Elvis Presley: Cash is All Right

An Instant Prize Symbol is a special symbol whose role is to pay a set cash value or bet multiplier just by appearing on the reels. The core concept is that it provides a direct reward by its mere presence, without the need to form a winning line like regular symbols. It is often called a 'Coin' or 'Money Symbol' and serves as the most basic 'material' in various bonus features of modern slots.

A Symbol Modifier is a parent concept that encompasses all types of special symbols that go beyond simply having their own value or substituting for other symbols, to directly affect other symbols and change their value or state. These symbols act as 'commanders' that create variables in the bonus round and generate complex synergies between symbols.
