Notes: 17,359 lines, unminified; every locator is a line in this exact file. main.js holds no version string of its own: the version comes from the page that loads it (index.html line 6, `var VERSION=2.058;`, which loads `main.js?v=13g`). index.html isn't hashed because Cloudflare injects a per-request token into it. The server's Last-Modified (Tue, 13 Jan 2026 21:30:07 GMT) matches the newest changelog entry (“01/13/2026 - housekeeping”, L1451). The Wayback captures of 2026-06-16 and 2026-07-06 decompress to this exact file (same sha256). Local copy: .cache/files/cookie-clicker/main.js.

Claims (23)

One global constant, `Game.priceIncrease` = 1.15, multiplies a building's price for each one already owned.	`main.js L7972`	T4
A building's next price is $⌈ basePrice \times {1.15}^{\max (0, owned - free)} ⌉$ , with discounts applied before rounding.	`main.js L8090–8095`	T4
Free buildings (Starter kit: 10 Cursors; Starter kitchen: 5 Grandmas) come off the exponent, so the next one costs the base price.	`main.js L8266–8275main.js L3828–3829`	T4
Every building after the Cursor gets its base price from one formula on its index $n$ : $(n + 9 + 5 \max {(0, n - 5)}^{1.75}) \times 10^{n} \times \max (1, n - 14)$ , rounded to two significant figures.	`main.js L8024–8031`	T4
Only the Cursor keeps its `Game.Object` constructor price; the formula overwrites the rest (the Farm's 500 becomes 1,100).	`main.js L8003–8034main.js L9104`	T4
Base prices (the first one's price) are Cursor 15, Grandma 100, Farm 1,100, Mine 12,000, Factory 130,000, Bank 1.4 million, and so on up to You at 5.4 × 10²⁶.	`main.js L8979main.js L8024–8031`	T4
Base production before upgrades is 0.1 cookies/s for the Cursor, set in its own production function, and $⌈ 10 \cdot n^{n / 2 + 2} ⌉ / 10$ to two significant figures for building $n$ : Grandma 1, Farm 8, Mine 47, Factory 260, and so on up to You at 5.1 × 10¹⁴.	`main.js L8018–8022main.js L9104–9109main.js L9001main.js L8912–8916`	T4
Each type's production is `amount * storedCps`, summed into cookies per second, so before upgrades income grows linearly with count.	`main.js L5276–5285`	T3
On Grandma income alone, the wait for the next Grandma is 115 s for the 2nd, a low of 38 s for the 8th, and 36 minutes for the 51st.	`main.js L8090–8095main.js L5276–5285`	T4
The shown bulk price (`getSumPrice`) is the geometric sum $b \cdot r^{a} \cdot (r^{k} - 1) / (r - 1)$ , discounted and rounded up once: 20.30× the next single price for 10, and 7.83 million× for 100.	`main.js L8096–8105`	T4
Bulk options are 1, 10, and 100; “All” works only in sell mode and means 100 in buy mode.	`main.js L8816–8825`	T3
`buy()` charges each unit's rounded-up price in turn and ignores the shown total: 10 Grandmas from zero cost 2,035, not 2,031, and 2,030 cookies still buy 9.	`main.js L8125–8152main.js L8898–8901`	T4
Each sale pays 25% of the next one's price, rounded down, about 15% more than the label: selling 1 of 10 Grandmas shows 88 and pays 101.	`main.js L8156–8176main.js L8106–8123main.js L1620–1628`	T4
Discounts from upgrades, auras, buffs, and gods multiply the price by constants such as 0.99 or 0.95, lowering the curve without changing its 1.15 slope.	`main.js L8792–8814`	T3
The changelog dates the launch to 8 August 2013; Orteil says he made the original “in a couple hours, for laughs”.	`main.js L2020–2021`	T2
The changelog's 24 August 2013 “big update!”, which “revamped the whole game (new graphics, new game mechanics)”, falls between the 1.1 and 1.15 captures.	`main.js L2014–2015`	T2
The 25 August 2014 “legacy beta, part I” notes say “price and CpS curves revamped”.	`main.js L1790–1792`	T2
The game's About text credits it as “a javascript game by Orteil and Opti”.	`main.js L1410`	T2
The changelog's 1 September 2021 entry announces the Steam release and says web and Steam will get the same updates.	`main.js L1505–1507`	T2
The changelog's 28 September 2019 entry announces the official Android version, with iOS to follow.	`main.js L1553–1559`	T2
A price that grows by a factor of $r$ per purchase doubles every $\ln 2 / \ln r$ purchases.	`main.js L7972`	T4
With income linear in the count, waits shrink until $n = 1 / (r - 1)$ owned, then each is about $r$ times the last.	`main.js L5276–5285main.js L7972`	T4
A long bulk purchase whose price grows by a factor of $r$ per item costs about $r / (r - 1)$ times its last price.	`main.js L8096–8105`	T4
