ONLINE CASINO GAMES
A plain-English breakdown of every online casino game type — what each is, how the
house edge works, and where to find the best odds. OddsBully specialises in slots:
5,879+ titles with verified RTP and volatility data.
Online slot machines are the most popular casino game by player count and revenue.
They operate on a Random Number Generator (RNG), with each spin independent of the
last. The key stats are RTP (return to player — the percentage paid
back over infinite play) and volatility (how frequently and in what
size wins arrive).
House edge on slots ranges from 1% (99% RTP) to 8%+ (92% RTP) depending on the title
and operator. OddsBully tracks default RTP and volatility for 5,879+
published slots.
Blackjack
The lowest house-edge casino table game when played with correct basic strategy. House
edge: 0.5% (6-deck standard rules with correct strategy). Single-deck
blackjack can reach 0.15% with perfect play.
Unlike slots, blackjack's outcome is partially skill-dependent — basic strategy tables
are freely available and reduce the house edge to its mathematical minimum. Side bets
(insurance, perfect pairs) carry house edges of 5–15% and should be avoided.
Most casino bonuses either exclude blackjack from wagering or weight it at 5–10%.

Roulette
House edge depends entirely on wheel type: European roulette (single
zero) has a 2.7% house edge; American roulette (double zero) has a
5.26% edge — nearly double. Always choose European or French roulette when available.
French roulette with the La Partage rule (half your even-money bet returned when zero
lands) reduces the edge to 1.35% — the best roulette odds available.
Lightning Roulette and similar live variants introduce multipliers but raise the
effective house edge to 3–7%.
Live Casino
Live dealer games stream real croupiers dealing real cards or spinning real wheels via
HD video feed. Offered by Evolution Gaming, Pragmatic Play Live, and Playtech Live.
House edges mirror their RNG equivalents — live blackjack at 0.5%, live roulette at 2.7%.
Live games count toward casino wagering requirements at 5–20% weight on most bonuses —
or are excluded entirely. The social experience and real-time dealing are the draw;
the mathematical odds are identical to RNG equivalents.
Video Poker
Video poker offers the best house edges of any slot-adjacent game. Full-pay Deuces Wild
has a theoretical 100.76% RTP (player edge) with perfect strategy;
Jacks or Better full-pay returns 99.54%. These figures assume
perfect strategy play — error-prone players see significantly lower returns.
Most online casinos offer reduced-pay video poker (98–99% RTP), not full-pay versions.
Like blackjack, video poker is usually excluded or heavily restricted from bonus wagering.
