Bison Gallop Slot by YGR

Eight to ten free spins in, the reel pool doesn't look like the one you started with. Card royals start vanishing, replaced one by one with bison icons, and the cascades keep landing denser and more valuable as the round goes on. That progression is the entire strategic hook of Bison Gallop and it only exists inside Free Games. Gold Coins drop onto the grid during FG spins and tick a hidden counter upward. Every third coin locks one low-tier symbol out of the pool for the rest of the round, the letter or number is jailed, and its slot is refilled with a Bison. Next cascade, fewer 9s and 10s show up. Next one after that, fewer still. Run the round long enough and the A, J, 9 and 10 are all gone, the pool is pure bison, and coins stop appearing because the transformation is finished.

Which is where the retrigger design earns attention. Initial entry needs 3 scatters for 10 spins, with +4 per extra scatter (14 at 4, 18 at 5, 22 at 6). But inside an active Free Games round, 2 scatters is already enough to extend it, awarding +5 spins plus +2 for each extra. That 2-scatter threshold is deliberately gentler than the 3-scatter entry, so the door stays open for longer sessions, which matters a lot when your reel pool is still shedding low-pays. The longer the FG lasts, the more time the cleansing mechanic has to finish its work.

Base game is a cleaner story: six reels of Megaways ways topping out at 117,649, cascade-style drops after every hit, and Wilds pinned to reels 2 through 6 only. No Wild lands on reel one, ever. Each Wild that takes part in a winning line carries a random x1 to x5 multiplier on that payout, so a single stacked cascade can multiply its own tail. The Buy Bonus sits at 50x stake, tied for the cheapest shortcut in the YGR catalogue and half the price most providers charge, which is the single most generous cost in the whole build. No persistent jackpot attached, no max-win figure disclosed, the top line runs through a bison-saturated Free Games session with x5 multipliers firing on compound cascades.

The setting is Great Plains cowboy country at dusk. Red mesas and striated sandstone rise behind the reels under a lavender-blue sky, the reel frame is a weathered beige panel bordered by a twisted tan-and-gold cowboy rope, and the symbols lean into the American Wild West wildlife expected of a frontier theme: shaggy brown bison, antlered deer, a standing wolf as likely top-pay. Card royals keep the low tier visually loud with red A, green J, blue 9 and orange 10 on white tiles, at least until the bison transformation starts quietly erasing them from the board.
