A **pick and click bonus** is a slot feature that lets you select hidden items on the screen to reveal prizes, free spins, multipliers, or other bonus awards. You’ll see it in many online and land-based video slots as a more interactive bonus round, but it still runs on the game’s RNG rather than player skill.
If you’ve read a slot review or opened a modern jackpot-style game, you’ve probably seen the term **hold and spin**. It refers to one of the most common slot bonus mechanics today: special symbols lock in place, the game gives you a few respins, and each new symbol can extend the feature. Understanding it helps you read paytables, compare bonus potential, and avoid confusing this mechanic with similar labels like Hold & Win or Lock and Respin.
If you see a slot review mention a **respin feature**, it means the game can award one or more extra reel actions after a qualifying result. In some slots, a single reel spins again to complete a payline; in others, bonus symbols lock in place while the remaining positions respin until the feature ends. Understanding the respin feature helps you read paytables correctly, compare volatility, and avoid confusing it with free spins or tumbling reels.
A **free spins feature** is one of the most common bonus mechanics in slot games, but it is often misunderstood. In simple terms, it gives you a set number of spins inside the game without deducting a new wager for each of those spins, usually after a special trigger such as scatter symbols. Understanding how it works helps when reading slot reviews, comparing volatility, and separating an in-game bonus feature from promotional “free spins” offered by a casino.
In slot games, a **bonus buy** lets you skip the wait and pay to enter the bonus round immediately. It is a popular feature in online slot reviews because it changes session pace, volatility, and bankroll risk in a very obvious way. If you see bonus buy on a game menu, it usually means you can purchase direct access to free spins or another bonus feature, but not a guaranteed win.
A **bonus round** is one of the most important slot terms to understand because it often explains where a game’s biggest swings, special mechanics, and signature moments come from. In both online and land-based slots, the bonus round usually refers to a triggered feature that changes the normal rules and gives extra ways to win. If you read slot reviews, compare volatility, or want to know what a game’s “feature” actually does, this is the term to know.
The **base game** is the standard version of a slot that runs on ordinary paid spins, outside of separate bonus rounds. It is the part of the game players experience most often, so it has a huge effect on how a slot feels, how long sessions last, and whether the game seems engaging between features. If you understand the base game, you can read a slot far better than by looking at the bonus screen alone.
A **long cycle slot** is usually a player shorthand for a game that can stay quiet for long stretches before a bonus round or meaningful payout appears. The term is common in slot talk, but it is often misunderstood: it describes payout distribution and volatility more than any fixed schedule. If you play slots in a casino or online, knowing what it really means can help you choose a game style without assuming a machine is ever “due.”
Hit frequency is one of the most misunderstood slot-math terms. It tells you how often a slot produces some kind of winning event, but it does not tell you whether the game is generous overall. To judge a slot properly, you need to read hit frequency alongside RTP, volatility, and the size of typical wins.
A low volatility slot is built to produce smaller, more frequent wins and gentler bankroll swings than high-volatility games. That does **not** mean it offers a better overall return, because RTP and volatility measure different parts of slot math. If you want to compare games properly, understand session risk, or read slot reviews without confusion, this distinction matters.
