Casino games on apps: how each type plays on a phone
Casino apps in the UK carry far more than slots: card and table games, live dealer tables streamed from a studio, game shows built around a giant wheel, plus bingo, keno, scratchcards and instant-win games. Each type uses the touchscreen differently. A roulette app shows a betting layout you tap to place chips, a live blackjack table gives you a few seconds to choose hit or stand, and a game show asks you to back segments of a wheel before the host spins it.
Every game has a built-in advantage for the casino, shown as the house edge or the return to player in its help screen. Over many rounds that edge means the player is more likely to lose than win, so treat any game as entertainment with a cost.
| Game family | How you play on a phone | What sets the odds | Typical data use |
|---|---|---|---|
| RNG table games | Tap chips onto a digital layout, then deal or spin | Fixed rules, for example single-zero roulette has a 2.7% house edge | Low |
| Live dealer tables | Place bets on an overlay above a video stream | Same rules as the RNG version, plus any side bets | High, because of the video |
| Game shows | Back wheel segments or numbers before each round | Published RTP for each bet, often different per bet | High |
| Bingo, keno and instant wins | Buy tickets or cards, or reveal a scratchcard | Prize table and ticket price | Low to medium |
| Slot types | Spin reels in portrait or landscape | The game's RTP and volatility | Low |
How to use the game guides below
The cards are split into four groups: live casino and game shows, card and table games, slot types, and other games. Each guide explains the rules, the bets you can make, the published odds and house edge, how the mobile interface works in portrait and landscape, and which variants you are likely to meet. Where a game has a version with better rules, such as European rather than American roulette, the guide says so plainly.
For the most popular table games there are also full standalone pages: roulette apps, blackjack apps and live casino apps. If you are new, how casino app games work explains random number generators and RTP in everyday terms.

Choosing a casino game to play on your phone
Three questions narrow the choice quickly. First, how fast do you want the game to go? Slots and RNG tables run at a steady pace set by UK minimum round times, while a live table moves at the dealer's speed. Second, how much of the outcome rests on your decisions? Blackjack and video poker reward correct play, though no decision removes the house edge. Third, how much signal and battery do you have? Live streams eat both.
- Compare the house edge of similar games before you play; European roulette has one zero, which gives a lower edge than the American wheel.
- Read the rules screen for side bets, which usually carry a higher edge than the main wager.
- Try the age-verified demo version first where the app offers one, so you learn the buttons without staking money.
- Set a session budget before you open a live table, because rounds come round quickly.
UK rules for casino games in apps
Since 17 January 2025, online casino games other than slots in Great Britain must last at least 5 seconds per round and cannot offer autoplay or turbo features. Slots have been under similar rules since 31 October 2021, with at least 2.5 seconds per spin and no autoplay or slam-stop. Online slot stakes are capped at £5 a spin for adults aged 25 and over and £2 for those aged 18 to 24.
Your balance and net position must be visible while you play, and free-to-play demo games are open only after age verification. These rules apply identically in every licensed app; our UK slot design rules page explains the background and the reality check guide covers the session reminders you will see.
Live games, data and battery on mobile
Live dealer games stream video continuously, so they use much more mobile data and battery than RNG games, which download their graphics once and then exchange small amounts of data per round. If your signal drops mid-round at a live table, the game rules usually say that a confirmed bet stands and is settled whether or not you see the result, so check your history afterwards. Our explainer on how live casino streams work on mobile covers stream quality settings, and Wi-Fi or mobile data helps you decide which to use.
Frequently asked questions
Which casino game has the best odds in an app?
Blackjack played with correct basic strategy usually has the lowest house edge of the common games, often well under 1% depending on the table rules. Baccarat's banker bet and single-zero roulette also have relatively low edges. Every game still favours the casino over time, and side bets typically carry much higher edges. Check each game's help screen for the published figure, because rule variations change it. Our blackjack apps guide explains which rules matter most.
Can I play live casino games on mobile data?
Yes, but live dealer games stream video, so they use far more data than slots or digital table games. A long session on 4G or 5G can use a noticeable share of a monthly allowance, and a weak signal may cause the stream to freeze. Many apps let you lower the video quality from the table settings. If your connection drops, confirmed bets are normally still settled under the game rules. Our live casino apps page explains the settings to look for.
Why can I not use autoplay on casino games in the UK?
The Gambling Commission banned autoplay on online slots from 31 October 2021 and extended the ban to other online casino games from 17 January 2025. The Commission's stated aim was to slow play down and keep players actively choosing each round, giving them more control over time and spending. Turbo and quick-spin features were removed for the same reason, and minimum round times now apply. These rules apply to every licensed app and website. See UK casino app rules for the full list.
Are game show apps like Crazy Time worth playing?
They are entertaining but carry varied odds, because each segment or bet type has its own return to player. Game shows from studios such as Evolution publish an RTP for every bet in the help screen, and some bets return noticeably less than others. Rounds are also slower than slots, so sessions can last longer than you expect. Treat them as paid entertainment, set a budget first and compare the bets before choosing. Our Crazy Time app guide lists the bet types.
Can I play casino games for free in an app?
Some apps offer demo versions of games, but in Great Britain you must complete age verification before playing them, under rules in place since May 2019. That means registering an account even if you never deposit. Live dealer games almost never have a demo mode. A few apps also run free-to-play prize games for verified customers. Our guide to free slots apps explains how demo play works and what it can and cannot tell you about a game.
Do casino games play differently on an app than on a website?
The rules, odds and RTP of a game are the same whether you open it in an app or a browser, because both load the same game from the same provider. What can differ is layout: apps sometimes add quick access to recent games, biometric login and smoother transitions, while the browser may show slightly more of the table in landscape. Your balance and limits are shared. Our comparison of app versus mobile site covers the practical differences.
