Bison Valley (iSoftBet) – Review & Demo Play

Bison Valley Slot Overview

As I sat down with Bison Valley from iSoftBet, it felt like a straight-up revisit of Golden Buffalo Double Up, only with fresher visuals and a Morricone-tinged soundtrack. The 5x4 grid delivers 1,024 ways, and the whole cadence revolves around landing Bonus Wheel scatters. That wheel either grants free spins or fixed cash prizes up to 1,000x, with the top game potential capped at 5,998x. Wilds sit on reels 2–4, doing the heavy lifting in both phases, while the ante-style Double Up nudges feature hit rates.

Bison Valley Slot Information

Bison Valley runs on 5 reels, 4 rows, and 1,024 ways to win. Bets range from 0.20 to 20 per spin, with a stated RTP of 96.00% and mid-high volatility. Hit frequency lands at about 32.2%, so roughly a third of spins connect. To score, wins start from the leftmost reel on adjacent reels. Grand, Major, and Mini prizes sit above the reels as fixed awards worth 1,000x, 100x, and 50x respectively, and they can drop via the Bonus Wheel.

The paytable splits cleanly. Low symbols are 9, 10, J, Q, K, and A, paying around 5x to 7x for five of a kind. High symbols are squirrel, bird, armadillo, fox, and the golden bison, paying 7.5x up to 15x for five. Wilds appear only on reels 2, 3, and 4, one per reel, subbing for pays but not the scatter. The golden bison can turn stacked during free spins, shifting most of the line-hit weight onto the premiums.

Bison Valley Slot Features

The Bonus Wheel drives progression. Land 3, 4, or 5 scatters for 1, 2, or 3 spins on the wheel. Each spin can award 8, 10, 12, or 15 free spins or a fixed cash prize such as Mini 50x, Major 100x, or Grand 1,000x. There’s also a Bonus Buy at 100x the bet that buys you a wheel spin. In markets where it’s present, that option shortcuts the slog, though I usually weigh it against the game’s volatility and my session bankroll.

Double Up is the ante switch before a base spin. It doubles the stake and increases Bonus Wheel trigger odds from about 1 in 200 to 1 in 115. Scatters become two rows high when it’s active, and they count whether they land fully or partially. In the base, wilds on reels 2–4 are your setup pieces. One per reel can land, setting up those 1,024-way connections, and keeping the screen ticking until the wheel turns up.

Free spins pick up the pace. Wilds can arrive with 2x or 3x multipliers, and when more than one joins the same win they multiply together to reach up to 27x. The golden bison turns up stacked at times, which pairs nicely with the multiplier wilds. You can extend the round by landing 2, 3, 4, or 5 scatters for 5, 8, 15, or 20 extra spins. The loop blends stackable top symbols, multiplying wilds, and retriggers chasing another premium cluster.

Bison Valley - Review Summary

I read Bison Valley as a competent remake that modernises the look but keeps the maths and feature flow from Golden Buffalo Double Up. The Double Up switch pulls its weight if the budget allows, while the wheel-only entry to free spins can feel a bit gated. Jackpots are fine for table-fill but not the main draw; the multiplying wilds are. With 5,998x top, 96% RTP, and a brisk hit rate, it plays steady, and some markets use variable RTP, so I check the info panel.
