Video Slot games have a more varied range of special features than you would find in a Classic Slot game. The exact features found on each game are described on that game’s Pay Table Screen. Instructions for each game are also given on-screen when a feature game is triggered.
Feature Games. Each feature game tends to be unique to a specific Video Slot game. It will be triggered either by the presence of one or more particular symbols (which might or might not provide a payout in their own right), or some other pre-defined conditions that occur during the game. The feature game will typically take place on a totally different screen, and give you the chance to either increase your existing winnings, or to win a bonus, independent of any credits that you may already have won. The exact features offered by each game will be described on that game’s Pay Table screen, as well as being described on-screen when the feature game is launched.
Gamble. The Gamble option is a feature that exists on certain games, which, when you win a payout, allows you to choose to gamble that payout in order to increase it (although as it is a gamble, you may also lose it).
Scatter. Most Video Slot games have a designated Scatter symbol, which can have a range of special features if encountered during a game. As with most features, the exact effect of Scatter symbols varies from game to game, but they do have some things in common.
Scatter symbols are an exception to the Wins Pay Left to Right rule, and are counted as a win no matter which reel they are on, or which payline. Some games will even count them if they appear on an inactive payline.
Scatter symbols will often win a number of free spins, the number of which depends on the number of scatter symbols showing.
In some games, scatter symbols will also win a payout in the same way as normal symbols, and might offer a bones on wins that happen on one of the free spins. In other games, scatter symbols only win free spins, with no payout or additional bonuses.
Bonus. In games that have an extra bonus symbol, in addition to Scatter and Wild symbols, a set number of these symbols occurring will trigger a bonus feature game. Usually, bonus symbols are an exception to the Wins Pay Left to Right rule, and will count as long as they appear on any of the active paylines.
Wild. Wild symbols can be substituted for any other symbol (not including Scatter and Bonus symbols) to complete a winning combination. Some games offer a bonus for a winning combination that includes a wild symbol.
Note: A winning payline containing wild symbols will always be valued as the highest possible valid combination, even if that means that they are substituted for a symbol that does not appear on the winning payline.
E.g. If A is the most valuable symbol in the game, and 3xA is worth more than 4xJ, then the wild symbols (W) in W-W-W-J-K would be read as A-A-A-J-K, instead of J-J-J-J-K.
Progressive Jackpot. Some games have a progressive feature: a jackpot that accumulates over time, the more the game is played. This jackpot is separate from normal payline wins, and is won in conditions that are unique to the particular game. In some games, the Progressive Jackpot can be won during the main game, and in others, it could be the prize for winning a feature game.
