Shopping Spree II on Thunderbolt: one symbol changes everything
Shopping Spree II is another of Thunderbolt's five RTG progressive jackpots, built around a wild symbol that decides whether a matching combo pays its full jackpot-tier value or a small fraction of it. Knowing which symbol carries that weight matters more than the theme itself.
Jackpot mechanic
The symbol that decides if you hit the jackpot tier
Shopping Spree II's wild is a "sale tag" symbol, and it's the single condition that separates a modest win from a jackpot-tier payout. Land five diamond rings on a payline without the sale tag present, and the payout is 5,000 credits; land that same five-diamond-ring combination on a line where the sale tag wild has substituted in, and the payout jumps to 50,000 credits, or in some builds the full progressive jackpot itself.
That's not a bonus multiplier layered on top of a normal win, it's a gate: the base combination alone caps out at a fraction of what's possible, and only the wild's presence on that specific payline unlocks the jackpot-tier number. Watching for the sale tag on active lines matters more here than tracking any other symbol in the game.
Bet structure
A different fixed bet than Aztec's Millions
Shopping Spree II runs on 9 fixed paylines at $0.25 per line, adding up to a mandatory $2.25 total bet per spin, with no line-count adjustment and no smaller stake available. That's a different fixed amount from Aztec's Millions, Thunderbolt's other RTG progressive covered elsewhere on this site, which locks players into a $5 bet instead — each jackpot title on the platform sets its own fixed number, so budgeting has to be checked per game rather than assumed to carry over.

Jackpot frequency
How often this jackpot actually triggers
Across the RTG network running Shopping Spree II, the progressive jackpot triggers roughly once per 2.4 million spins, a frequency that puts the win firmly in long-shot territory rather than something to expect within a normal session. That number also explains why the sale-tag-gated payout structure matters day to day far more than the jackpot itself, since most sessions will interact with the wild's smaller, non-jackpot payouts long before any progressive hit.
Playing it
Playing it on Thunderbolt
Real-money spins on Shopping Spree II feed the shared RTG jackpot pool at the fixed $2.25 bet, while fun mode runs the identical 9-payline, sale-tag mechanic without risking that stake. Since the RTP for this specific title isn't publicly disclosed the way Aztec's Millions' 95% figure is, fun-mode play is a reasonable way to get a feel for its actual volatility pattern before committing real funds.
