Katmandu series
The Katmandu series took shape in 2020 when ELK Studios used Katmandu Gold to fix its adventure formula around six reels, colossal symbols and a play area that could expand. Its 6x4 setup offered 531,411 ways, medium volatility and a 10,000x maximum, with free spins, transforming symbols and multipliers supplying the main escalation.
Ranked by Slot Score
| Game | Year | RTP | Volatility | Slot Score |
|---|---|---|---|---|
 Katmandu GoldELK Studios | 2020 | 96.2% | Medium volatility | 77 |
 Katmandu XLatestELK Studios | 2023 | 95% | High volatility | 82 |
Katmandu X rebuilt that foundation as a 6x5 cluster-pays game with cascades, symbol swaps and colossal reels. The sequel raised volatility to high and the ceiling to 25,000x, while moving RTP from 96.2% to 95%. That combination makes X the more severe version: wins can feed further cascades and free-spin multipliers, but the mathematical profile asks for more tolerance between meaningful sequences.
The pair remains connected by oversized symbols, free spins, multipliers and optional bonus access. Gold expresses those ideas through an expanding multiway structure; X turns them into a cluster-and-cascade system with a substantially higher ceiling.
