CPS Checker

This site allows you to check if a macro breaks CPS rules as defined in the ILL rules document.
Note: just because a macro violates CPS rules, doesn't necessarily mean the level does.

ILL CPS Rules

The level must not include sections where clicks per second would exceed:

  • 15 clicks in a second.
  • 3 clicks in a frame.
  • A rate of 45 cps in any stint of 5 or more clicks.

This program checks if the above rules are satisfied for both players in a macro.

If they're not, it will tell you what frames the violations occur at.

An error occured while parsing the macro. Please make sure your macro follows the required format.

FPS: N/A

How each rule is calculated

Rule 1 is broken if:

  • There are more than 15 clicks between (frame of first click) and (frame of first click) + floor(fps).
Rule 2 is broken if:

  • There are more than 3 clicks on any given frame.
Rule 3 is broken if:

  • (Number of clicks in stint - 1) / [(frame of last click - frame of first click) / framerate] > 45.
