Hammerstorm

Hammerstorm by Pragmatic Play drops players into a cartoony Norse world where Thor and his hammer guide you through a base game that stays quiet until Lightning symbols or Scatters crack things open. The real action lives in the Respin bonus, a Hold&Win-style round where Thor roams a growing grid — up to 7x6 with the Expand modifier active — collecting coins and lightning while three optional boosters keep things moving. It's a familiar format with enough twists to stay engaging, and with a max win of 10,000x on the table, the bonus round has plenty of upside.
