# Gachas

Every pack and machine with its expected value, odds and chase cards.

The **Gachas** page at [/g](https://vollector.id/g) is a live catalog of mystery packs and gacha machines from the platforms we support, with all the math done for you. Instead of guessing whether a pack is worth opening, you get the numbers up front and can compare every pack side by side.

Each pack shows its pull price next to a full set of metrics: **Expected Value** (the average worth of a single pull) and EV Yield, **Gross EV** after the platform's instant buyback rate, a **Volatility** rating, **Risk-Adjusted EV**, and a **Win Rate** read straight from the published odds. The data is live and refreshes about once a minute, so the values track the real market.

Open any pack for the full breakdown: a rarity and odds table with the value bracket of each tier, and the **chase cards** still sitting in the machine's inventory pool. When you are ready, hit Open on the issuer to pull directly on their platform.

Prefer to hunt a specific item instead of a whole pack? Switch to the [Collectibles](https://vollector.id/g/collectibles) tab. It flips the catalog around and lists every individual item still sitting unpulled across the machines, graded cards, watches, sneakers and more, so you can search straight for the chase you want. We only list an item when its odds are knowable from the provider's own published data, so you never see a guessed number.

For each item you get the exact **Hit Odds** on a single pull (as a percentage and as "1 in N"), which pack it lives in, its market price, the **Expected Cost to Hit** (the average spend to land it, pack price ÷ odds), and a **Best Value** read of what you get back per dollar chased. Sort by any of these or filter by price, odds, expected cost, availability, platform and category, then hit Open to pull that item's pack on the issuer.
