MNSTR pack simulator
Open simulated MNSTR packs using the odds it publishes for its Pokémon and One Piece packs, and see the RTP (return to player: what comes back for every dollar in) before and after a session. Values are MNSTR's own; nothing here is a real pull.

Expected RTP
Enter a pack price to see the expected RTP.
On some packs the published odds imply an RTP at or above 100%. That is a statement about MNSTR's own valuations, not market prices, and not an edge: the listing records what users report about its displayed values, and sell-backs take a haircut.

The odds behind this
Transcribed from Starter (Pokémon)'s page on Oct 8, 2026. Bands are ranges of MNSTR's own fair market value (FMV) per card, the same figure its 'up to 95% FMV' buyback is quoted against; the homepage FAQ says odds use inverse value weighting (a $100 card is 10x more likely than a $1,000 card) and the pages do not say which comps feed the FMV.
| Band | Value | Chance | Average value | Share of EV |
|---|---|---|---|---|
| Common | $30 to $50 | 73.07% | $36 | 48% |
| Uncommon | $50 to $100 | 17.66% | $65 | 21% |
| Rare | $100 to $200 | 7.22% | $130 | 17% |
| Epic | $200 to $500 | 1.86% | $286 | 10% |
| Legendary | $500 to $3,166 | 0.19% | $1,115 | 4% |
Source: Starter (Pokémon) on MNSTR. Each pack page has a 'Pack Odds' list of five tiers (COMMON, UNCOMMON, RARE, EPIC, LEGENDARY) with a dollar band and a percentage to two decimals, plus 'Average pull value' with the percentage above price and the pack's buyback rate. The API carries the same figures unrounded (minFmv, maxFmv, probability, currentEV); this file records them rounded to two decimals, which is what the page prints. Prices are USD (priceUsd); the on-chain price field is an 18-decimal token amount and payment is in USDm or by card. All 6 gacha packs the storefront listed on 2026-10-08 are included (Pokémon Starter $50, Great $100, Monster $250, Ultra $1,250; One Piece Adventure $150, Outlaw $500); the homepage says sports packs are 'Coming Soon'. Buyback rates differ by pack (86% Starter up to 95% Ultra), so 'up to 95%' applies only to the top tier. The storefront also lists a Dutch-auction sealed product (Ascended Heroes, seed $23, reserve $13) and a closed blind drop, neither with odds tables. Promos in the storefront (a 'Lucky Boost' on Adventure, 'Dupe Shield' on Great) may change effective odds for signed-in users; we could not observe that. The earlier research note of Starter at 72.23/18.55/7.48/1.59/0.15% (2026-09-29) differs from today's 73.07/17.66/7.22/1.86/0.19%, consistent with the page's claim that odds move with the pool. Pack prices are in USD; payment is in USDm or by card. The stated average is the 'Average pull value' printed on each pack page. Buyback differs per pack (86% to 95%).
How the simulation works
RTP is return to player: value pulled divided by money spent. Each simulated pack draws one value band using the probabilities MNSTR publishes, then a value inside that band. Platforms publish the bands but not where values fall inside them, and that gap matters: a $25 to $200 band averages $70 if values spread log-evenly, $112 if evenly, and less if most cards sit near $25. So the expected RTP is shown as a range from bottom-heavy to evenly spread, and the simulation draws log-evenly in between. MNSTR prints its own average value per pack, so the draws are calibrated until the model's average matches that figure. Real pulls come from a finite card pool and the platform's pricing can move, so treat every number as an estimate at MNSTR's own valuations, which may differ from what the same card sells for elsewhere.
MNSTR pays 95% crypto buyback, so cash after selling back is lower than the value pulled. Shipping fees and taxes aren't modelled.
18+. Pack opening is chance-based spending with real money. Whatever the odds imply at the platform's own values, cash in hand is lower after the buyback haircut, fees and the gap to market prices. Only spend what you can afford to lose. See the MNSTR listing, other simulators, our guides on EV and buyback and the methodology.
