Your backpack is where everything you mine goes. When you break a block, the drop is added to the backpack instead of your inventory, and the backpack is emptied into money when you sell. It has no size limit on Prison, so mining never stops because it is full. Selling can be manual, on a timer, or instant, and two token upgrades make autosell faster and more profitable.
Opening it#
| Command | Aliases | What it does |
|---|---|---|
/backpack | /bp | Opens the backpack menu |
/sell | /sell all | Sells everything in your backpack now |
/autosell [state] | /as | Turns instant autosell on or off (true or false). Needs the HUNTSMAN rank or higher |
You also get a Backpack ender chest item you can right-click, and a nether star Menu item; both are hotbar items.
The backpack menu#
| Button | What it does |
|---|---|
| Sell Now (chest) | Sells the whole backpack. Boosters, mine tax and your prestige and rebirth bonuses apply, but not your autosell multiplier |
| Backpack Info (nether star) | Items held, "Maximum Capacity: Unlimited", your autosell interval and autosell multiplier |
| Item pages | Every item stack you hold, with page arrows |
| Toggle Auto Sell (emerald) | Turns timer autosell on or off |
| Upgrade Auto Sell Interval (clock) | Makes timer autosell run more often |
| Upgrade Auto Sell Multiplier (diamond) | Raises the money multiplier on autosell sales |
Selling shows "Your backpack sold for (amount)!"; with nothing to sell it says "Your backpack is empty!". If you cannot afford an upgrade: "You can't afford to upgrade your backpack!"; a successful one says "Backpack upgraded!"
Selling and what you are paid#
A sale adds up the sell price of everything in the backpack (see Mine Blocks), then applies boosters, mine tax, your prestige and rebirth bonuses and, for /sell and autosell, your autosell multiplier. The full order and a worked example are on Income Multipliers.
Timer autosell#
Toggle it in the backpack menu. While it is on, your backpack is sold automatically, and after each sale it waits for your autosell interval before the next one. You see "Your backpack sold for (amount)!" each time. The interval starts at 5 minutes and drops by 10 seconds per interval upgrade, never below 15 seconds. When it can go no lower the upgrade says "Auto sell interval cannot be higher than 15s!". It is checked every 15 seconds at most.
Instant autosell#
/autosell sells items as you mine them, roughly once per second, instead of waiting for a timer. It needs the HUNTSMAN rank or higher. Permanent Autosell, the guaranteed reward on the 7th opening of the rebirth crate you earn by rebirthing, also unlocks it permanently. See Donor Ranks. Running /autosell with no argument flips it, and /autosell true or /autosell false sets it. You see "Auto sell enabled!" or "Auto sell disabled!".
Autosell multiplier#
Autosell and /sell pay 1 plus the following:
- 1% for each Auto Sell Multiplier upgrade you bought, with no upper limit.
- 5% with the HUNTSMAN rank, 10% with SAVAGE, 15% with CAVEMAN.
Upgrades#
Both upgrades cost tokens. Neither price changes with rebirth. A rebirth does reset the upgrades along with the rest of your backpack. Each row shows the price of the level you are buying and the total spent so far.

Capacity#
There is no capacity limit, so there is nothing to upgrade and no "backpack full" interruption.
Prestige and rebirth#
- Prestige destroys everything in your backpack without paying you, and keeps your upgrades. Money left after the fee is wiped too. See Prestige.
- Rebirth empties the backpack and resets both upgrades. See Rebirth.
Mining summary#
Every 60 seconds in which you earned something, the game sends a Mining Summary to your chat with the blocks you broke and the tokens, money and beacons you earned in that minute. You can switch it off in your settings.
Tips#
- Use
/sellrather than the Sell Now button: it pays your multiplier. - Interval upgrades are cheap early and add up: the first ten levels together cost under 76 million tokens.
