The default tick speed in Minecraft is 20 ticks per second

A tick is one cycle of the game's internal clock. At the default speed, the game runs 20 of these cycles every second. This means the game updates the position of mobs, the growth of crops, the spread of fire, and every other moving or changing thing 20 times per second. If you have never changed this setting, your game is running at this default speed right now.

The tick speed matters because it controls how fast everything in your world happens. Slower tick speeds make the world move in slow motion. Faster tick speeds make everything move and change more quickly. Most players never need to change it — the default 20 ticks per second is what the game was built around, and it is the speed that feels normal when you play.

Key Takeaways

  • The default tick speed of 20 ticks per second means the game updates 20 times every second, controlling how fast mobs move, crops grow, and the world changes.
  • You can change tick speed using the command /gamerule randomTickSpeed in creative mode or on a server, but this only affects random events like plant growth, not the core game speed.
  • Lowering tick speed makes the world move in slow motion; raising it speeds everything up, but very high speeds can cause lag or break game mechanics.
  • The default 20 ticks per second is the speed Minecraft was designed for, and changing it is mainly useful for testing, building, or creating specific effects in custom maps.

How ticks control what happens in your world

Every tick, the game checks what needs to happen next. Mobs take a step, water flows, redstone circuits update, crops check whether they can grow, and the player's position gets registered. If you are standing still, the game still ticks 20 times per second — it is just confirming that nothing has changed.

Some things happen on a schedule tied to ticks. A crop in Minecraft grows when a random tick lands on it and certain conditions are met — the soil is hydrated, the light level is high enough. At 20 ticks per second, crops grow at a predictable rate. If you slow the tick speed to 10 ticks per second, crops take twice as long to grow because half as many random ticks land on them.

The difference between tick speed and frame rate

Tick speed and frame rate are not the same thing, and this confusion trips up a lot of players. Your frame rate is how many times per second your graphics card draws the screen — this is what you see in the FPS counter. Your tick speed is how many times per second the game's logic runs. You can have 60 FPS and 20 ticks per second at the same time.

A high frame rate makes the game look smooth. A high tick speed makes the game world move faster. You can have a smooth-looking slow-motion world, or a choppy-looking fast world, depending on which one you change. Most players care more about frame rate because it affects what they see on screen. Tick speed only matters if you are trying to speed up or slow down the world itself.

How to change tick speed if you need to

In single-player creative mode, you can change the random tick speed using the command /gamerule randomTickSpeed [number]. Type this into the chat window (press T to open chat). The number you enter replaces the default 3, which controls how many random ticks happen per block per second. This is different from the core 20 ticks per second — it only affects things like plant growth and block updates, not the overall game speed.

On a multiplayer server, the server owner can change the tick speed in the server.properties file by editing the line game-tick-rate=20. Changing this number changes the core tick speed for everyone on the server. A tick rate of 10 makes everything half as fast; a tick rate of 40 makes everything twice as fast. Very high tick rates (above 20) can cause lag because the server has to do more work every second.

In survival mode on a single-player world, you cannot change tick speed without turning on cheats first. Open the world to LAN (press Esc, then "Open to LAN"), turn on cheats, and then use the command above. Once you do this, achievements are disabled for that world.

Why you might want to change tick speed

Most players leave tick speed at the default because that is what the game is balanced for. Mobs deal the right amount of damage, crops grow at the right speed, and redstone circuits work as intended. But there are a few reasons someone might change it.

Builders sometimes slow down tick speed to make it easier to work on fast-moving things like water or lava. Creators of custom maps might speed up tick speed to make crops grow faster in a timed challenge. Server owners dealing with lag sometimes lower tick speed slightly to reduce the load on the server, though this makes everything in the world move more slowly. Testing redstone contraptions sometimes requires changing tick speed to see how they behave under different conditions.

What happens if tick speed gets too high or too low

If you raise tick speed very high — say, 100 ticks per second — the server has to do 5 times as much work every second. This usually causes lag, where the game stutters or freezes. Mobs move in jerky bursts instead of smoothly. Redstone circuits can break because they were not designed to update that fast. Players sometimes report that the game feels "wrong" at very high tick speeds because the physics and timing are off.

If you lower tick speed too much, the world moves in slow motion and becomes hard to play. A tick speed of 1 makes everything take 20 times as long. Crops barely grow, mobs move one block every second, and the game feels unresponsive. This is useful for testing or creating a specific effect, but not for regular play.

Frequently Asked Questions

Does changing tick speed affect my FPS?

Not directly. Tick speed and frame rate are separate. You can have high tick speed with low FPS, or low tick speed with high FPS. However, if you raise tick speed so high that the server or game engine cannot keep up, you may see lag, which looks like low FPS.

Will changing tick speed break my redstone contraptions?

Possibly. Redstone circuits are timed around the default 20 ticks per second. If you change tick speed significantly, circuits that rely on exact timing may not work the way they did. straightforward circuits usually survive, but complex ones often break.

Can I change tick speed on a realm or multiplayer server I do not own?

No. Only the server owner or someone with operator permissions can change tick speed. On a Realm, only the owner can change it. You can ask the owner to change it, but you cannot do it yourself.

What is the randomTickSpeed command actually changing?

The randomTickSpeed command controls how many random ticks happen per block per game tick. It does not change the core 20 ticks per second — it changes how often the game checks whether a crop should grow or a block should update. The default is 3, meaning 3 random ticks per block per tick.
