What Is a Slot?


A Slot is a limit on the number of aircraft that can be taken off or landed at a certain airport during a given time. It is distinct from air traffic control clearance or similar authorizations and can be used to manage congestion.

Different environments for different purposes

Deploying to a slot instead of directly to production allows the app to warm up before going live, which reduces latency for HTTP-triggered workloads. Using slots also makes it easier to swap to production and back with easy fallbacks.

Name consistency among settings

When you create deployment settings in one slot, make sure that you define the same values in any other slots involved in a swap. This helps ensure that your code doesn’t try to access a setting with the wrong value in the new slot.


A slot has a pay table that tells you the amount of credits you’ll win if you get specific symbols on an active payline. These symbols can be a combination of symbols that are part of a winning line or wild symbols, which substitute for other symbols to form a winning combination.


Generally, low variance slots pay smaller wins more often than high variance slots. This may not make a big difference in the overall RTP, but it does increase your enjoyment by reducing the number of times you don’t hit the jackpot.

There are many different types of slot machines, so it’s important to choose the ones you like best. Whether you prefer simpler machines with a single payout line or more complex ones with multiple payout lines and bonus features, it’s important to play the ones that fit your style of gameplay.
