Bison Moon: Thunder Charge Slot Review

Before anybody could read a barometer, the Plains tribes already knew what a thunderstorm was: a giant eagle 🦅 the size of a war canoe, beating the thunder out of the sky with its wings and firing lightning ⚡ from its eyes.

This Thunderbird was no bedtime mascot. It hunted whales, feuded with a horned water serpent, and if it turned your way mid-storm, that was the whole point of the story.

Quickfire borrows that exact bird for Bison Moon: Thunder Charge slot and calls it the Lightning Eagle. Gather it across all 5 reels and the storm pays off the old-fashioned way, a jackpot wheel spinning under a full moon 🌙.

Gameplay

The backdrop is a sunset prairie: purple mountains, tall grass, a red moon climbing behind the logo, and a jackpot wheel bolted to the left of the reels.

After some of the cluttered grids I've squinted at this month, a clean plains layout is a relief.

You're on a 5x3 grid across 25 paylines. The RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate. is 96.05% and the volatility is high. Wins top out at a max multiplier of 12,500x, worth a max win of $250,000.

Bets run from $0.20 to $20. It's fiat only, which locks out my crypto bros and the Japanese yen both.

The paytable's high end is a wildlife pecking order: the Bear symbol runs the show at 25x for 5-of-a-kind, with the Wolf, Eagle, and Raccoon symbols falling in behind on 15x, 10.5x, and 7.5x respectively.

Below them the low-paying symbols put in the usual thankless shift, the A symbol paying 4x for 5-of-a-kind and the K, Q, and J symbols bringing up the rear on 3x, 2.5x, and 2x respectively.

The Bison Wild is the one you're chasing out there, worth 500x for 5-of-a-kind before a steep drop to 20x for 4 and 2.5x for 3. It fills in for every regular symbol and only turns up in the base game.

The Red Moon is the symbol the whole game is built to hand you. It drops in the base round already carrying a cash prize, and collecting enough of them opens every door worth walking through.

Five jackpots ride the wheel off to the side: Mini at 10x, Minor at 30x, Major at 100x, Mega at 500x, and the Grand sitting up at 5,000x.

Features

THUNDER CHARGE BONUS:

Land 6 or more Red Moons to fire the Thunder Charge Bonus, the hold-and-win that's the whole reason anyone loads the game up. The cash those triggering moons were showing rides in with you.

You drop onto a taller board with rows 1 and 6 chained off and 3 respins on the clock. Every Blue Moon that lands sticks with its cash value showing, and the counter jumps back to 3 the moment anything new arrives.

The Bison Moon Cash Prize riding over the board fattens on every payout, and 2 Key symbols apiece spring the locked rows.

Carpet the whole board in moons and the Grand Jackpot is yours, which is about as rare as it sounds.

STELLAR MOON BONUS:

Land 5 Red Moons instead and you trip the Stellar Moon Bonus, which grabs every moon prize on the board and blows the whole pile up by anything from 1x to a full 100x. Catch that 100x and you'll remember it.

MOON COLLECTOR BONUS:

There's a Moon Collector Bonus too, sparked at random by Red Moons, and it's the game nudging things your way on the sly.

It hoovers up the moons already down and tosses fresh ones across the reels, enough to kick off or fatten the Stellar Moon Bonus or the Thunder Charge Bonus.

BISON STAMPEDE:

Any base spin can end with a Bison Stampede rumbling in unannounced. The herd tears across the reels and forces the game down 1 of 2 roads.

Down one road, Wilds splash across random reels and pay off whatever lines they finish. Down the other, 6 or more Red Moons crash in and drop you straight into the Thunder Charge Bonus.

LIGHTNING EAGLE JACKPOT:

Here's where the Thunderbird finally earns its keep. The Lightning Eagle symbol collects on a meter below the grid, and landing it on all 5 reels spins up the Lightning Eagle Jackpot Wheel.

The wheel runs 2 rows, and each one hands over a jackpot, a cash prize between 5x and 250x, or another run at the Thunder Charge Bonus.

BUY BONUS AND ANTE BET:

If you can't wait for the moons to cooperate, the Buy Bonus sells the Thunder Charge Bonus for 100x your bet, or the Super Thunder Charge Bonus for 200x, which is the same round with more Blue Moons crammed in.

The Ante BetAn Ante Bet is an option that costs a percentage of your bet but increases your chances of landing triggering symbols that initiate a feature., which the game insists on branding the Charged Bet, runs 2.5x your normal bet to seed extra Red Moons and trigger the round more often. It leaves your line wins and moon pays untouched.

Performance

I ran a long, greedy session on the slot and it didn't cough once, the base reels and that tall six-row bonus board both loading the second I asked.

Maximum Win

The headline is a $250,000 max win, built from the max multiplier of 12,500x firing at the $20 top bet. The floor under all of it is a $0.20 bet.

Conclusion

The slot's money comes off the Thunder Charge Bonus, above all the Bison Moon Cash Prize that doubles on every payout. Keep the moons landing and that number runs away fast.

To touch the max multiplier you'd need to jam the six-row board full and drive the Bison Moon prize way up its ladder, or paper the whole board with moons for the Grand Jackpot.

Rare stuff, but the pile of trigger routes gives more cracks at the round than most games do.

RTP needs to be considered in conjunction with a game’s volatility rate. runs high enough that the slot plays for the long haul, so your balance won't evaporate in a handful of spins.

The swings are brutal, yet the max multiplier is sized to match them rather than fall short, which is more than most high-variance slots ever manage.

The Buy Bonus is worth a look, dropping you into the hold-and-win, and the Super tier only earns its price if you want more Blue Moons. The Ante BetAn Ante Bet is an option that costs a percentage of your bet but increases your chances of landing triggering symbols that initiate a feature. is the quieter toll for grinding the feature up over time.

Feature-hunters are the target, the players who want a stack of doors into a bonus. Anyone who'd sooner grind steady line pays and small, regular wins will find the base game thin.
