# Parlays

> Multi-leg accumulator predictions on ezpz.fi.

## What is a parlay?

A **parlay** combines two or more legs into a single prediction. **All legs must win** for you to receive a payout. If any leg loses, the entire parlay loses.

Odds multiply across legs:

```
Combined odds = (leg1 × leg2 × ... × legN) / 100^(N-1)
Max payout = net_stake × combined_odds / 100
```

A 2% parlay fee applies to the stake.

## Current scope

<Note>
  M1 parlays are **soccer-only**. You cannot mix sports legs with crypto or pump.fun markets in a single parlay yet.
</Note>

Build a parlay at `/parlay` or by adding legs from sports market cards.

## Anti-correlation rule

You cannot include two legs from the **same match** in one parlay. The platform enforces this on-chain to prevent correlated predictions that would not be true independent outcomes.

## The parlay pool

Parlays are backed by a separate **LP pool**, not individual market vaults:

| Actor       | Role                                                           |
| ----------- | -------------------------------------------------------------- |
| **LPs**     | Deposit USDC into the parlay pool; earn from losing parlays    |
| **Players** | Stake against the pool; win multiplied payouts if all legs hit |

Single-market predictions and parlay predictions use different funding sources. See [Outcome tokens](/concepts/outcome-tokens) for how single predictions settle.

## Settlement cases

| Case               | Result                              |
| ------------------ | ----------------------------------- |
| All legs win       | Full max payout                     |
| Any leg loses      | \$0                                 |
| Some legs voided   | Odds recalculated on remaining legs |
| All legs voided    | Full stake refunded                 |
| Below minimum legs | Full stake refunded                 |

## Leg resolution

Each leg resolves independently when its underlying market resolves. A permissionless `resolve_leg` instruction reads the market outcome and marks the parlay leg won, lost, or voided. Settlement runs once all legs have a final state.
