The checks, one by one
| Check | Answer | The evidence |
|---|---|---|
| The cards are real | Yes | Graded Pokémon cards with an 86–95% swap-back per pack. |
| Outcomes are publicly recorded | Yes | Exact lifetime counters in Monster's own MegaETH contracts — no sampling, no windows — and 98.5% of recorded pulls verify on-chain. |
| It publishes its odds | Yes | Tier odds per pack. |
| An outsider can audit it | Yes | We read the contracts' lifetime counters directly and verify pulls as real MegaETH events. |
| Payouts work | Yes | The swap-back is exercised constantly in the feed. |
| You come out ahead | No | -4.8% realized edge, 7 days (9,178 pulls, at swap-back). |
These checks cover what's publicly measurable — settlement records, feeds, published odds, and buyback behavior. They don't verify custody, solvency, shipping, or future conduct; no outside audit can.
The one caveat
Presentation, not concealment: Monster's published tier EV is computed from prize-bucket midpoints, which overstate what typically drops — the midpoint mirage, and Monster is far from alone in it. The corrective is its own data: lifetime average card value × swap-back ÷ price, over every pull the machine has ever done, on the data page.
“Legit” and “profitable” are different questions
On average, no. Lifetime cash-out — average card value × swap-back ÷ price, over every pull a machine has ever done — is negative on every machine. That's computed from Monster's own counters, not an estimate.
The full live numbers — exact lifetime numbers per machine — are on the Monster data page, and Monster sits alongside every other site we track on the live board.

Frequently asked
Is Monster legit?
Structurally the most auditable site we track: exact lifetime counters in its own contracts, 98.5% of recorded pulls verified on-chain. Legit — and lifetime cash-out still runs below pack price on every machine.
Is Monster a scam?
No evidence of that — and Monster would be the hardest site we track to run one on. Its own contracts publish every pull and every value for each machine's entire life, and we verify those records on-chain independently. Faked numbers would contradict its own chain.
Can you make money on Monster?
On average, no — lifetime cash-out computed from Monster's own contract counters is negative on every machine. Not an estimate; its own numbers.
Is mnstr.watch part of Monster?
No — mnstr.watch is an unaffiliated analytics site about the platform (as is RipIndex). mnstr.xyz is the platform itself; this page is about that.
