How many achievements are there, and which requirements are public?

Steps

1. Use the public progression achievements first: QWACK!, KACHING!, FIESTA! and WEIRD! mark the four product unlocks.
2. Track the public combo targets MORE! x100, EXTRA! x200 and MEGA! x300.
3. Track the public volume targets MESS! 500 loose, LAG! 1,000 loose and STUFFED! 15,000 fed.
4. Use separate evidence-gated pages for hidden routes instead of guessing from a hidden title.

All 23 achievements

All 23 names come from the official Steam achievement page. Fourteen requirements are public there and nine are deliberately blank; the nine blank rows are left blank here too rather than filled in from a third-party guess. The four product unlocks are grouped on the record this site checked, so their rows name the group rather than claiming which product belongs to which name.

Requirements / limits

• Public descriptions also include GAMBLING! for all Gambling Crates, RICH! for $1,000,000,000,000, CONSUMERISM! for buying everything, and FAST! for 400 products per minute.
• Steam hides the descriptions for BAD?, UP?, INVISIBLE?, HEAVY?, OPEN?, LOOP?, SECRET?, END? and END!.
• The descriptions are hidden on Steam, not absent from the game. A full-release recording reaches the end-of-run achievement panel and reads conditions off it that the store page leaves blank.
• The conditions heard there are: put enough weight to open up; feed enough to open the gates; find and place all fuses; resolve the mining minigame; reveal the keypad; and a secret ending.
• That list is conditions only. This page does not attach them to the hidden names, because the recording does not make the pairing legible enough to publish — see the open question below.
• The list is official Steam data; it is not a promise that hidden requirements inferred by other sites are current.

Common mistakes

• Treating a third-party hidden-description list as official.
• Using achievement completion percentages as a walkthrough.
• Assuming an ending achievement condition from its name alone.

Still unverified

• What are all nine hidden requirements in the current release?Not verifiedThe official page deliberately leaves those descriptions blank; only individually corroborated routes are published elsewhere.
• Which hidden name goes with which of the six conditions heard in the end-of-run panel?Single unconfirmed reportOne recording reads name and condition close together for two of them, and appears to separate HEAVY? from OPEN? by pointing out that the weight condition and the gates condition are not the same requirement. One player's reading, machine-transcribed, is not enough to publish a name-to-condition table that readers would treat as official.
