Verdict

The underworld setting carries this one on looks alone: stone tiles, glowing red frames, and a golden three-headed dog glaring out from the reels.

Chains and stone stairs fade into the smoke behind a straightforward five-by-three grid, built around plain matches rather than anything flashier on screen. Worth a look for anyone drawn to Thunderkick's darker series entries who wants the mythology dressed up properly.

How it plays

Cerberus and a glowing amphora watch over a run of stone-carved card values, the higher ones picked out with glowing red frames. A spiked Spartan helmet and a spiked mace sit among the symbols alongside the three-headed dog itself, all set against a red-and-purple underworld backdrop, with chains and stone stairs fading into the smoke behind the reels. The layout runs five reels by three rows, and what's on screen is built around straightforward matching rather than anything more elaborate. Wins line up across the grid the way the stone-carved card values are arranged, with the beast and the amphora doing the heavy lifting at the top of the paytable.
