Katmandu Gold
Katmandu Gold is ELK Studios' Himalayan-themed entry in the Gold series, played on a 6-reel grid that starts at four rows and expands up to nine during winning avalanche sequences. Winning symbols disappear and new ones fall in from above; consecutive wins grow the grid by adding rows. The game introduces Ice Climbers, special wild symbols that move directionally across the grid and fill gaps with further wilds. Big Symbols in 2x2, 3x3, and 4x4 sizes appear and contribute multiple positions to wins when they match. The multiplier in the Free Drops bonus has no cap, which is what makes the 10,000x ceiling possible. The RTP is 96.20%.
Key takeaways
- RTP: 96.20% at the base setting, rising to 96.30% with the base feature buy and 96.40% with the super option. Always verify in the info panel at your casino.
- Volatility: very high. The expanding grid and unlimited multiplier mean most sessions end well below the mean; large outcomes are rare but structurally achievable.
- Max win: 10,000x your stake, requiring a deep Free Drops round with a high multiplier and large matching symbol groups across the expanded grid.
- Expanding grid: starts at 6x4 and grows by one row per consecutive cascade win, reaching up to 6x9; more rows mean more ways to win on subsequent cascades.
- Ice Climbers: directional wild symbols that move across the grid filling gaps with wilds, extending cascade chains and contributing to win formation.

How Katmandu Gold works
Katmandu Gold uses an avalanche mechanic on a 6-reel grid that starts at four rows. Winning combinations of matching symbols are removed and new symbols fall from above to replace them. Any new cluster that forms in the same spin triggers another avalanche, chaining wins until no new combination appears.
The grid expansion is the primary structural feature. Each consecutive cascade win in a spin sequence adds one row up to a maximum of nine, giving later cascades in the chain more positions to work with. An avalanche sequence that starts on a 6x4 grid and runs five cascades deep resolves its fifth cascade on a 6x8 or 6x9 grid, where the increased symbol count creates more potential combinations.
The Himalayan theme carries through the symbol design: mountain equipment, jewels, and expedition motifs frame the reels with clean production values characteristic of ELK Studios.
Ice Climbers and cascade extension
Ice Climbers enter the grid as directional wild symbols. After each cascade, they advance one step in their programmed direction, leaving a standard wild in the position they vacated. An Ice Climber that starts at the bottom row and moves upward fills multiple positions over successive cascades before exiting the grid.
The practical effect is that Ice Climbers convert cascade gaps into wilds, completing combinations that would otherwise break the chain. A cascade sequence that would naturally end at two or three wins can extend further when Ice Climbers are active. This mechanical interaction between the avalanche system and the moving wilds is what distinguishes Katmandu Gold from simpler cascading titles.
Big Symbols: grid coverage and win size
The Big Symbol system contributes the second major mechanic. Super (2x2), Mega (3x3), and Epic (4x4) versions of standard symbols can appear anywhere on the grid. Because each position within a Big Symbol counts as a match, a 4x4 Epic symbol touching regular matching symbols creates a sixteen-position cluster from a single symbol appearance.
On an expanded grid during a deep cascade chain, a Big Symbol can contribute a large fraction of the total symbol positions to a single win. This is the direct route to Katmandu Gold’s largest wins: Ice Climbers extend the cascade, the grid expands, a Big Symbol lands in a high-value position, and the cascade multiplier during Free Drops applies to the result.
Free Drops and the unlimited multiplier
The Free Drops bonus triggers from scatter symbols in the base game. The round plays on the same expanding grid with the same avalanche mechanic and Ice Climber system. The addition is an uncapped multiplier that increments with each consecutive cascade win during the bonus. A cascade chain that runs to ten consecutive wins produces a 10x or higher multiplier before the chain breaks.
The uncapped nature of the multiplier is what creates the 10,000x ceiling. In base-game play, the grid expands but no persistent multiplier applies across wins in the same cascade sequence. In Free Drops, each win in the chain adds to the multiplier, and that multiplier applies to wins later in the same cascade. Reaching very high multiplier values requires a very long unbroken cascade chain, which is uncommon but structurally possible given the Ice Climber and Big Symbol interactions.
Bankroll and very high volatility
Very high volatility at Katmandu Gold is not the same as very high volatility on a standard payline slot. The cascade structure with grid expansion produces moderate wins more regularly than a bonus-only title. The very high volatility rating reflects the distribution of outcomes: moderate clusters keep the session ticking, but the large wins require the multiplier interaction during Free Drops and are substantially rarer.
Size your stake so the base game is sustainable over realistic session length, and treat Free Drops entry as its own event with a wide outcome range.

Frequently asked questions
What is the RTP of Katmandu Gold?
The base RTP of Katmandu Gold is 96.20%. ELK Studios publishes two bonus buy tiers: the base feature buy runs at 96.30% and the super option at 96.40%. Confirm the RTP shown in the game's info panel at your specific casino before playing, as operators may run different configurations.
What is the maximum win on Katmandu Gold?
The maximum win is 10,000x your stake. Reaching it requires a deep Free Drops round with a very high unlimited multiplier, a large matching symbol group across the expanded grid, and a high-value symbol match all combining in the same cascade chain. It is a rare but structurally achievable outcome within the game's mechanics.
How does the expanding grid work in Katmandu Gold?
The base grid starts at 6 reels by 4 rows. Each consecutive winning cascade adds one row, up to a maximum of 9. More rows mean more symbol positions and more potential combinations on the next drop. When the spin sequence ends without a further win, the grid resets to 4 rows for the next spin. Grid expansion in Free Drops works the same way.
What are Ice Climbers in Katmandu Gold?
Ice Climbers are directional wild symbols that move across the grid after each cascade, leaving a standard wild in every position they vacate. An Ice Climber active early in a cascade chain can contribute wilds to multiple subsequent positions before exiting the grid. This is how Katmandu Gold extends cascade sequences and charges the multiplier during Free Drops.
Is Katmandu Gold high volatility?
Katmandu Gold is rated very high volatility. The expanding grid and cascade structure produce moderate wins more regularly than a pure bonus-dependent title, but the game's large outcomes require the uncapped multiplier in Free Drops combined with Big Symbol and Ice Climber interactions. Most sessions end well below the game's mathematical mean.
Is Katmandu Gold suitable for bonus buy play?
A bonus buy is available that enters Free Drops directly. The base buy RTP is 96.30% and the super option 96.40%, marginal improvements over the 96.20% base figure. Very high volatility means Free Drops outcomes range widely, and repeated buys without a deep multiplier cascade deplete a balance quickly. The buy concentrates session variance in the bonus rather than spreading it across base-game play.
