Stop guessing. Start optimizing.
A bookmarklet that displays the most efficient purchase in Cookie Clicker using Cookie Monster's payback period calculations.
The Problem: Cookie Clicker has dozens of buildings and upgrades. Manually calculating which purchase gives the best return is tedious and error-prone.
The Solution: This bookmarklet analyzes all available purchases and tells you exactly what to buy next, with optional auto-purchasing.
| Feature | What It Does |
|---|---|
| Best Purchase Display | Shows the optimal item based on Payback Period (lower = better) |
| Auto-Purchase | Automatically buys the best item when you can afford it |
| Golden Cookie Handling | Auto-clicks golden/wrath cookies, prioritizes golden upgrades |
| Lucky Bank Protection | Reserves cookies for max Lucky rewards (phase-aware scaling) |
| Wrinkler Management | Tracks wrinkler rewards, suggests when to pop for faster progress |
- Open Cookie Clicker
- Click your bookmarklet
- A floating panel appears showing your best purchase
The optimizer uses Cookie Monster's Payback Period (PP) metric to rank purchases:
- Time to afford the item (if you don't have enough cookies)
- Time to pay for itself through increased CpS
- Synergies from achievements and bonuses
Lower PP = Better purchase

When enabled, automatically buys the best PP item as soon as affordable. Disabled by default.
When Gold: ON:
- Auto-clicks golden cookies instantly
- Auto-clicks reindeer during Christmas season
- Shows "Golden Priority" section for spawn-rate upgrades
- Prioritizes golden upgrades when combined with Auto
- Wrath toggle appears for red cookies
Test with: new Game.shimmer('golden') or new Game.shimmer('reindeer') in console
Reserves cookies for max Lucky + Frenzy rewards. Scales by game phase:
| Phase | CpS Range | Bank Protection | Golden Upgrade Priority |
|---|---|---|---|
| Early | < 1M | 0% (disabled) | Only if < 30 min |
| Mid | 1M - 100M | Scales 0% → 100% | Up to 4 hours |
| Late | > 100M | 100% (full) | Up to 12 hours |
Why? Lucky gives min(15% of bank, 900 × CpS). During Frenzy, you need 42,000 × base CpS banked for max reward.
During Grandmapocalypse:
- Shows wrinkler count and pop reward
- Highlights shiny wrinklers (3.3× reward, never auto-popped)
- Suggests when popping enables faster purchases
The optimizer recommends "One mind" to trigger Stage 1 Grandmapocalypse, which provides:
- Wrinklers (6× passive CpS multiplier)
- 67% Golden Cookies (only 33% Wrath Cookies)
This is the optimal balance for active players who click golden cookies.
The optimizer blocks Stage 2+ upgrades to prevent further progression:
- Communal brainsweep
- Arcane sugar
- Elder Pact
These would increase Wrath Cookie rate to 66-100%, disrupting golden cookie combos. If you want full Grandmapocalypse, purchase these manually.
The optimizer never recommends the Golden Switch. While it provides +50% passive CpS, it completely disables golden cookies. For active/semi-active play, golden cookie combos (Lucky + Frenzy) provide more value than the passive boost.

# Ensure you're on orteil.dashnet.org/cookieclicker/If you see "Timeout waiting for Cookie Monster":
- Refresh the Cookie Clicker page
- Wait for game to fully load
- Click bookmarklet again
- Check if Auto: ON is enabled (green)
- If Gold: ON, it may be saving for a golden upgrade
- Check Lucky Bank status - may be protecting cookie reserve
That's up to you. This tool automates decisions but doesn't hack the game. It uses the same calculations Cookie Monster provides - just with automation.
Cookie Monster has years of refinement on its PP calculations, accounting for synergies, achievements, and edge cases. Why reinvent the wheel?
Yes! By default, auto-purchase is OFF. The panel just shows recommendations - you decide when to buy.
No, this is for the web version only.
