Gonzo thought the hunt was over, but beyond the last ruins, a hidden trail has surfaced — one leading straight to El Dorado's greatest secret. NetEnt brings back the cult explorer for a second chapter of the legendary franchise — and this time every win physically expands the grid, while classic cascades give way to a system with two distinct Wild types and colossal symbols up to 4×4.

The facts: a starting 6×4 grid expanding to 6×8 in the base game, RTP of 96.06%, medium volatility, a hit frequency of 23%, a ceiling of 15,825x the bet, and up to 262,144 ways to win. The game runs on the Expanding Reels Feature and a two-Wild system — regular and Calamity — where the latter triggers an entire cascade of random wilds.

What actually makes the game tick?

Every spin begins with a 6×4 layout. As soon as a win occurs, the Expanding Reels Feature triggers — each Avalanche adds one row to the top, up to a maximum of 4 extra rows. In the base game, the feature ends once cascades stop, and the grid resets back to the original 6×4 for the next spin.

Two Wild types can appear on the reels — regular Wild and Calamity Wild. For any bet way starting with a combination of Wild symbols, the payout is determined by the highest value between an all-Wild combination or a regular symbol combination, whichever pays more. Combinations made entirely of Wilds only pay if they run the full 6 symbols from the leftmost to the rightmost reel.

When a Calamity Wild is part of a winning combination, the Random Wilds Feature triggers: before the play area expands and the next Avalanche begins, the Calamity Wild randomly places 3 to 6 regular Wild symbols on the reels — these can either fill empty positions or land over existing symbols (except Scatters, other Wilds, or unused Calamity Wilds).

Where's the big win hiding?

Scatters and high-win symbols (excluding Wilds themselves) can appear as colossal 2×2, 3×3, or 4×4 symbols on the reels. A 2×2 colossal Scatter counts as 2 regular Scatters, a 3×3 counts as 3, and a 4×4 counts as 4. During the Random Wilds Feature, colossal high-win symbols can also transform into colossal Wilds — up to two per spin.

💡 Free Spins vs Super Free Spins

Free Spins trigger with 3 or more regular-sized 1×1 scatters landing in succession from the leftmost reel, with no gaps — awarding 10, 12, 15, or 20 free spins. The global multiplier starts at x2 and increases by +2 with each Avalanche, resetting to x2 at the start of every new spin. The play area keeps expanding during Free Spins too, and any new rows gained stay in place for the following spin, up to a maximum height of 8 rows.

Super Free Spins activate when at least one of the scatters that triggered the bonus is colossal. The multiplier's starting value and growth rate depend on the size of the colossal scatter that triggered the feature: a 2×2 starts the round at x2 and increases by +2 per Avalanche, a 3×3 begins at x3 with +3 per Avalanche, and a 4×4 starts at x5 and increases by +5 each time.

If 3 or more scatters land in succession again during Free Spins or Super Free Spins, the same number of additional spins gets awarded for the respective mode.

For those who don't want to wait, five Elevate Feature tiers are available: Bonus Hunt (2x the bet, guarantees at least one Scatter symbol appears on the reels in the main game), Calamity Explosion (10x, guarantees at least one Calamity Wild is part of a winning combination), Calamity Max (30x, expands the reels to 8 rows and guarantees a Calamity Wild in a winning combination, with the expanded area carrying over into Free Spins or Super Free Spins if triggered), Free Spins (100x, guarantees 3-6 Scatter symbols with a small chance of activating Super Free Spins instead), and Super Free Spins (1000x, guarantees at least one colossal Scatter among the 3-6 symbols).

"Medium" volatility — how does it actually feel?

A 23% hit frequency is typical for a medium slot, but the combination of an expanding grid (up to 262,144 ways to win), colossal symbols, and stacking multipliers during free spins gives this game noticeably more depth and potential than a standard avalanche slot at the same volatility tier.

⚠️ 1000x for Super Free Spins — the priciest purchase

The top Elevate tier costs 1000x the bet for a single purchase. Even at a $1 stake, that's $1,000 per attempt — plan your budget before hitting buy.

⚡ Is Gonzo's Quest II: Return to El Dorado worth playing?

Go for it if you loved the original and want to see it in a much bigger version — the expanding grid, colossal symbols, and Super Free Spins' escalating multipliers genuinely raise the game's ceiling. If you'd rather have something simple without a long rules read, though, you'll need to learn the two-Wild system and free spin modes here before gauging the full 15,825x potential.
