Cookie Clicker is a popular incremental game where your goal is to bake as many cookies as possible. The game is simple to learn but has a surprising amount of depth and strategy. Here's a step-by-step guide to get you started:

Step 1: The Basics - Clicking and Buying
Click the Big Cookie: When you first start, your only source of cookies is the large cookie in the center of the screen. Click it repeatedly to produce cookies.

Buy your first Cursor: As you accumulate cookies, you'll be able to buy your first building. The first one is the Cursor, which automatically clicks the big cookie for you. This is the foundation of your passive income.

Keep Clicking and Buying: Continue clicking the big cookie and buying more cursors. Once you have enough cursors, you'll start earning a whole cookie per second without any input.

Purchase Other Buildings: As you get more cookies, you'll unlock more buildings like Grandmas, Farms, Mines, and Factories. Each building has a different cost and production rate. A good strategy is to buy a few of each to see how they perform.

Look for Upgrades: Upgrades are a critical part of the game. They appear above your buildings and provide significant boosts to your cookie production. Upgrades can increase the efficiency of a single building, multiply your clicking power, or provide other bonuses.

Step 2: Golden Cookies and Strategy
Golden Cookies: Golden cookies are a random event that can appear on your screen. They provide a temporary but powerful bonus when clicked. These bonuses can include:

Frenzy: Multiplies your cookie production rate by a large factor (usually 7x) for a limited time.

Lucky: Gives you a significant amount of cookies, often based on your current CPS or bank.

Click Frenzy: Multiplies the number of cookies you get per click by a massive factor.

Timing is Key: As you progress, you'll want to strategize around golden cookies. Experienced players often try to get a "combo" by clicking a golden cookie to get a "Frenzy" and then clicking a "Click Frenzy" cookie while the first effect is still active. This can result in an enormous surge of cookies.

Prioritize Upgrades: Upgrades that enhance golden cookies (like increasing their spawn rate or duration) are incredibly valuable.

Step 3: The Mid-to-Late Game
The Grandmapocalypse: This is an event that you can trigger by purchasing certain upgrades related to grandmas. It can have both positive and negative effects on your game. It introduces "Wrath Cookies," which are the "dark" version of golden cookies and can either give you a boost or a negative effect.

Minigames: As you progress and accumulate "Sugar Lumps" (which are a separate resource that grows over time), you can unlock minigames for your buildings. These minigames provide new ways to gain cookies and upgrades. For example, the Temple minigame, Pantheon, allows you to equip different gods to receive various passive bonuses.

Ascension and Prestige: Eventually, your progress will slow down as upgrades become incredibly expensive. This is when you'll want to "ascend." Ascending resets your game, but you gain "prestige levels" and "Heavenly Chips."

Prestige Levels: These provide a permanent boost to your cookie production in all future playthroughs.

Heavenly Chips: These are used to buy "Heavenly Upgrades," which are powerful permanent upgrades that carry over between ascensions. It's recommended to ascend when you can afford some of the more important heavenly upgrades.

Achievements: Don't forget to keep an eye on your achievements! Gaining achievements gives you "milk," which provides a global boost to your cookie production.
