Sooner or later you will buy “One Mind”, the grandmas will start whispering, and fleshy creatures will crawl onto your big cookie and begin eating your production. Your instinct will be to pop them immediately. That instinct is wrong, and this guide explains the maths.
What wrinklers actually do
A wrinkler attaches to your big cookie and eats a share of your CpS. Your visible cookie income drops. Nothing is destroyed, though — every cookie a wrinkler eats is stored inside it.
When you pop a wrinkler, it disgorges everything it swallowed, multiplied:
| Modifier | Multiplier on stored cookies |
|---|---|
| Base | ×1.1 |
| With Sacrificial rolling pins | ×1.05 on top |
| Shiny (rare golden) wrinkler | ×3 |
| Dragon Guts aura | +20% |
The base case is the important one: a wrinkler returns 110% of what it ate. Letting wrinklers feed is a straight 10% profit, and more with upgrades.
The cap: 14 wrinklers
The game limits you to 14 wrinklers at once. Once you are at the cap, no more spawn, and your CpS has stabilised at its reduced rate.
This creates the standard strategy:
- Trigger the Grandmapocalypse deliberately.
- Let all 14 wrinklers spawn and feed.
- Leave them alone for hours or days while you idle.
- Pop them all before ascending, or when you need a large cookie burst.
Your displayed CpS looks terrible the entire time. Your actual accumulated wealth is growing faster than if you had no wrinklers at all.
Shiny wrinklers
Occasionally a golden, shimmering wrinkler appears. It pays out three times the normal multiplier. There is also an achievement for popping one — and a separate one for letting them be.
If you are achievement hunting, note that some players deliberately keep a shiny wrinkler alive rather than popping it. Check which achievement you still need before you click.
When you should pop them
- Before ascending. Always. Stored cookies count as baked when released, so they contribute to your prestige. Ascending with fat wrinklers still attached throws that away.
- When you need a burst to afford a specific building or upgrade.
- Before a big combo, if you want a larger bank for a capped Lucky! payout.
When you should not
- Out of impatience because your CpS number looks low. That number is lying to you about your real income.
- Right after they spawn. They have eaten almost nothing; you get almost nothing.
Starting and stopping the Grandmapocalypse
The Grandmapocalypse advances through stages as you buy One Mind, Communal Brainsweep, Elder Pact and so on. Each stage makes grandmas stranger and wrath cookies more common.
You can pause it with Elder Pledge, which temporarily calms everything and removes wrinklers — note that this destroys them without payout in some versions, so pop first. Elder Covenant stops it permanently at the cost of a 5% CpS penalty.
Most players should not buy Elder Covenant. The wrinkler profit and access to Elder Frenzy (×666 CpS) outweigh a flat 5% loss by a wide margin.
The wrath cookie trade-off
During the Grandmapocalypse, some golden cookies become red wrath cookies. They can roll bad effects — Clot halves CpS for 66 seconds, Cursed Finger halts production for 10 seconds, Ruin eats part of your bank. But they are also the only source of Elder Frenzy (×666 for 6 seconds) and Devastation.
For anyone doing combo play, that trade is heavily in your favour. A ×666 window dwarfs the cost of an occasional Clot.
The summary
Wrinklers look like a punishment and are actually a savings account paying at least 10% interest. Let them eat, let them cap out at 14, and pop them all before you ascend. The only genuine mistake is clicking them the moment they appear.
Play Cookie Clicker and start your own Grandmapocalypse.
