Cases is an exclusive in-house game that repackages the popular case-opening online format into a fast-paced crypto casino game. This style of game has its roots in early 2010s video games, such as CS:GO skin trading cases and FIFA card packs. While the idea has been adapted for casinos before, MetaWin Studios has become one of the few to publish full prize tiers.
This case-opening crypto game works around a random prize reveal mechanic. Players select a case, open it, and discover what reward from the drop table they receive. Cases is a part of the MetaWin Originals selection, a series of games that lean into crypto-friendly formats. It sticks closely to the minimal UI and clean visuals of other popular Originals games.

Cases has a clean black interface that shows the game window with colored cases ready to open, with betting options sitting to the left. All gameplay features are within sight and just one click or tap away. Cases feels direct, focusing on delivering gameplay without much fuss or hidden features.
However, it is also stylish, with each round showing a visual opening animation that helps add to the anticipation. Rewards tiers are shown at the bottom of the screen, where you can see the multiplier amount and the chance of winning it. The pacing is intentionally dramatic, giving even smaller openings a sense of momentum while premium hits feel more like an event.
Low-stakes cases have modest payouts, but they can drop more often, while high-stakes cases have more volatility but bigger overall payouts. You get a real sense that there is a progression built into the game, allowing you to choose how to balance risk vs reward. Underpinning the whole game is the provably fair RNG system that ensures fair outcomes that players can verify themselves.
You find Cases in the MetaWin Originals lineup in the game lobby, which is closely linked with MetaWin Packs. Both games are reveal-driven instead of focusing on grid or slot-style mechanics.

You'll be up and running with Cases in just a few minutes once you open and fund your casino account at MetaWin. There is support for email registration, but because MetaWin is a native crypto platform, you can sign up by integrating your Web3 wallet. Join through MetaMask, Phantom, Coinbase Wallet, and 300+ others via WalletConnect to enjoy pseudonymous access.
Because deposits and withdrawals are in crypto, there is no banking friction. This allows faster near-instant transactions using BTC, ETH, and SOL, stablecoins like USDT, and also memecoins. MetaWin also supports MoonPay on-ramp payments through debit cards for non-crypto users.
After funding your MetaWin account with supported cryptocurrency, players can open the Cases lobby and browse the available selection of themed cases. Cases come in color varieties that show the volatility of the selection. Each tier has its own entry price, prize pool, and rarity structure, ranging from lower-cost options with steadier returns to premium cases built around rarer high-value drops.
Once you pick a case, use the controls on the right to select your bet size using the automatic or manual betting options. There is also a difficulty selector that allows you to choose the volatility of the game based on your risk profile. After you bet, click open to start the case reveal animation and see the random reward roll onto the screen.
Case tiers from lowest to highest are grey, light/dark blue, red, green, purple, and yellow. The simple concept behind Cases is to try to receive a reward multiplier that is higher than your bet amount. You'll have the option of opening multiple cases in a single round. This helps longer sessions feel more like continuous gameplay instead of single, standalone rounds.

One of the game's biggest transparency advantages is that the full prize ladder and rarity weighting are publicly visible before opening a case.
The basic rules are only one part of knowing how to play Cases because there are also features that enhance the overall gameplay. The standard loop of the game is straightforward and includes choosing a case, opening it, and seeing the reveal of a random reward. However, the depth comes from MetaWin Casino's structure that focuses on volatility choices.
Lower-level cases generally feature more affordable entry prices and more common outcomes, while premium cases increase volatility by concentrating more value into a smaller number of rare drops. The game is an example of casino gameplay that focuses on risk profile more than on built-in bonus features.
Every case has its own weighted RNG distribution. All possible rewards in a case have a predefined rarity weighting that decides the reward. While this is standard for all casino case opening games, Cases is backed by MetaWin Casino's ironclad provably fair system.
Each round is given a hidden server seed, client seed, and nonce. The server seed is set in-house, but nobody can tamper with it once it is set. You have the option to use an automatic client seed or set one yourself. The nonce acts as a counter for the number of rounds. This allows you to check all results using the built-in SHA-256 tool or independently to verify that outcomes are fair.
You'll find features that are designed for playing over longer sessions. Auto-open allows you to set a stake for repeated case reveals instead of manually restarting after each round. There is a history log that shows all the previous drops and outcomes. MetaWin Studios also periodically rotates limited-edition or seasonal cases tied to events, promotions, or themed collections, giving regular players new prize ladders and rarity distributions beyond the permanent catalog.
Cases RTP is towards the higher end of crypto-friendly casino games at 98%, sticking to the higher-return structure that the MetaWin Originals collection is known for. The game has a higher RTP than most slots, and higher than other Originals titles such as Bars and Plinko. This is because the volatility is built into the game for players to choose instead of being tied to bonus mechanics.
This means there is also big win potential from Cases, with a top multiplier of 10,000x and a max payout cap of $250,000. With the house edge and possibility of high-paying drops, along with options for lower volatility play, Cases works well for budget players and higher rollers.
One of the game's biggest transparency advantages is that the full prize ladder and rarity weighting are publicly visible before opening a case. Players can see the available outcomes and associated probabilities upfront, which makes the experience far more transparent than many third-party skin-trading or loot-box style platforms.
While this is a simple game, there are Cases strategies and tips you can use to get the most potential from your sessions.
Cases is not the only pick-and-reveal style game in the MetaWin Originals collection. MetaWin Packs uses similar mechanics and is also inspired by video game loot drops. Both work by opening something to receive a reward. The main difference between Cases and Packs is design, with one focusing on case and skin opening aesthetics and the other focusing on collectible card visuals.
