How the game clock works
3-tick and 2-tick rhythm: the timing behind tick manipulation
Why tick manipulation in OSRS runs on a 3-tick or 2-tick cycle, what each beat asks of your clicks, and a rhythm trainer with a count-in to practise it.
Practise this: Tick Sense 5: Three-Step
Tick manipulation in Old School RuneScape makes a skilling action repeat on a short, fixed cycle, such as every 3 ticks or every 2 ticks, instead of at its normal pace. Whatever the method, the timing problem underneath is the same: one input, or one short sequence of inputs, has to land in the right 0.6-second window every 1.8 or 1.2 seconds, again and again, without drifting. This page is about that rhythm.
It does not list skilling methods. Each one has its own click sequence and the OSRS Wiki documents them well (Tick manipulation, OSRS Wiki). What follows is the part every method shares, explained tick by tick with Microgrind's timing model, plus a trainer with a count-in.
Why actions land on a cycle
The game only moves forward one tick at a time, every 600 ms (the game tick guide explains how). Anything that repeats therefore repeats a whole number of ticks apart. A 3-tick rhythm means the important input lands on ticks 0, 3, 6, 9 and so on; a 2-tick rhythm on ticks 0, 2, 4, 6. An input either makes a tick or waits for the next one, so there are no fractions of a tick. Methods with fractional names, such as the Wiki's 1.5-tick ones, describe an average over a longer whole-tick pattern.
The rhythm in numbers
At 600 ms per tick, the cycle lengths work out like this. The last column is the share of all time during which a click would land on a beat tick: the rest of the time, any click lands on a tick where nothing is due.
| Cycle | Length | Cycles per minute | Time inside an input window |
|---|---|---|---|
| 1 tick | 0.6 s | 100 | 100% |
| 2 ticks | 1.2 s | 50 | 50% |
| 3 ticks | 1.8 s | 33 | 33% |
| 4 ticks | 2.4 s | 25 | 25% |
| 5 ticks | 3.0 s | 20 | 20% |
So a 3-tick rhythm is 33 cycles a minute, and a 2-tick rhythm is 50: one beat every 1.8 or 1.2 seconds. Neither is fast as music goes. The difficulty is that each beat is only accepted inside one tick-long window, and that you have to keep it up for minutes.
How many actions a minute does each rhythm give?
| Cycle | One action every | Actions a minute | Actions an hour |
|---|---|---|---|
| 2 ticks | 1.2 s | 50 | 3,000 |
| 3 ticks | 1.8 s | 33.3 | 2,000 |
| 4 ticks | 2.4 s | 25 | 1,500 |
| 5 ticks | 3.0 s | 20 | 1,200 |
| 6 ticks | 3.6 s | 16.7 | 1,000 |
Each beat is one 600 ms window
An input is applied on the next tick after you make it, never the current one. So to act on beat tick T, the input has to be made during the 600 ms before T. On a 3-tick rhythm that leaves two windows in every three where a click does nothing useful:
On a 2-tick rhythm the windows alternate with dead ticks, which leaves much less room to recover from a slip:
The beat itself is the dangerous moment. A click made 40 ms after beat tick 5 does not count for it: it waits for tick 6, one tick late. The safe habit is the same as for any tick timing: click comfortably inside the window before the beat, not on the beat.
Counting the cycle
The simplest way to hold a short cycle is to count. For a 3-tick rhythm, count "one, two, three" on the ticks and act so that your input lands on "one". For a 2-tick rhythm, "one, two" works the same way. Two things make this easier:
- A count-in. A few audible beats before the first one you have to hit set the tempo in your head before it matters. Both rhythm levels and the trainer below start with one.
- Counting the dead ticks too. Counting only the beats ("one ... one ... one") drifts. Saying every tick keeps you on the grid, because each count is a fresh check against the clock.
| Level | Cycle | First beat | Metronome | Beats | Gold |
|---|---|---|---|---|---|
| Tick Sense 5: Three-Step | 3 ticks | tick 5 | Every beat | 20 | 1900+ points |
| Tick Sense 6: Inner Clock | 2 ticks | tick 5 | 4 count-in beats, then silence | 24 | 2280+ points |
When you slip: early, late and lost beats
Real rhythms wobble, so the rhythm levels judge each strike against your own previous strike, not against a fixed grid. A strike one tick early or late scores nothing but costs nothing, and the count restarts from where you actually struck. No strike within a tick of the beat is a miss, and the count carries on from where the beat should have been. A strike two or more ticks off the count costs 50 points. Medals ask for 95%, 80% and 60% of the maximum score.
Here is a scripted run through the 3-tick level (on the beat; on the beat; one tick late; on the beat; one tick early; on the beat; two ticks early, then on the beat; no strike; on the beat), graded by the drill itself:
| Beat due | Struck on | Graded | Points | Next beat due |
|---|---|---|---|---|
| tick 5 | tick 5 | on the beat | +100 | tick 8 |
| tick 8 | tick 8 | on the beat | +100 | tick 11 |
| tick 11 | tick 12 | late | 0 | tick 15 |
| tick 15 | tick 15 | on the beat | +100 | tick 18 |
| tick 18 | tick 17 | early | 0 | tick 20 |
| tick 20 | tick 20 | on the beat | +100 | tick 23 |
| tick 23 | tick 21 | off the count | −50 | tick 23 |
| tick 23 | tick 23 | on the beat | +100 | tick 26 |
| tick 26 | — | miss | 0 | tick 29 |
| tick 29 | tick 29 | on the beat | +100 | tick 32 |
Look at the "next beat due" column after the late and early strikes: the grid moves with you. That is deliberate. It means one slip costs you one beat, not the rest of the run, which is also what you want to learn: recover the rhythm from where your hands actually are, rather than trying to catch up.
Rhythm trainer
Pick a cycle and press start. Four count-in beats set the tempo; strike (click, tap or Space) so that your input lands on beat 5, then every cycle after your last strike. Every strike is graded by the same code as the rhythm levels. Turn the metronome or the windows off once the rhythm feels steady.
How to train it
- Tick Sense 5: Three-Step keeps the metronome on every beat. Get gold here first: it proves you can find the window every third tick.
- Tick Sense 6: Inner Clock halves the cycle and takes the clock away after the count-in. This is closer to doing it in the game, where you are watching the world, not a beat track.
- If either feels rushed, each level's practice aids can slow the tick to 0.9 or 1.2 seconds. Slowed runs do not count for the leaderboards, so step back up to 0.6 seconds once the count is automatic.
Quick answers
What does 3-ticking mean?
Repeating an action every 3 game ticks (1.8 seconds) by timing a set of inputs precisely; how each method does it is on the Wiki.
How long is a 2-tick cycle?
1.2 seconds, which is 50 cycles a minute. Each beat still has to land inside one 600 ms window.
Why do I keep drifting off the rhythm?
Two likely causes: counting beats rather than ticks, or clicking right on the beat, where a few milliseconds decide which tick you get. Count every tick and aim for the middle of the window.
