Wolf Gold has two different bonus structures. Free spins combine the central reels into a giant symbol, whereas the Money Respin feature holds cash-valued symbols on the grid and resets its remaining respins when more land. A filled money grid has a separate award condition. These mechanics belong to the original Wolf Gold and should be checked separately from later games carrying the Wolf Gold name.

The library also explains the difference between lines, ways and clusters to help put these mechanics in context.
