Thunder Herd — Free 1024 Ways Slot, Stacked Bison

How to play Thunder Herd

Thunder Herd is a five-reel, four-row video slot in the style of the big 1024-ways cabinets on a casino floor. There are no paylines to pick: every spin plays all 1,024 ways. Choose a bet multiple with BET − and BET + (1x, 2x, 3x, 5x or 10x, which is 40, 80, 120, 200 or 400 coins a spin), then tap SPIN or press Space. MAX BET jumps to 10x and spins. AUTO plays 25 spins in a row (tap again to stop) and TURBO makes the reels stop faster. Tap SPIN or the reels while they turn to stop them at once; the result was already decided when you pressed SPIN, so stopping early never changes it.

Ways to win: a symbol pays when it lands on reel 1 and on each reel next to it, left to right, in any row. Three in a row is the smallest win. The number of ways is the count on each reel multiplied together, so stacks of bison can pay hundreds of ways at once.
Sunset wild: appears on reels 2, 3 and 4 and substitutes for every symbol except the gold coin.
Gold coins: three, four or five anywhere start 8, 15 or 20 free spins and pay 2x, 10x or 50x your total bet.
Free spins: played at the bet that triggered them and cost nothing. Every sunset wild that is part of a win turns into x2 or x3, and when one way runs through two or three wilds the multipliers multiply: x2 and x3 make x6, three x3 wilds make x27. Two or more coins during free spins add 5, 8, 15 or 20 more spins. If you close the page mid-round, the free spins pick up where they stopped.
Thunder coin drop: on any paid spin a thunder coin can drop into the reels, about once every 8 spins, and pay 0.25x to 10x your bet on the spot. It has its own random roll, separate from the reels.
Stampede meter: every paid spin fills one step of the meter under the reels. At 30 steps it pays a Stampede bonus of 1x to 20x your average bet over those 30 spins, then starts again. The fill is saved, so it carries over to your next visit. Free spins do not fill it.
Skip: tap the reels or SPIN to finish a win count early.

Odds, honestly

We simulated 12 million paid spins of the exact game code, with free spins, retriggers, thunder coin drops and the Stampede meter all included. Thunder Herd pays back about 95.8 coins for every 100 bet over the long run: about 50 from ways wins, 3 from gold coin pays, 27.7 from free spins, 8 from thunder coin drops and 7.1 from the Stampede meter. About 40 spins in 100 win something on the reels (many of those wins are smaller than the bet), and something pays on about 42 spins in 100 once coin drops and Stampede bonuses are counted. Free spins start about once every 84 spins, last about 10 spins on average and pay about 23 times the bet on average, with a very wide spread. A thunder coin drops on 1 spin in 8 and averages 0.64 times the bet. The Stampede bonus comes every 30 paid spins and averages 2.1 times your average bet. Counting all three, a bonus of some kind lands about once every 6 spins. Every bet multiple has the same odds. Every spin is independent: the reels have no memory, nothing is "due", and a long dry run does not make a feature more likely. The Stampede meter is the one thing that does build up, and it shows you exactly how many spins are left. Because the long-run return is below 100, any stack of coins drains over time, which is exactly why the coins here are free and worthless.
