BetMGM Casino has compiled this slot glossary so bettors can begin with confidence.<\/span>\r\n

Slot Definitions for Frequently Used Terms<\/b><\/h2>"},{"acf_fc_layout":"large_image","image_options":"inline-image","image":68777,"image_link":"","caption_1":"","image_2":null,"caption_2":"","image_2_link":null},{"acf_fc_layout":"paragraph","title_only":true,"content":"When you <\/span>start playing slots<\/a><\/strong>, there\u2019s enough to learn with the various symbols, payout systems, and bonus mechanics potentially in play. If you\u2019re already knowledgeable about the most common slot terms, you can devote your attention to the more nuanced game elements on a greater level.<\/span>\r\n\r\nConfidence and knowledge won\u2019t <\/span>boost your slot odds<\/a><\/strong>, as these are games of pure chance, but understanding what each term means will help you to relax and have a good time. Here is a breakdown of the most common slot terms.<\/span>\r\n

Autoplay<\/b><\/h3>\r\nAutoplay slot settings<\/a><\/strong> give players the option to set a specific number of automatic spins at a certain bet value during their slot sessions, allowing them to just sit back and watch. For example, you might set the game to place 10 bets at $0.50 each, which will automatically play out without you needing to hit spin each time.<\/span>\r\n

Bankroll<\/b><\/h3>\r\nWhen bettors talk about <\/span>slot bankroll management<\/a><\/strong>, what they mean is managing the money they have to play casino games with during and between sessions. In this context, bankroll is simply a synonym for your gambling budget.<\/span>\r\n

Bonus<\/b><\/h3>\r\nThe exact meaning of this term can vary, as there are several <\/span>different types of casino bonuses<\/a><\/strong> as well as bonus features in slot games. Most of the time, though, a bonus refers to a result or feature that occurs less often in a given slot.<\/span>\r\n

Free Spin<\/b><\/h3>\r\nPeople who are lucky enough to <\/span>find free spins bonuses<\/a><\/strong> as they play slots get a designated number of plays without the need to risk any of their bankroll. Free spins can be a gameplay bonus or granted as part of a casino promotion.<\/span>\r\n

Hit Rate<\/b><\/h3>\r\nHit rate is the rate at which a particular slot awards a prize of any value. This is usually expressed as a fraction or a percentage, and accounts for all options in the game, including when placing <\/span>max bets<\/a><\/strong>.<\/span>\r\n

Payline<\/b>\u00a0<\/span><\/h3>\r\nSlot paylines<\/a><\/strong> are different patterns on the game grid that award a prize when the right combinations of symbols land on them. There are gameplay differences to consider in <\/span>single-line vs. multi-lines<\/a><\/strong> slots, as your wager can affect which lines become active in the latter.<\/span>\r\n

Paytable<\/b><\/h3>\r\nA paytable refers to any documentation with information about the slot\u2019s rules, the meaning of specific <\/span>slot bonus symbols<\/a><\/strong>, which bonus features are available, and the values of paylines. Bettors can also find specifics on hit rate and return to player in some slot paytables.<\/span>\r\n

Return to Player\u00a0<\/b><\/h3>\r\nReturn to player or <\/span>RTP in slots<\/a><\/strong> refers to the portion of all the money wagered on the game that\u2019s returned to players through winnings over a long period of time. It\u2019s expressed as a percentage. For example, if players on a slot game with an RTP of 96%, 96% of the wagers will be returned to players over an extended period. However, these returns aren\u2019t distributed evenly, as one player may get more money back than another.<\/span>\r\n

Scatter<\/b><\/h3>\r\nA scatter symbol is one that has a dedicated impact on gameplay regardless of where it lands on the reels. For example, in <\/span>classic slots<\/a><\/strong>, the scatter may appear as a BAR or a fruit symbol.<\/span>\r\n

Volatility<\/b><\/h3>\r\nSlot volatility<\/a><\/strong> reveals how much variance players can expect in results from one wager to the next. This is usually expressed as a rating system, using low, medium, and high distinctions.<\/span>\r\n

Wild<\/b><\/h3>\r\nIn many games, a certain symbol acts as the game\u2019s wild, meaning that it can \u201cfill in\u201d or substitute for other symbols to activate paylines and, in some cases, trigger <\/span>different slot features<\/a><\/strong>. Some wilds have special effects as well, such as expanding across reels or offering dedicated payouts.<\/span>\r\n

Meanings Behind More Rare Slot Terminology<\/b><\/h2>"},{"acf_fc_layout":"large_image","image_options":"inline-image","image":68779,"image_link":"","caption_1":"","image_2":null,"caption_2":"","image_2_link":null},{"acf_fc_layout":"paragraph","title_only":true,"content":"BetMGM slot games<\/a><\/strong> use many game mechanics and grant chances at special prizes. The rarer terms in this online slots guide<\/span> will assist players who want to dive deeper into understanding gameplay.<\/span>\r\n\r\nWhile exploring <\/span>how slots work<\/a><\/strong> will likely reveal these terms to you, you may also come across some of these during gameplay. It\u2019s good to have this glossary handy so you can refer to it quickly.<\/span>\r\n

Bonus Buy<\/b><\/h3>\r\nBonus Buy slots<\/a><\/strong> give bettors the choice to activate certain bonus features for an additional stake. Players should note that opting for the Bonus Buy typically doesn\u2019t usually improve their chances of winning any prizes compared to activating the feature without paying the extra stake.<\/span>\r\n

Expanding Symbols<\/b><\/h3>\r\nExpanding symbols are special symbols that grow in size on the reels when they appear. This effect emphasizes key elements of many <\/span>popular slot themes<\/a><\/strong>.<\/span>\r\n

Gamble Feature<\/b><\/h3>\r\nGamble feature slots<\/a><\/strong> ask players if they want to claim their winnings or risk their prizes for a chance at an even more valuable payout. Players need to evaluate these opportunities carefully.<\/span>\r\n

Progressive Jackpot<\/b><\/h3>\r\nProgressive jackpot slots<\/a><\/strong> dedicate a portion of each eligible wager to a jackpot prize pool that continues to grow in value until it hits a preset cap or a bettor claims the jackpot. The process begins anew after a player wins the prize.<\/span>\r\n

Reel Modifier<\/b><\/h3>\r\nReel modifiers change the layout, size, or structure of the reels to correspond with bonus features. Some slots with <\/span>cascading reels<\/a><\/strong> fit this description, as the reels change while the cascading effect is ongoing.<\/span>\r\n

Respins<\/b><\/h3>\r\nRespin slots<\/a><\/strong> are games that give players a kind of \u201csecond chance\u201d at winnings, as a secondary spin of the reels will follow the initial play after a wager is placed. In most cases, a particular symbol or combination of symbols is necessary to trigger the respin.<\/span>\r\n

Sticky Symbols<\/b><\/h3>\r\nSticky symbols are symbols that \u201cstick\u201d on the reels for multiple plays. <\/span>Sticky wild slots<\/a><\/strong> are the most common form of this mechanic.<\/span>\r\n
