Prize Board is a feature where a special board displaying various rewards (instant prizes, jackpots, free spins, etc.) exists separately from the reel grid, usually at the top or side of the reels. The core of this feature is to provide a second, completely different winning opportunity apart from regular reel wins. Players simultaneously anticipate both the results on the reels and whether a good prize will appear on the prize board, as well as whether the 'trigger' combination to win it will land on the reels.

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.
