Verdict

Matching symbols stack straight down a single reel here instead of spreading across a payline, which gives Rocket Fellas Inc's crystal-mine grid a different rhythm than most five-reel slots.

A fist marked BONUS turns up among the dwarves and gems too, the kind of symbol that keeps you watching one column rather than the whole board. It's an easy game to drop into for a handful of casual spins.

A run of target barrels lights up straight down the fourth reel here, which is how wins land in Rocket Fellas Inc — vertically, not across a line.

How it plays

Cartoon dwarves with big beards work a mine full of low-poly crystals here, and the reels stick close to that theme: red, gold and blue crystals sit alongside dwarf characters in several colours, plus a barrel-shaped target symbol that does most of the paying. Wins land vertically, with four matching symbols stacking down a single reel rather than spreading across a horizontal line, a different look from the usual left-to-right slot grid. A fist marked BONUS turns up among the crystals too. The layout runs five reels across four rows, and stakes in the demo run from 0.10 to 100.00 a spin.

Who it's for

Good for anyone curious about the vertical-match idea, or who wants a straightforward mining-and-crystals slot without a long list of mechanics to learn first. It's an easy one to try in a spare few minutes, whether or not the BONUS symbol shows up during that session.

Pros

Cons
