Bonus Round
Bonus Round is a special in-game stage, often triggered by scatters, that awards free spins, picks, or multipliers within a slot.
What it means in practice
Bonus Round refers to a special stage inside a slot game, usually triggered by landing scatters or a bonus feature, that rewards players with free spins, pick-style mini-games, or multipliers. It is one of the main moments players anticipate, which makes it a meaningful lever for engagement and retention.
For operators, the bonus round carries a disproportionate share of a slot payout, so it shapes how the configured slot RTP is distributed across a session. Many games hold back return-to-player in the base game and release it in the feature, which affects perceived volatility and how a title contributes to revenue. A scatter symbol is the most common trigger, and its frequency directly influences how often the round appears.
Bonus rounds also interact with marketing and promotions. Some titles offer a bonus buy to enter the feature instantly, and many operator promotions tie into feature wins, so terms such as a wagering requirement become relevant when bonus play converts to withdrawable balance.

Bonus Feature
Bonus Feature refers to any special slot mechanic beyond the base game, such as wilds, multipliers, free spins, or pick-bonuses.
Scatter Symbol
Scatter symbol is a slot symbol that pays or triggers a bonus or free spins regardless of its position on the reels.
Free Spins
Free spins are complimentary slot machine spins offered by online casinos as part of welcome bonuses, ongoing promotions, or loyalty rewards. They allow players to spin designated slot games without wagering their own funds, though winnings are typically subject to wagering requirements.
Bonus Buy
Bonus Buy is a slot option that lets a player pay a multiple of stake to trigger the bonus round instantly instead of waiting.
Slot RTP (Return to Player)
RTP (Return to Player) is the theoretical percentage of total wagered money that a slot machine or casino game is designed to pay back to players over time. An RTP of 96% means that, on average, the game returns $96 for every $100 wagered, with the remaining $4 representing the house edge.
Wagering Requirement
A multiplier condition that determines how many times a player must wager bonus funds before those funds become withdrawable. Wagering requirements directly affect operator bonus costs and affiliate RevShare earnings.
