American Supercharge Slot by Genii

Two scatters, two totally separate feature paths, and they never touch each other. The one that runs during normal play is the paid Super Hits scatter. Every time one lands it ticks up a coin-collection meter along the top, and hitting the marked thresholds pays out on the spot: 20 coins at six, 40 at seven, 100 at eight, 200 at nine, climbing to 4,000 coins once you've stacked fifteen. Those payouts land on top of any line win, so the meter is its own quiet earner while the reels do their usual thing.

The free spins work on a different symbol and a genuinely odd structure. Three Free Spins scatters, which only ever land on reels 1, 3 and 5, hand you a stingy-looking three spins. But that's just the entry level. Inside the round, each Super Charge symbol that drops knocks one off a hidden counter, and when the counter empties the next level begins with three fresh spins, a cash prize, and a higher counter to grind down again. The prizes climb as you climb: 5 coins at level six, then 10, 25, 50, on up to 1,000 coins at level fifteen. So the round is really a ladder. Survive long enough to keep clearing counters and the per-level cash keeps getting bigger. It won't retrigger the old-fashioned way, the level engine is the top-up.

The Super Hits diamond logo doubles as the Wild, filling in for anything except those two scatters, and a card gamble sits on wins if you want to risk a payout on a coin flip. There's no buy option, so both features are earned cold.

Visually it's an unapologetic star-spangled cash grab. The gold-bordered grid sits over a rippling US flag in deep reds and blues, and the symbols are all wealth and Americana: stacked gold bars, a cut diamond, a silver Wall Street bull, a liberty bell, and chunky red-white-blue A, K and Q royals. It's the sort of straightforward, meter-driven collection build Genii tends to make, dressed up in flag bunting.
