Auto-buy rules buy showcase safes for you — at night, at work, any time. A safe appears about 13.3 times a day and most of them are taken by rules, so a good rule is the main tool of an active player.
Three rule types
Auction
the moment it appears, first
At the start price
right after the auction
On a price drop
when the price reaches the target
| Rule | When it fires | Price | Weight |
|---|---|---|---|
| Auction | The moment the safe appears, before everyone | Start + steps, up to the limit | Maximum |
| At the start price | The moment it appears, if no auction won | 510 AMA2 | Maximum, 1 AM = 14.57 |
| On a price drop | When the price reaches X% of the start | X% of 510 | Lower, 1 AM dearer |
The "price drop" rule
You set a percentage X of the start price. The rule fires when the safe price falls to it:
t = T × (P0 − X·P0) / (P0 − P1)
The price never falls below 17% of the start (87 AMA2). A rule with a lower X buys in the last minute at the minimum price.
| Target X | Safe price | Weight | 1 AM |
|---|---|---|---|
| 90% | 459 | 31.3 | 14.68 |
| 70% | 357 | 23.8 | 15.02 |
| 50% | 255 | 16.3 | 15.65 |
| 30% | 153 | 8.8 | 17.37 |
| ≤ 17% | 87 | 4.0 | 21.86 |
Auction
You set a step (%), the number of steps and a limit (% above the start price). Bids grow with compound interest:
bidk = P0 × (1 + step)k ≤ P0 × (1 + limit)
The highest maximum bid wins; the winner pays their first bid above the nearest rival's maximum (second price)
Example: step 5%, 4 steps, limit 20% → bids 536, 562, 590, 620 AMA2. If the rival's maximum is 536, you pay 562, not your maximum.
Queue and priority
- At an equal price or moment the player with the higher account level goes first, equal levels — at random.
- If the balance lacks AMA2 for the price or BNB for gas, the rule is skipped and the safe goes to the next one.
- Rules: 2 at the start and +1 for every 2 account levels. A rule can be paused and resumed.
