Obsidian Rush XXL goes for pure retro sparkle. A huge faceted black diamond glows above the logo, heaps of white diamonds pile up beneath the grid, and red pinstripes race across the background. Its trio of reels each shows five rows inside a chrome frame. I spun at 0.10 with a 10,000 balance.
Theme and Gameplay
Familiar machine icons receive a polished finish: flaming blue sevens, a triple red seven, chrome horseshoes and red, gold and blue BAR blocks. Betting 0.10, you’ll see jackpots of Mini 1.5, Minor 3, Major 10 and Grand 100, equal to 15x, 30x, 100x and 1,000x the stake.
Slot Features
Coins only ever drop onto reels 1 and 3, while Collect icons belong to reel 2 alone. Each time it appears during regular play, it banks every coin value visible on the flanking reels, jackpots too, and pays them straight away.
Any coin or collector during a base spin can also trigger Gold Stack, which adds enough symbols to launch the Respins feature immediately. During respins the reel-2 collector stays fixed and keeps absorbing new coin values. Fresh coins or collectors restore all three respins, and whatever the collector has gathered pays out once nothing more lands. Standard Respins begin with one to five collectors; Obsidian Respins begin with three to five.
RTP and Win Potential
A Buy Bonus offers either respin round instantly, played exactly as a natural trigger. A 1,000x Grand and bonuses driven by collectors mean high volatility.
My Thoughts On This Slot
Obsidian Rush XXL is a slick update to the classic three-reel machine. Extra-tall reels give the collector more to work with, and Gold Stack adds a welcome surprise to ordinary spins.
Beyond the collect mechanic, variety is limited, and fans of longer feature rounds may want more.
