- Aggregator
- A B2B platform that connects many game studios to many casino operators through one integration, so operators can add large catalogues without integrating each studio separately.
- Agent ID
- An identifier issued by a game provider to each operator site or brand during onboarding. Every API request from that site carries its agent ID.
- B2B game provider
- A company that develops casino games and licenses them to operators and aggregators instead of offering them to players directly. 3i Studio is a B2B game provider.
- Bingo
- A number game where players mark numbers on a card as they are drawn and win by completing a pattern. Online bingo can be multiplayer or single-player.
- Bonus buy
- A slot feature that lets a player pay a fixed price to go straight to the bonus round. It is restricted or banned in some markets.
- cancelBet (rollback)
- A seamless-wallet call that reverses a bet when the game provider did not receive a confirmed response, so the player’s balance stays correct.
- Cascading reels
- A slot mechanic where winning symbols disappear and new symbols fall into place, allowing several wins from one spin. Also called tumbling or avalanche reels.
- Crash game
- A game where a multiplier rises from 1x until it “crashes” at a random point. Players must cash out before the crash to win.
- Free spins
- Bonus spins awarded by a slot feature, usually triggered by scatter symbols, that do not cost the player a new stake.
- Game certification
- Independent testing of a game’s random number generator and mathematics by an accredited lab, such as GLI, BMM Testlabs or iTech Labs, against a market’s technical rules.
- Hit frequency
- How often a game pays any win, shown as a percentage or as “1 in X” spins.
- Keno
- A lottery-style game where players pick numbers, the game draws numbers at random, and payouts depend on how many picks match.
- Launch URL
- A single-use web address returned by the game provider that opens a game for an authenticated player session.
- Max win
- The largest amount a game can pay on one round, shown as a multiple of the stake, for example 5,000x.
- Operator
- A company that runs a casino or gaming platform and offers games to players, such as an online casino, sportsbook or sweepstakes site.
- Paylines
- The lines across a slot’s reels on which matching symbols create a win. Games without paylines use “ways to win” or cluster pays.
- Plinko
- A game where a ball drops through rows of pegs and lands in a slot at the bottom, each slot paying a different multiplier.
- Remote game server (RGS)
- The back-end system that runs casino games: it holds game logic and the random number generator, decides every result, manages sessions and talks to the operator’s wallet.
- Responsible gaming
- Policies and tools that help players stay in control, such as deposit limits, session reminders, time-outs and self-exclusion.
- RNG (random number generator)
- Software that produces unpredictable results for each game round. Certified RNGs are tested to show that outcomes are random and fair.
- RTP (return to player)
- The share of all money wagered on a game that it pays back to players over a very large number of rounds. A 96% RTP returns 96 for every 100 wagered in the long run.
- Sandbox
- A test environment where an operator integrates and tests a game provider’s API with test credentials before receiving production access.
- Seamless wallet
- An integration model where the player’s balance stays in the operator’s wallet and the game provider calls the operator in real time to authenticate, debit bets and credit wins.
- Sweepstakes casino
- A social casino, common in the United States, that uses two virtual currencies: Gold Coins for fun play and Sweeps Coins that can be redeemed for prizes under sweepstakes rules.
- Sweeps Coins (SC)
- The promotional currency on sweepstakes casinos that can be redeemed for prizes. 3i Studio game sheets list bet ranges in SC.
- Transfer wallet
- An integration model where players move money from the operator’s wallet into a separate game-provider wallet before playing. Less common than seamless wallet.
- Volatility
- How a game’s wins are distributed. Low-volatility games pay small wins often; high-volatility games pay less often but with bigger wins.
