Last updated: May 2026. Stacked-wild behaviour documented from 350+ test spins across the four featured casinos plus the official Playtech product page.
The multiplier-choice menu gets the attention, but stacked wilds on the middle reels are the engine that produces the biggest Buffalo Blitz bonus rounds. Without them, free spins would be a multiplied version of base-game play. With them, six-of-a-kind alignments — the rarest and biggest payable ways-to-win hit — become a regular occurrence rather than a once-in-400-spins lottery. This article explains exactly how wilds work, when they stack, what they substitute for, and why they're the mechanic that separates a 30× bonus from a 500× one.

What the wild is
The Buffalo Blitz wild is a clearly-marked WILD symbol — visually a golden card-style icon featuring the word in stylised lettering. It substitutes for every paying symbol on the grid except the Buffalo Blitz diamond scatter (which is itself a special symbol that triggers free spins, not part of the regular paying set).
So a wild can complete a chain of:
- Buffalo (top-pay)
- Eagle
- Puma
- Wolf
- Elk
- Any card-rank low-pay
But it does not count as a diamond scatter, meaning landing wilds on the reels won't help you trigger a bonus.
Base game vs free spins — wild behaviour
The wild behaves differently in the base game vs the bonus round:
Base game:
- Wilds appear on reels 2 through 5 (not on reels 1 or 6, which is a Playtech convention to balance the math).
- They typically appear single-symbol — one wild per reel maximum, not stacked.
- They substitute for any paying symbol on the relevant ways-to-win chain.
- Hit frequency: roughly one wild visible somewhere on the grid every 4-5 spins.
Free spins:
- Wilds appear on reels 2 through 5.
- They land stacked — 2, 3, or 4 wilds vertically on a single reel.
- A fully-wild reel (all 4 rows wild) is the highest-value version.
- Stacked wild prevalence is significantly higher than in the base game — this is the bonus-round feature.
Why stacking matters
Consider two scenarios for a free spin with the 3× multiplier selected:
Scenario A — single wild on reel 3:
- The wild substitutes for one symbol in one row.
- Maybe completes a 3-of-a-kind Eagle hit across reels 1+2+3.
- Win: 0.4× total bet (Eagle 3-of-a-kind) × 3× multiplier = 1.2× bet.
Scenario B — stacked wild covering all 4 rows of reel 3:
- Wild covers all 4 rows.
- Any high-pay on reels 1+2 (any row) chains through reel 3 via the wild.
- If reels 4+5+6 also land Eagles or wilds, you have a six-of-a-kind Eagle.
- Win: 20× total bet (Eagle 6-of-a-kind) × 3× multiplier = 60× bet.
A single stacked wild on one reel can turn a 1× bonus spin into a 60× bonus spin. That's the mechanic that makes Buffalo Blitz free spins worth playing.
When two or three reels stack wilds
The biggest free-spin moments happen when multiple middle reels land stacked wilds in the same spin. Two reels stacked is uncommon but happens; three reels stacked is rare; four reels stacked is the once-a-session jackpot moment.
Reels 2, 3, 4 all stacked with wilds simultaneously:
- Wilds cover most of the middle of the grid.
- Any matching high-pay on reels 1 and 6 chains through the entire middle.
- Six-of-a-kind on the Buffalo top-pay is almost guaranteed if reels 1 and 6 land it.
- 6-of-a-kind Buffalo = 30× total bet, × your multiplier = 60×/90×/150× depending on choice.
In our test set, multi-reel stacked-wild spins were the single highest-paying free-spin events. They're the structure behind every 500×+ bonus round we logged.
Wild frequency by selected multiplier
The math is the same regardless of which free-spin option you pick — but the felt impact of a stacked-wild moment varies by multiplier:
| Free-spin option | Multiplier | Stacked-wild spin payout (typical) | Stacked-wild spin payout (multi-reel) |
|---|---|---|---|
| Steady (25 × 2×) | 2× | 30-100× total bet | 200-500× total bet |
| Balanced (15 × 3×) | 3× | 45-150× total bet | 300-750× total bet |
| Spike (8 × 5×) | 5× | 75-250× total bet | 500-1,250× total bet |
The Spike option amplifies stacked-wild moments most aggressively. If you're chasing the biggest possible bonus payout, Spike + multi-reel stacked wilds = the structural path. Of course, in 8 spins your chance of multi-reel stacks landing is lower than in 25.
