10 Casino Games with the Best Odds at 20Bet (Ranked)

Every casino game has a built-in house edge, which means the math is always slightly in the casino’s favor. What differs from one game to another is how large that edge is.

This article focuses on RTP (Return to Player) as the main way to compare games. RTP shows how much a game returns over time and gives the clearest picture of long-term odds. 20Bet displays RTP figures for most titles, which you can check by tapping the ‘i’ icon. 

Volatility (also called variance) describes how wins are distributed: low volatility means frequent small wins, while high volatility delivers rarer but larger payouts. 

Both factors matter: RTP for long-term value, volatility for session experience. The games below are chosen for their higher RTP values. 

Disclaimer: All RTP figures in this article are based on 20Bet’s game information panels and should be verified before playing, as values can vary by jurisdiction and may be updated by the casino.

Why Odds Matter: RTP, House Edge & Game Type

Odds shape your results long before you place a bet. RTP (Return to Player) shows how much of each wager a game is designed to return over the long run, calculated across millions of spins or rounds. It’s a theoretical figure, not a promise for short sessions, but it’s still the best baseline for comparing games.

House edge is the flip side of RTP — the casino’s mathematical advantage. Even small differences matter, because a lower house edge usually means your balance lasts longer over time.

Game type adds another layer. Table games like blackjack or baccarat mix RTP with player decisions, so skill can influence outcomes. Slots work differently: RTP defines long-term returns, while volatility controls how wins are distributed. High-RTP slots can still feel risky if volatility is high, delivering fewer but larger payouts.

Knowing this won’t change the math, but it helps you choose games more deliberately and play with better expectations.

Top Table Games (Best Odds)

If you like feeling in control, table games offer the best starting point. The five games below deliver RTPs from 97.0% to 99.2%, which are among the lowest house edges at 20Bet. For blackjack, optimal strategy maximizes these returns. For roulette, the math is fixed but transparent.

Aurora Blackjack Libra 

Blackjack has long been considered a thinking player’s game, and Aurora Blackjack Libra follows that logic. Under optimal play and depending on the ruleset, this title can offer RTP values around 99%, which significantly lowers the house edge compared to most casino games.

Key strategy tips for 20Bet casino games:

• Never take insurance (adds 7%+ to house edge, making it unprofitable)
• Double down on 11 vs dealer 2-10
• Always stand on hard 17+
• Use a basic strategy chart (widely available online or in-app)

Libra’s steady pace and clear rule display make it ideal for strategy implementation. Taking time to make correct decisions is more important than playing quickly.

Aurora Blackjack Taurus 

Aurora Blackjack Taurus from Evolution Gaming uses the same ruleset as Aurora Blackjack Libra, but runs at a faster table pace due to shorter betting windows and quicker dealer actions. The underlying game rules are identical, meaning the odds and RTP do not change with speed.

On 20Bet, both Aurora Blackjack Libra and Taurus are displayed with a 97.3% RTP, as shown in the game information panel. The difference between the two tables is tempo, not mathematics.

Aurora Blackjack is a multiplayer live-dealer game, streamed from a studio and shared by multiple players in real time. The faster rhythm in Taurus rewards players who already follow basic strategy, but does not alter expected returns.

Top Card by Winfinity 

Top Card by Winfinity is a RNG-based card prediction game built around a single choice: whether the next card drawn will be higher or lower than the current one. Each round is resolved immediately after the prediction, with no additional features or progression mechanics.

Payouts are determined by the probability of the selected outcome. Safer predictions offer lower returns, while less likely outcomes pay more. There is no player control over card distribution, and each round is independent, meaning odds reset every time.

According to Winfinity’s published game specifications, Top Card operates at approximately 97% theoretical RTP, calculated across all possible outcomes. This return reflects the game’s fixed probability structure rather than player decisions.

Immersive Roulette 

Roulette never really goes out of style, but Evolution Gaming’s Immersive Roulette makes it feel alive again. The game uses a European single-zero wheel, which delivers a 97.3% RTP on even-money bets such as red/black or odd/even.

