How the Thor’s Hammer games differ
Bally Wulff’s Thor’s Hammer uses a 5×4 grid with a choice of 20 or 40 lines, wild symbols that multiply wins and free spins triggered by Mjolnir scatters. Hotdog Gaming’s online Thor’s Hammer uses a 5×3 grid, a Thor wild that multiplies the wins it is part of and a free games feature triggered by three or more hammer scatters. Wizard Games’ Thor’s Hammer Strike is a separate online release with its own rules.
Because the names overlap, the safest step is to open the help screens before you play. They show the maker, the paytable, the wild rules and what starts the free spins.
