Rare Mystery Box cat

Maxwell in Gamble With Your Friends

Maxwell is one of the two rarest Mystery Box drops in Gamble With Your Friends. This page answers the questions players actually ask: what he does, how rare he is, how to trigger the “Oi” prompt, and whether he still breaks the elevator.

What does Maxwell do?

Maxwell is a very rare Mystery Box cat. The current game data describes him as an “adorable, chunky cat” and does not show a verified money, quota, payout, or upgrade effect. His confirmed role is a rare novelty / cosmetic drop.

“Rare” is not the same as “strong”. Nothing in the fixed game data ties Maxwell to your run’s economy.

A zero internal price is a data value, not a free shop listing. The verified acquisition route is the Mystery Box loot pool.

How do you get Maxwell?

The only verified acquisition route is the Mystery Box loot pool.

  1. 1Buy a Mystery Box
  2. 2Open it during the run
  3. 3The game runs one weighted loot roll
  4. 4Maxwell carries a weight of 0.2
  5. 5≈0.7874% chance per box

Maxwell and Ratto are the two lightest entries in the verified loot table, so they are the two rarest drops.

Can you buy Maxwell directly?

No verified direct purchase. Every floor lists an internal price of 0 Tickets, but that asset value should not be read as a normal free shop listing.

Maxwell drop chance calculator

Estimate the chance of at least one Maxwell after opening a number of Mystery Boxes.

Chance of at least one Maxwell
17.93%

P(at least one) = 1 − (1 − p)^N, with p = 0.0078740157

Every box is an independent roll. More boxes raise the chance, but they never guarantee the drop.

1 in 127 does not mean Maxwell is guaranteed within 127 boxes. It is the average number of boxes per drop across many independent opens.

How do you make Maxwell “Oi”?

Partially verified

Maxwell shows an “Oi” interaction prompt in the live game, and players are actively asking which input triggers it. The current production database does not yet contain the binding needed to publish a verified key.

DeviceCurrent verified input
KeyboardNot closed yet
ControllerNot closed yet
Steam DeckNot closed yet

Check your current Input Mapping screen first, because v1.0.30 added configurable input mappings.

A prompt that will not respond can be an input-mapping problem rather than a Maxwell problem.

Does Maxwell affect luck, money or quota?

No verified effect in the current production data.

Does Maxwell increase luck?

No verified effect. The fixed item data has no luck field.

Does Maxwell improve gambling odds?

No verified casino modifier.

Does Maxwell help with quota?

No verified quota effect.

A cat this rare makes players suspect a hidden buff. The data checked here only proves spawn, description, price and Mystery Box weight.

Is Maxwell rarer than Ratto?

They are tied.

ItemWeightChance per boxEconomic effect
Maxwell0.2≈0.7874%None verified
Ratto0.2≈0.7874%None verified

Both entries carry the same verified weight and therefore the same drop chance. Neither has a verified economic effect.

Maxwell is tied with Ratto among the rarest verified Mystery Box drops — not the single rarest item.

Does Maxwell still break the elevator?

No. The original elevator bug was fixed in v1.0.7 on May 4, 2026.

At launch, pulling Maxwell (or Ratto) from a Mystery Box could jam the elevator doors on the way back. The official v1.0.7 patch notes state that Ratto and Maxwell no longer break the elevator.

Outdated advice

“Never pick Maxwell because he always breaks the elevator.”

Current status

Fixed since v1.0.7. Launch-week warnings no longer match current versions.
