Cygnus 4 Slot by ELK Studios

Fourth entry in the Cygnus series, and the Multiplier Pillar is still the centrepiece. It works in 6 steps across 3 levels. Level 1 runs x2 through x16. Level 2 pushes x4 to x32. Level 3 starts at x8 and its sixth step triggers the full 50,000x payout instantly, no calculation needed. Multiplier symbols advance the pillar one step when they reach the leftmost column or the bottom of the grid, then convert into Wilds. Land a Level Up symbol and the entire pillar rotates to the next tier while keeping your current step position. If both a multiplier symbol and a Level Up land in the same avalanche, the level up processes first - meaning you get the upgraded values before the step advances.

The expanding grid adds a row with each winning avalanche, stretching from 4 rows up to 8. That takes you from 4,096 ways to 262,144. The multiplier resets to 1x every new spin, so all the pillar progress needs to happen within one round or carry into Free Drops. Seven Free Drops trigger when the Bonus symbol reaches the leftmost column, and the pillar level plus current multiplier stay persistent through all of them. Retriggers add 3 more drops. There is also a re-drop mechanic: if the Bonus symbol lands on the bottom row in columns 2 through 6, the game removes it and drops it again one column to the left, giving it a second shot at that trigger position. Only happens once per avalanche cycle.

Five X-iter tiers sit above normal play. The 10x option starts the pillar at Level 3, which is appealing since those multipliers begin at x8. At 25x, multiplier symbols double as Wilds throughout your session. The 100x tier guarantees bonus entry, and 500x buys a Super Bonus with multiplier-Wilds active the whole time. Fog-covered gears and moonlit clockwork fill the background - darker and more mechanical than Cygnus 6, which leaned brighter. The paytable outside the pillar stays modest. Top symbol pays 1,000 coins at six-of-a-kind, and low symbols sit at 20, so the pillar multiplier is doing all the heavy lifting on any real payout.
