An online casino may seem quite simple to the player. A player starts a game, chooses a stake, wagers the money and gets the outcome within seconds. But there are many other technical operations that have to take place in a certain sequence behind the short interaction.
The platform should confirm the player’s session, ensure that the player has a sufficient balance, interact with the game provider, log the bet, process the outcome and adjust the player’s account. It might also have to implement bonus rules, track out-of-the-ordinary activity and keep a thorough log of the transaction.
The platform needs to handle a massive amount of data traffic that does not slow player movements down when thousands of users are playing simultaneously or make it unreliable.
What is a Real Time Game Event?
A game event is an action or change that happens within a game while a player is using the platform. The start of a game is an event. There are many other events, such as submitting a wager, starting a round, receiving a result, and updating a balance.
Some events are set up by the player and others are provided by game providers or platform services. A temporary connection failure can generate an additional event, as can be a transaction rejection or a bonus being triggered.
Several events can occur in a single game round in just a few seconds. The platform should process them in the proper order and deal with similar action from numerous other players.
If the order is mixed the player can see a wrong balance or a round is not completed. A trustworthy event handling, therefore, is a basic part of the casino’s framework.
Preparing the platform for further finer-grained decomposition.Preparing the platform for further finer-grained decomposition.
The large casino platforms do not usually take care of each and every task by one large application. The platform, on the other hand, is segmented into smaller services that have specific responsibilities.
One service can handle player authentication and accounts. One could be for balances and finances. Other services provide for game sessions, bonuses, provider connections, reporting, fraud detection and customer notifications.
This allows the platform to be easily scaled and maintained. In the event that one component of the system becomes very loaded, more resources may be allocated to that service without affecting other services.
If a new game is released, for instance, there may be a sudden surge in game launches.If a new game is out, there could be a spike in the number of games launching. While the account registration and reporting systems remain unaffected, the service providing games can be expanded at the same time.
Having a division of responsibility also reduces the impact of technical issues. An analytical service does not have to be performed on time, or at all, to allow a player to open a game or to receive a completed result.
Using Queues and Streams to move events
If each platform communicates with every other platform component, this will be hard to manage quickly. Event queues and streams are used to organise the flow of information in casino systems.
The platform generates a report upon the submission of a wager telling what occurred. This message may include the player identifier, game identifier, round number, bet amount, currency, and current transaction status and time.
This information can then be used for processing by the services that need it. This is the wallet that stores the transaction of money. The activity is checked by the risk system. The event is stored in the reporting service for future analysis.
Queues are helpful when traffic surges. Quickly process reporting/notification work, but important financial events can still go through the platform.
This helps to avoid a sudden explosion of activity in all services at once.
Maintaining the responsiveness of the game.
Players look for instant responses with online games. Even if the underlying transaction is being processed, a platform can still seem unstable when it has long delays.
Traditional web sites typically follow a request/response pattern. Browser asks for information, server sends back information and connection closes. Live casino games might require continuous connectivity for new information to be presented as soon as it becomes available.
A WebSockets client is typically used to keep the connection between the player’s browser and the platform open. With this, the server can update the game states, countdowns, dealer actions and results without reloading the page.
For live casino games, it is especially vital that they have persistent connections. Players must be able to view playing cards, roulette and betting periods live. It can get messy when there are multiple players in the same round if you have to wait a few seconds for one player to finish.
Preventing Duplicate Transactions
Internet connectivity isn’t always reliable. It is possible for a player to lose their connection before they are told they’ve placed a wager. The device might then send the same request again.
If it’s not properly protected, the bet might be cashed twice.
Casino systems use unique round and transaction IDs to prevent this. The receiving service verifies to see if that identifier has already been mentioned before processing the request.
If the wager has already been accepted, the platform does not make another charge, but returns the status of the current transaction.
This is called idempotent behaviour. It makes sure that a repeat request doesn’t result in a redo financial action.
This is particularly significant for mobile players, as they can switch between wireless and cellular networks while gaming.
Protecting Player Balances
One player’s balance does not fit into the same category as any other information found on a website. If it takes another second for the game image to appear, the problem is only a nuisance, but it is not a big problem. The consequences are far more serious if a balance is incorrect.
Casino wallets thus employ comprehensive transaction histories. The platform is not just a balancing machine, it records the various debits, credits, reversals and adjustments.
Imagine that a player begins with $100, places a $5 wager and wins $12. The original balance, the total amount taken out of the account, the total amount returned in winnings and the final balance of $107 will all be recorded on the records.
