Know the Language, Own the Lobby

Knowing what a term actually means changes how you browse. When you understand volatility, you can choose between a high-cap game like Yellowstone Jackpot and a steadier session on Atlantic City Roulette without guessing. When you know what rollover means, you read a promotion clearly instead of being caught off guard. The same goes for payment terms — knowing the difference between

how a PayPal withdrawal clears versus a Play+ prepaid card reload affects how you plan your account balance. This glossary is here so the definitions are always one tap away, whether you're on mobile or desktop.

Core Casino Terms You'll See at Tombla

These are the terms that appear most often across our slot rooms, live dealer tables, and sportsbook markets. Each definition below is written for the way we actually use the term inside the lobby.

RTP is the percentage of total wagers a game is designed to return to players over time. We display it where the game provider makes it available — not every title exposes this figure.

House edge is the mathematical advantage the platform holds on any given game. A lower house edge means the game returns more to players on average over many rounds.

Volatility describes how a slot pays out — high volatility means bigger but less frequent wins; low volatility means smaller, more regular payouts. It shapes how your balance moves during a session.

A wager is the amount you place on a single bet or spin. Turnover refers to the total amount wagered over a period, often used to measure how much of a balance has been actively played through.

A jackpot is the highest prize a slot game can award. Some jackpots are fixed amounts; others accumulate as players bet. Prize-style slot features vary by title and provider.

A live dealer game streams a real human dealer from a studio to your screen in real time. You place bets through the interface while watching the dealer handle cards or a roulette wheel live.

Odds, Payment, and Account Terms Defined

These terms cover the sportsbook side, your account wallet, and the payment rails we support — PayPal, Venmo, and Play+. Understanding them helps you move money confidently and read betting markets correctly.

A point spread is a margin set by the sportsbook to level a matchup. You're betting whether a team wins by more or fewer points than that margin, not just who wins outright.

Over/under is a bet on whether a game's combined score will be above or below a number we set. It applies to NFL totals, NBA game scores, and MLB run lines, among others.

Rollover is the number of times you must wager a bonus amount before it becomes withdrawable. A 5x rollover on a $20 credit means $100 in total wagers before the amount clears.

An e-wallet is a digital payment account that holds funds separately from your bank. On tombla, PayPal and Venmo act as e-wallets, letting you fund your account without entering card numbers directly.

KYC is the identity verification process required before withdrawals are processed. You submit a government-issued ID and proof of address; this step protects your account and complies with platform security standards.

A same-game parlay combines multiple bets from a single game — for example, an NFL player prop and a point spread — into one wager. All legs must hit for the parlay to pay out.

How These Terms Apply Inside the Tombla Lobby

Definitions are one thing — knowing how they show up when you're actually navigating the lobby, placing a bet, or moving money is what makes them useful. These questions bridge the gap.

Tap the info icon on the game tile before you open it. RTP displays only when the provider has made it available — not every title in our catalogue exposes this number publicly.

High-volatility titles like Yellowstone Jackpot can run through a balance quickly before a larger hit lands. Setting a session budget before you start helps manage that stretch between payouts.

Once your KYC documents are approved, withdrawal requests to PayPal are processed to the same account used for deposits. Verification happens once; subsequent withdrawals follow the same path without re-submitting documents.

Yes — bets placed using your Play+ balance count toward rollover the same way any other funded wager does. Check the specific promotion terms in your account for any exceptions by game type.

Each leg of your parlay settles as the game's stats are confirmed. NFL player prop legs, for example, wait for official box scores. All legs must settle as wins for your parlay to pay out.

Canceling a pending withdrawal before it processes returns the amount to your account wallet balance immediately. From there you can re-wager it or submit a new withdrawal request through PayPal, Venmo, or Play+.
