How to Use the Open Sesame in Cookie Clicker?
The Open Sesame heavenly upgrade in Cookie Clicker is a powerful tool that allows players to permanently boost their building production based on the number of achievements they’ve unlocked. This article will guide you through understanding and maximizing its benefits.
Understanding the Open Sesame
Cookie Clicker, the deceptively simple yet endlessly engaging idle game, rewards player progression through various means. One of the most significant is the Heavenly Chip system, unlocked upon the first ascension. These chips are spent on persistent upgrades that enhance subsequent playthroughs. Open Sesame is one such upgrade, drastically increasing the efficiency of early-game buildings.
Benefits of Acquiring Open Sesame
Open Sesame provides a direct boost to building production, but it’s the method of that boost that makes it so valuable. Rather than offering a flat percentage increase, it scales with your achievement count. This means the more you explore and complete the game’s many challenges, the stronger Open Sesame becomes. The key advantages are:
- Early-Game Acceleration: Reduces the early-game grind, allowing you to reach higher production levels faster.
- Achievement Synergy: Encourages you to actively pursue achievements, indirectly boosting your overall gameplay experience.
- Persistent Power: The effect carries over between ascensions, making each subsequent playthrough significantly easier.
How Open Sesame Works: A Detailed Look
The Open Sesame upgrade increases the base production of all buildings based on your achievement count. Specifically, the formula is:
Production Multiplier = 1 + (Achievement Count / 100)
This means for every 100 achievements you have unlocked, your building production will be doubled. For instance, with 300 achievements, your buildings will produce four times their base amount.
Acquiring Open Sesame: The Purchase Process
The Open Sesame upgrade can be purchased in the Heavenly Upgrade screen after ascending. Here’s the process:
- Ascend: Reach a point in your current playthrough where you can reasonably gain a decent number of Heavenly Chips by ascending. Usually, this happens after achieving a large number of prestige levels.
- Navigate to the Heavenly Upgrade Screen: After ascending, click the “Legacy” button, then the “Upgrade” button.
- Locate Open Sesame: Find the Open Sesame upgrade within the list of available upgrades.
- Purchase: Ensure you have enough Heavenly Chips and click the upgrade to purchase it. It costs 20 Heavenly Chips.
- Start a New Run: Begin a new run, and the effects of Open Sesame will be immediately active.
Optimizing Your Achievement Count for Maximum Impact
The effectiveness of Open Sesame is directly tied to your achievement count. Here are some tips for maximizing your achievements:
- Systematically Complete Achievements: Actively look for achievements you haven’t unlocked yet and tailor your gameplay to achieve them.
- Use the Cookie Clicker Wiki: The wiki is a valuable resource for finding specific requirements for each achievement.
- Consider Achievement-Hunting Runs: Dedicate specific runs to focus solely on unlocking as many achievements as possible. This might involve using specific strategies or save-scumming.
Common Mistakes to Avoid
- Ignoring Achievements: Some players focus solely on raw cookie production and neglect achievements, missing out on the benefits of Open Sesame.
- Ascending Too Early: Ascending before unlocking a substantial number of achievements can limit the initial impact of Open Sesame.
- Underestimating its Power: The scaling effect of Open Sesame makes it more powerful than many other flat-percentage upgrades, especially in the long run.
Example Scenario: Boosting Your Cookie Empire
Let’s say you have 250 achievements unlocked when you purchase Open Sesame. This means your building production will be multiplied by 1 + (250/100) = 3.5. This translates to a 350% increase in the base production of all your buildings, significantly accelerating your progress.
Troubleshooting and FAQ: Common Issues
Sometimes things don’t go as planned. A common issue is players expecting an immediate dramatic change after purchasing Open Sesame. Remember, the effect is proportional to your achievement count, so the impact will vary. Also, ensure you have actually purchased the upgrade in the Heavenly Upgrade screen after ascending.

Frequently Asked Questions (FAQs)
H4: What exactly does “base production” mean?
The base production is the default cookie output of each building before any multipliers are applied. Open Sesame directly boosts this base value, making subsequent multipliers even more potent. Think of it as the foundation upon which your cookie empire is built.
H4: Does Open Sesame affect Grandmas?
Yes! Open Sesame affects all buildings, including Grandmas. This makes it an especially valuable upgrade in the early game, as Grandmas are a very efficient early-game building.
H4: How does Open Sesame compare to other Heavenly Upgrades?
Open Sesame scales with achievements, making it unique. Many other upgrades provide flat percentage increases. While those might seem better initially, Open Sesame will often surpass them as your achievement count grows.
H4: Is Open Sesame worth buying early in a legacy?
Absolutely. It only costs 20 Heavenly Chips, and even with a moderate number of achievements (e.g., 100-200), it provides a significant production boost. It’s considered a core upgrade to purchase early.
H4: Can the achievement bonus of Open Sesame reach infinity?
While theoretically possible, there’s a soft cap on the practical benefit. Once you’ve unlocked a vast majority of achievements, the marginal benefit of each additional one diminishes. However, it can still become extremely powerful.
H4: Does Open Sesame affect Golden Cookie clicks?
No. Open Sesame only affects the base production of buildings. Golden Cookies and their associated effects are calculated separately. However, a higher base production will indirectly lead to more cookies during Golden Cookie buffs like “Cookie Chain.”
H4: What are the most efficient buildings to buy with Open Sesame active?
The most efficient buildings depend on the specific point in the game. In the early game, Grandmas are usually a good choice. As you progress, aim for buildings with high CPS (Cookies Per Second) that also have synergistic upgrades.
H4: How can I see the exact bonus Open Sesame is providing?
Unfortunately, there’s no direct in-game display of the Open Sesame bonus. You need to manually calculate it using the formula: 1 + (Achievement Count / 100).
H4: Does Open Sesame stack with other building production bonuses?
Yes! Open Sesame stacks multiplicatively with other building production bonuses, such as those from upgrades, cookies, and buffs. This is what makes it so effective.
H4: Can I “save scum” to get better results with Open Sesame?
While save-scumming (loading a previous save) can be used to influence certain random events, it does not affect the Open Sesame bonus, as that is determined solely by your achievement count at the time of purchase.
H4: Is there a limit to how many times I can purchase Open Sesame?
No. You only need to purchase it once per legacy (after ascending). Its effect is persistent across playthroughs within that legacy.
H4: Does the Lucky! achievement affect Open Sesame?
No. While both involve achievements, the Lucky! achievement directly increases the chance of getting Lucky cookies from Golden Cookies. Open Sesame, on the other hand, is a heavenly upgrade that boosts building production based on the total number of achievements you’ve unlocked. They are entirely separate systems.
