Game features
A game's feature is an operational rule, not merely a marketing word. Free spins award an additional number of resolved game rounds under defined conditions. Hold-and-respin mechanics typically keep specified symbols in place during repeated evaluations. Tumbles remove paying symbols and introduce replacements. These mechanisms can interact with multipliers, jackpot networks or changing symbol layouts, but they are not interchangeable.
A linked progressive pools defined contributions across connected machines or accounts under a particular approved scheme. By contrast, four separately listed prize levels are not automatically four progressive jackpots. Similarly, Megaways is a branded ways-to-win mechanic and does not describe the same combination counting as a fixed 25-line reel game.
Game formats matter too. IGT Cleopatra Keno is documented as keno in the manufacturer's material; it must not be sorted conceptually as a standard five-reel slot. A provider may offer multiple editions of the same game with different devices or permitted settings.
This section focuses on what the terms mean and how to read a paytable. Where the archived metadata does not include an authoritative game sheet, the feature assignment is treated as unverified. Nothing about a feature guarantees a win or removes the long-term statistical cost of gambling.