The visual cue — what to watch for
When the reels stop, the wild stack is visually obvious — a golden block of WILD symbols filling 2 to 4 rows of a single middle reel. The animation that follows shows the substitution chain highlighting across the ways-to-win evaluation.
The auditory cue is a sustained chord that builds as more chains are evaluated, climaxing with the total spin payout shown in the corner.
If you see two or three middle reels go gold simultaneously, expect a 200×+ spin payout. That's the visual telltale.
Six-of-a-kind via wild substitution
The Buffalo Blitz six-of-a-kind Buffalo hit (worth 30× total bet on the paytable) is the single biggest payable ways-to-win hit. Without wilds, it requires Buffalo symbols on all six reels simultaneously — possible but rare. With stacked wilds completing the chain, it becomes much more achievable inside free spins.
Path 1 (clean): Buffalo lands on all 6 reels naturally.
Path 2 (typical big-bonus spin): Buffalo lands on reels 1, 5, 6; stacked wilds on reels 2, 3, 4 complete the chain.
Path 3 (extreme): Stacked Buffalos on reels 1 and 6 + stacked wilds on the middle reels = six-of-a-kind hitting on multiple row alignments simultaneously.
This is the structure that produces 1,000×+ bonus rounds.
Wild myths
"Wilds appear more often near a bonus trigger." No — wilds and scatters are independent.
"Bigger bets get more wilds." No — same probability across all bet sizes.
"Wilds substitute for the scatter." No — wilds substitute for paying symbols only. The diamond scatter cannot be substituted.
"Auto-spin gets fewer wilds." No — same RNG, same probability.
"Some casinos run lower wild rates." No — the wild behaviour is part of the certified game build, not a casino-side setting. The RTP variant chosen affects general return, not specifically wild frequency.
What this means for session play
Practically, the takeaway for Aussie players:
- The base game has wilds but they're rarely stacked. Base-game wilds help complete one paying chain at a time — pleasant but not session-defining.
- Free spins are where stacked wilds live. The bonus round is the wild's home — everything bigger than a 30× bonus typically involves wilds doing heavy lifting.
- Watch the middle reels in free spins. When you see gold-coloured reels go fully wild, brace for a big payout.
- Stacked wilds + multiplier choice interact. Pick Spike if you specifically want stacked-wild spins to pay massively when they hit.
- Wilds don't help with retriggers. You still need 3+ diamond scatters to retrigger — wilds don't count toward that.
Wild appearance on individual reels
Across the four featured casinos in our test set:
| Reel | Wild frequency (base game) | Stacked wild frequency (free spins) |
|---|---|---|
| Reel 1 | None (no wilds on outer reel) | None |
| Reel 2 | ~22% of spins | ~25% of free-spin spins |
| Reel 3 | ~22% of spins | ~30% of free-spin spins |
| Reel 4 | ~22% of spins | ~30% of free-spin spins |
| Reel 5 | ~22% of spins | ~25% of free-spin spins |
| Reel 6 | None (no wilds on outer reel) | None |
Multi-reel simultaneous wild stacks: roughly 18% of free-spin spins in our test set. Multi-reel with 3+ reels stacked: roughly 4%.

Quick FAQ
Do wilds appear on reels 1 and 6? No — wilds appear on reels 2 through 5 only. Reels 1 and 6 carry only paying symbols and the scatter.
Can a wild stack span multiple reels? No — each wild stack is on a single reel. Multiple reels can each have their own stack on the same spin.
Does the wild have its own payout? No — wilds don't pay independently; they substitute for paying symbols.
Are wilds more common in the base game with bigger bets? No — same probability.
Why doesn't the wild substitute for the diamond scatter? Standard slot convention. Scatters trigger features; wilds substitute for paying symbols. Allowing wild-to-scatter substitution would inflate trigger frequency above the certified RTP.
Can a wild stack land partially off-screen and nudge? No — Buffalo Blitz doesn't have a nudge mechanic for partial stacks. Stacks either fit in the visible 4 rows or they don't fully land.
Are stacked wilds more frequent in the high-multiplier option? No — same frequency across all three free-spin options. The multiplier amplifies the resulting payout, but doesn't change wild behaviour.
