Katmandu X: ELK Studios' 6x6 Cluster Slot
How the 6x6 Cluster Grid Works
The game plays across six reels each holding six symbols, for 36 positions in total. There are no paylines. A cluster forms when five or more matching symbols connect horizontally or vertically anywhere on the grid. Winning symbols are removed and new ones drop into the gaps in an avalanche style, so a single spin can chain into several consecutive wins. Pay symbols can also appear as big symbols, occupying blocks from 1x1 up to a 4x4 "Epic" size, which makes large clusters easier to assemble.
RTP and Volatility
Katmandu X runs at a 95% RTP, below the 96% loose industry yardstick. ELK classes the game as highly volatile: long quiet stretches are normal, with most of the return concentrated in the bonus and the bigger multiplier-fuelled clusters. A session balance that can absorb dry spells suits it best.
Wilds, Wild Strike and the Global Multiplier
The main base-game mechanic is the global multiplier. It climbs as winning symbols are collected during a spin's avalanches and applies to every cluster paid out, though it resets between base-game spins. Alongside standard wilds, the game features exploding wilds that clear surrounding symbols to trigger fresh drops, and multiplier wilds that feed the running multiplier. The Wild Strike feature can fire at random on any spin, sprinkling wilds, exploding wilds or multiplier wilds across the board.
Free Drops Bonus
Landing three bonus symbols triggers the free drops round. The difference here is that the global multiplier no longer resets between spins; it persists and keeps building for the whole feature, which is how the largest payouts come together. A Super Bonus variant guarantees a Super Wild Strike on every free drop, stacking wilds from the first spin onward.
X-iter Feature Buys
Katmandu X includes the X-iter menu, a set of five buy-in options that let you pay directly for enhanced spins or instant entry to the bonus, priced from a couple of times your stake up to several hundred. The published RTP for the X-iter purchases matches the base game's 95.0%, so buying in does not change the underlying maths, only the route you take to the features.
Max Win and Bet Range
The maximum win is capped at 25,000x your stake, reachable when stacked multipliers and large clusters align inside the free drops bonus. Stakes run from 0.20 per spin.
