A boost is a timer. A Lucky Block is a one-shot crate. They are often granted together and they do different jobs.
Boosts
| Boost | What it changes | Durations on record |
|---|---|---|
| 2x Cash | Doubles cash from selling loot | 15 minutes, 30 minutes, and a Super 2x Cash variant at 30 minutes |
| 2x Bite | Chomps in the window count twice toward a stronger jaw | 15 minutes and 30 minutes |
The countdown starts when you redeem the code, whether or not you are selling or chewing. Start 2x Bite when you are already training. Loot first, then start 2x Cash, then sell before the timer hits zero. One player watched "1 minute and 24 seconds left" and timed the walk back so the sale landed inside the window. A doubled payout at the seller is the other confirmation.
If you see no countdown and sales look normal, do not plan a big sell around the boost.
Stacking is not documented. The exact stat behind 2x Bite, wall damage versus training gain, is not specified beyond the "stronger jaw" description. No in-game cash purchase for these boosts is described. They rotate with codes. The strings that used to grant them are expired. See Codes.
A cold storm in one session gave about 10 minutes of double wall damage, with money also looking doubled. No trigger or schedule is known.
Lucky Blocks
| Variant | How it has been obtained | What opened |
|---|---|---|
| Secret | Older codes, and one in-game purchase under 40,000 cash | Sellable loot. One purchased block produced an item narrated at 175 million. No fixed pool |
| Ethereal | Codes that paired 1 block with 2x Bite for 30 minutes | Contents never documented |
| Divine | RELEASE, and a September rotation that also gave 2 Secret blocks and 2x Bite for 15 minutes | Earth, a Divine item. About $40 billion on the ground, $80 billion after a rebirth sale. Those grant codes are expired |
Open a block when you can use the item. For a huge Divine-style pull, the September route was: rebirth while the item is still in the bag, then sell so the multiplier applies. Whether Earth is still inside a Divine block in the World 6 build is unknown, because no current-build opening has been recorded. Earth still exists as world loot in the divine zone, which is a different route.
Mythic chests and fortune boxes heard in videos were not confirmed as Lucky Block variants.
Admin Hat Charm is a code item, not a block drop. It is the documented reward for ADMINABUSE, which is still printed in the official description.