This matters because the single-zero format offers a clear mathematical advantage over American double-zero roulette, where the extra green pocket reduces RTP to 94.74%. The resulting 2.56% RTP difference makes Immersive Roulette the stronger option over time for players who prefer a steady pace, simple decisions and transparent odds.

Lightning Roulette 

Developed by Evolution Gaming, Lightning Roulette follows European single-zero rules but adds a multiplier feature that changes how some wins are paid. Because of this mechanic, the game’s RTP is 97.3%, slightly lower than standard European roulette.

At the start of each round, 1 to 5 numbers are randomly selected and assigned Lightning multipliers ranging from 50x up to 500x. These multipliers apply only to straight-up bets placed on the chosen numbers. If the ball lands on one of them, the multiplier replaces the usual 35:1 payout. Even-money bets do not receive multipliers and are settled at normal odds.

This design keeps the core roulette structure intact while adding higher volatility to specific bets, making Lightning Roulette a clear option for players who want added intensity without losing the transparency of European rules.

Top Slot Games (Best Odds)

After the discipline of table games, slots feel like a different world — faster, louder, less predictable. All slot games run on RNG, meaning every spin is random and no player decision can influence the outcome.

That said, not all slots are equal in terms of long-term returns. Some titles are built with significantly higher RTP values, which affects the expected return over time. So if you’re switching from blackjack to the reels on 20Bet online, the games below stand out because each exceeds 98% RTP, matching or even beating the return levels found in many table games.

Gates of Olympus Super Scatter (96.5% RTP)

We start big. Gates of Olympus Super Scatter from Pragmatic Play is a high-volatility, RNG-based slot played on a 6×5 grid with a tumble mechanic, where winning symbols disappear and new ones fall in. Multipliers appear randomly during winning cascades and stack within a spin or free-spin round. Free spins trigger with four scatter symbols, during which multipliers occur more often.

Long non-winning streaks are common, so smaller bets suit it better. RTP for this title is casino-configured rather than fixed by the provider. At 20Bet, the game is currently displayed with a 96.5% RTP, as shown in the game’s information panel. Since some casinos may use lower RTP variants, this value should always be checked directly before playing.

Book of Knight Hold and Win 

Next comes balance. Book of Knight Hold and Win by BGaming is a mid-volatility, RNG-based slot built around frequent small returns rather than large swings, which helps keep balance movement smoother during longer sessions.

The Hold and Win feature triggers when six or more special symbols land, locking them in place and launching a set number of respins. New symbols reset the counter and add value until no further symbols appear. The feature triggers at random intervals, with no fixed spin frequency. RTP is configured by the casino. On 20Bet, the game is listed with a 97.8% RTP, visible in the information panel.

Elvis Frog TRUEWAYS 

Elvis Frog TRUEWAYS by Pragmatic Play looks wild but plays straight. On 20Bet, the game is displayed with a 96.3 % RTP and 262,144 win ways, as shown in the game interface. This configuration is consistent across the regions supported by 20Bet, with no lower regional RTP variants or altered feature settings. What you see in the game panel is the version in use, resulting in a lively slot that remains mathematically stable beneath its bright, noisy surface.

It’s a Joker (96.30% RTP)

A short break from the flashing lights. It’s a Joker from Felix Gaming is a low-volatility, RNG-based slot built around short cycles and smaller, more regular payouts rather than rare spikes. According to Felix Gaming’s official game information, the slot runs at a 96.3% RTP.

There is no fixed spin frequency for wins, but the low-volatility design means outcomes are more evenly distributed over time, rather than clustered into long dry runs followed by occasional large hits. This makes it a calmer option for players who prefer steady pacing over high variance.

Book of Flames Buy Bonus 

Book of Flames Buy Bonus by Novomatic is a Book-style slot that includes a Buy Bonus option, allowing direct access to the free spins feature instead of relying on random base-game triggers. On 20Bet, the game is displayed with a 96.7 % RTP, as shown in the game’s information panel.

Most of the return potential is concentrated in the free spins round, where expanding symbols and retriggers determine payouts. By shifting variance into a single, paid feature, the Buy Bonus format produces a more defined return profile than standard Book slots with long base-game cycles.
