt the free-spin sequence more than once.
