Big Bad Bison Review: x5 Multiplier Wilds & a Retrigger Ladder to 117,649 Megaways

Big Bad Bison: Retriggers, x5 Wilds & Megaways Progression

Quick Stats: Big Bad Bison reaches 117,649 Megaways, Big Time Gaming currently lists 96.59% RTP, and the provider publishes a maximum payout of 67,640x stake.

Big Bad Bison changes the Megaways floor rather than merely adding more spins to its bonus. Twelve Free Spins begin with a lower minimum number of active ways, then every Scatter retrigger raises that minimum for the remainder of the feature. After enough retriggers, every subsequent spin is guaranteed to run at the full 117,649 Megaways configuration. Big Time Gaming combines that progression with single-symbol Wilds capable of revealing multipliers up to x5.

Evolution classifies the game at the upper end of the volatility spectrum, while BTG's own launch material calls it very high volatility. Among titles in the online slot hub, Big Bad Bison is best distinguished by a Free Spins round that progressively raises the minimum reel density rather than resetting its Megaways configuration on every spin.

How Scatter Retriggers Raise the Minimum Megaways

Big Bad Bison uses Megaways™, meaning reel heights can vary from spin to spin and change the number of active winning combinations. The ceiling is 117,649 ways, but the game does not reserve its most important progression mechanic for that maximum configuration alone.

Single-position Wilds can appear during normal play and reveal a random multiplier of up to x5. When a multiplier Wild participates in a winning combination, its multiplier contributes to that win. The current 789Bingo page states that ordinary Wilds are limited to reels 2–5 and that multiple Wild multipliers involved in the same win multiply together; because BTG's public page confirms the x5 Wild system but does not expose those two finer rule details in text, both should be checked against the production paytable before being treated as structured specifications.

Landing three or more Scatters starts 12 Free Spins. The bonus does not simply add an accumulating multiplier. Instead, retriggers make the Megaways grid progressively denser. Two Scatters during a Free Spin add four spins, with another two spins for every Scatter beyond the second. Each retrigger also increases the minimum Megaways configuration for all remaining spins.

This creates a staircase effect: early bonus spins can use comparatively sparse configurations, while repeated retriggers push the minimum upward. Big Time Gaming states that after five or more retriggers, the game guarantees the full 117,649 Megaways on subsequent Free Spins.

789Bingo currently describes the individual progression levels as 64 → 729 → 4,096 → 15,625 → 46,656 → 117,649 ways. That sequence is mathematically consistent with increasing minimum reel densities, but BTG's public product page does not list every intermediate number, so the exact ladder should be confirmed in the in-game help file before being hard-coded across programmatic metadata.

For direct feature entry, BTG documents both Bonus Buy at 50x stake and Win Exchange™, subject to operator and jurisdictional availability.

Playing Big Bad Bison: Wilds, Scatters & Retrigger Progression

1. Create an Account or Sign In: Visit 789bingo and register or access an existing account.

2. Deposit Funds: Open the cashier, choose an available payment method and set a maximum entertainment budget before beginning.

3. Locate the Game: Browse the online slot hub and select Big Bad Bison by Big Time Gaming on 789Bingo.

4. Set Your Wager Size: BTG describes Big Bad Bison as very high volatility, so stakes should be sized relative to the whole bankroll rather than its 67,640x maximum payout.

5. Press Spin: Watch for x5-capable Multiplier Wilds and three Scatters for 12 Free Spins. Inside the feature, retriggering with two or more Scatters matters twice: it adds spins and raises the minimum Megaways density.

Pro Tip: Big Bad Bison can make a heavily retriggered Free Spins round look progressively stronger because later spins may be guaranteed more Megaways. That progression applies only after the required random retriggers occur; it does not make those retriggers predictable. With very high volatility, smaller wagers relative to a predetermined bankroll can provide more room for uneven results without chasing the next density increase.

Big Bad Bison RTP, Retrigger Ladder & x5 Wild FAQs

What is the RTP and volatility of Big Bad Bison?

BTG's current product page lists 96.59% RTP, while Evolution publishes 96.58% / 96.59%, suggesting multiple configurations. Big Time Gaming's launch announcement describes the game as very high volatility, while Evolution labels it High / Extreme. The production 789Bingo game-help panel should determine the exact RTP shown to players.

How does the Free Spins Megaways ladder work in Big Bad Bison?

Three Scatters award 12 Free Spins. During the bonus, two or more Scatters retrigger the feature and increase the minimum Megaways configuration for all remaining spins. BTG states that after at least five retriggers, subsequent Free Spins are guaranteed to operate at the full 117,649 Megaways level.

How do the Multiplier Wilds work in Big Bad Bison?

Wilds can reveal random multipliers up to x5. They can contribute their multiplier when involved in qualifying wins, including during Free Spins. The 789Bingo page additionally specifies reels 2–5 and multiplicative interaction between multiple Wild multipliers; those finer rules should be confirmed in the live paytable before being treated as universally applicable.

Keeping Limits Fixed as the Megaways Ladder Builds

Big Bad Bison combines very high volatility with a bonus whose potential can appear to increase after each retrigger. More Free Spins and a higher minimum Megaways configuration can make a long bonus sequence look increasingly favourable, but those mechanics do not change the need for predetermined spending limits.

Use only disposable entertainment funds and set the bankroll before starting. Deposit caps can limit the amount available for gambling, while session and time limits can stop repeated attempts to climb the Megaways retrigger ladder from extending play beyond the original plan.

Avoid chasing losses by raising stakes after unsuccessful spins or short Free Spins rounds. A bonus that failed to retrigger does not make a stronger one more likely next time. Bonus Buy and Win Exchange should also remain inside the same fixed budget; buying 12 Free Spins for 50x stake changes access to the feature but does not guarantee that the feature will repay its entry cost.

Timeouts can provide a temporary break, while self-exclusion offers a stronger restriction if needed. For official Philippine regulatory information, consult PAGCOR. PAGCOR's March 19, 2026 Evolution: Big Time Gaming list includes BIG BAD BISON, game version bigbadbisonv1000 - 1.0, classified as a Slot. PAGCOR Guarantee can be consulted for information about authorized online gaming providers, but it does not guarantee winnings or reimburse gambling losses.

The Bison bonus may become denser as retriggers accumulate; bankroll and time limits should never expand with it.