This is a record of all transactions and how the balance has been amended. If the game provider reports an error later on the platform, they could put a correction into the game without removing the initial activity.
A full financial history allows the operator to look into any disputes and prove the processing of each result.
This is where you’ll find the best places to connect with multiple game providers.
Casino sites frequently have games from numerous game studios. Providers can have their own application programming interface, terminology, data structure and error messages.
A completed game may be “settled” by one provider and “finished” by another. The casino must use an integration layer that translates the various messages into a uniform internal format.
The layer lets the rest of the platform communicate with standard events, regardless of the studio who had created the game.
This also makes it easier to play the player. A platform like Miki casino in Ontario can handle a variety of titles, including slots and table games, as well as live casino games, all from different providers, in one single interface.
The system should maintain the original provider identifiers as well. Technical teams should be able to look at a result and find out where it came from (studio, game and round).
Employing different databases for different tasks
It’s hard to find one application that would work for every part of a big casino platform.
Consistency and vigilant safeguarding of account and financial information is essential. Fast search and filtering is needed in game catalogues. This information about the session needs to be obtained in a timely fashion, but not stored for a long-term period. Historical reporting systems can process millions of logs without impacting any ongoing games.
Therefore, a platform can store accounts and transactions in relational databases, and active sessions in memory, search indexes for game catalogues and analytical databases for historical reporting.
The separation ensures the player experience isn’t compromised. Several months of report of activity should not be the basis for a complex report that necessitates a balance update that must take place right away.
Scaling during busy times.
Casino traffic is not constant. Activity may be higher on evenings, weekends, when sporting events are held, game launches and on promotion days.
The platform can be scaled horizontally by running multiple instances of the same service. A load balancer spreads their work out between them so that each instance is not used exclusively.
It can track processing demand, response times, queue length, memory usage, number of active connections. If the demand increases then the number of service instances can be increased. In the event of return to normal activity, unessential resources can be eliminated.
During periods of low activity, automatic scaling keeps utilities under control without reducing responsiveness of the platform.
Keeping an eye on what is happening now.
It’s important for technical teams to find problems before they impact many people. Real time monitoring gives you information on the health of all of the important services.
Monitoring tools can also identify if a game provider is experiencing a lag in reply or if the wallet is experiencing delays in transactions or if error rates are increasing. They can also indicate if an entire event queue is becoming too fast or if players in a particular location are having connection problems.
Automated alerts alert the appropriate team to activity that falls outside of the expected range.
Distributed tracing offers even finer-grained information. It takes the form of a request as it goes through a number of services. When a game result is delayed, engineers can pinpoint the cause of the delay instead of going through unrelated information.
Conducting Security Inspections Without any Slowdowns
Security checks are important for online casino platforms to observe activity and detect dangers but should not delay legitimate users.
Automated systems can review device information, session activity, location data and transaction activity. They could see that a user has tried to log in multiple times, has changed their location, has multiple accounts on the same device, or is making unusual logins and withdrawals.
There are certain checks which occur before the approval of a transaction. The processing of the initial event can be parallelized and then the rest of the analysis can be continued.
The trick is to find the perfect balance. Security mechanisms need to be robust enough to monitor suspicious activity, but not interfere with normal play.
Dealing with technical failures and their consequences.
Distributed system failures are to be expected. The network may go down, the provider may have a maintenance period or an internal service may be temporarily unavailable.
Reliable platforms are built to address these issues in a safe and controlled manner.
An unsuccessful event may be tried again when it is safe to do so. If you repeatedly make requests that fail, they can be queued up separately for technical review. The platform will also not send requests to an unresponsive provider, temporarily, to prevent the issue from propagating to other services.
Most importantly, the overall financial status of every round should be apparent. The system should also be able to identify if the bet is accepted, rejected, settled or pending.
It must never make an assumption that a transaction that has a financial action has succeeded if there is no secure proof of the transaction.
It’s a simple experience in the guise of complex technology.It’s simple experience, but complex technology.
Thousands of game events aren’t just a question of having one powerful server. It needs a set of specialized services that can communicate reliably, and scales when demand increases.
Information flows through the platform with event streams. Duplicate transactions are avoided by unique identifiers. Detailed ledgers safeguard balance accuracy and monitoring systems aid engineers in the prompt identification of delays and failures.
This infrastructure will be seen by very few players. They just assume games open without a hitch, bets are accepted and their balances are updated without mistakes.
This is a simple experience that relies upon a complex real time system running all the time and in the background.
