Monster (MNSTR): exact lifetime numbers, no sampling

MegaETH · graded Pokémon packs · exact lifetime counters (we verify on-chain) · data refreshed 2026-07-10 08:37 UTC · by RipIndex, independent — methodology

Monster (mnstr.xyz, ticker MNSTR) rips graded Pokémon cards on MegaETH — and it's the rare site whose contracts expose exact lifetime counters per pack: every pull ever, every card value, straight from the machine itself. No sampling, no windows. RipIndex reads those counters, banks the live feed, and independently confirms recorded pulls as real on-chain events (98.7% verify).

Lifetime, from Monster's own counters

Pack	Price	Lifetime pulls	Avg card value	Cash-out edge (lifetime)
Starter	$50	90,648	$55.73	-4.1%
Great	$100	18,723	$106	-5.5%
Adventure	$150	4,667	$156	-3.0%
Monster	$250	26,259	$293	+7.7%
Outlaw	$500	7,070	$514	-3.5%
Ultra	$1,250	2,812	$1,284	-2.5%

The last column is the whole story: average card value × Monster's buyback ÷ pack price, over the machine's entire life. Published tier EV reads higher — it's computed from bucket midpoints, which overstate what typically drops (the midpoint mirage, and Monster is far from alone in it). The lifetime number is the one your wallet meets.

Frequently asked

Is Monster (MNSTR) legit?

Structurally, it's the most auditable site we track: its contracts publish exact lifetime counters, and 98.7% of recorded pulls verify as real on-chain events. Legit — and still −EV: lifetime cash-out runs below pack price on every machine.

Why does Monster's published EV look better than RipIndex's number?

Published tier EV is computed from prize-bucket midpoints, which overstate typical drops. Our headline is lifetime average card value × buyback ÷ price — from the site's own exact counters. That number is lower, and it's the real one.

Is mnstr.watch the same thing?

No — mnstr.watch is an unaffiliated analytics site about the platform. This page covers mnstr.xyz itself, with our own on-chain verification on top.
