The tick is the fundamental quantum of time used in RuneScape, a length of 0.6 seconds. All actions are a multiple of this basic tick time. This includes any instant where a message appears in the chat interface, any instant that experience is gained, any instant that a monster spawns, and any other actions a player performs, including animations (hence players being able to perform animations in sync with each other rather easily). Purely client sided occurrences are independent of the game tick (e.g. right-click menus).
Each action you register within one tick, will start to take place by the beginning of the next tick.
However, Jmods on the Runescape Forum have explicitly said in the Engine Q&A threads in the past that some activities run as fast as 50ms ticks.
"Q. As we know and stated by Andrew the game runs at 600ms intervals (one tick). Is there a reason for this exact number? Could the game benefit from lower interval, for example 300ms?
A. Some upcoming features in the server tick at a 50ms rate. The overall 600ms tick remains, as the content relies on having this time interval available as a base, but we’re not limited by it.
Length of a tickEdit
The length of a tick can be measured by timing a repeated action using a stopwatch. For example, lighting 25 logs without re-lighting a log takes 100 ticks. If the stopwatch can be stopped to within 0.1 seconds, the tick can be measured to within 0.001 seconds. Another method is to use summoning familiars. Each "minute" that a familiar lasts for is actually 100 ticks. If, for example, you start a timer when a familiar timer goes from 26:00 to 25:30 and stop the timer when it goes from 16:00 to 15:30, this will be exactly 1000 game ticks.
Ideally, without any lag, there should be exactly 100 ticks per minute, or 0.600 seconds per tick. However, the observed length of the tick is actually slightly more than this, due to connection speed and the server having to process all the players that are currently logged in. The observed length of the tick is between 0.606 and 0.618 seconds. The tick length is constant throughout a server for all players, which is due to the fact that player's actions are processed in the same order every time, so even if someone is processed last, they will still have the same tick as previously due to them being processed last every time. However, the tick length is not constant from server to server. The more players there are on a server, the longer the tick length; the fewer players are on a server, the shorter the tick length. While there seem to be other factors that affect tick length as well, the number of players on the server seems to be the largest factor. It is typical for ticks on World 2 (usually a full world) to be 0.616 to 0.618 seconds each, whereas ticks on less full worlds typically are 0.606 to 0.611 seconds each.
It is possible for a server to lag and "miss" a tick or multiple ticks from time to time. This seems to happen most often on worlds with the greatest number of players.

With a rune pickaxe or inferno adze, there is a chance to mine an ore every 3 ticks.
This does not apply to rune essence, which comes more frequently than this, or to using a dragon pickaxe, which can mine ores at varying rates.
- POH Altar Offerings: 3 per bone
- Burying bones: 1 per bone (used to be 2)
- Ectofuntus: 1 per bonemeal+slime
Prayer activation and deactivation is applied on the next game tick, and the drain rate of each prayer is measured by a number of ticks.
At fastest, there are 6 ticks between crafts at the Nature altar if 2 or 3 pouches are emptied, or 5 ticks if 1 pouch is emptied. At fastest, there are 5 ticks between crafts at the Ourania altar if 2 or 3 pouches are emptied, or 4 ticks if 1 pouch is emptied.
- Smelting ores at a furnace: 4 per ore
- Forging at an anvil: 4 per item smithed
- Making Cannonballs: 10 per steel bar
- Blackjacking: 6 per round
- A Pyramid Plunder activity is 500 ticks.
- Chance of cutting a log from any type of tree: 4 per chance
However, you are not guaranteed a log every 4 ticks; rather, every 4 ticks there is a chance to cut a log.
- Running covers 2 squares per tick, while walking covers 1 square per tick.
- Bankers used to count down in ticks when there was a big drop in the falador party room. But as of the Free Trade return on 1 February 2011, they no longer do this.
- The amount of time a player can spend collecting tears in Tears of Guthix is a number of game ticks equal to the player's quest points.
- Boosted or reduced stats move towards normal at a rate of 1 level per 100 ticks, which is just a tiny bit over one minute.
- Player chat messages stay above their heads for 5 ticks. (exception: if a second message is sent sooner it will replace the first and last 5 ticks unless another message is sent sooner etc.)
- The 40 minutes of triple charms reward from Familiarisation seems to actually last around 40.5-41.5 minutes, which would suggest that it is measured as 4000 ticks rather than as 40 actual minutes.
- When playing Fist of Guthix, the person being hunted collects charges every 5 ticks when holding the stone.
