# Parlay Multipliers

A parlay is a type of bet that will be available to all users in Rollbit's upcoming Sportsbook.

A parlay allows sports bettors to include multiple wagers into a single bet. If all bets come in, the win will be much greater than if the bets were placed individually!

{% hint style="info" %}
A parlay is also known as a Accumulator ("acca"), Multi and Combo Bet 💡
{% endhint %}

We're excited to announce that Sports Rollbots holders will get exclusive multipliers applied to their parlay winnings. These multipliers will be known as ***Combo Boosts***. Sports Rollbots holders will enjoy over 100% Combo Boosts! :rocket:

The teeth trait determines the parlay multiplier/combo boost value for each Sports Rollbot. Check out the values for each teeth trait [here](/rollbot/sports-rollbots/trait-rarity-breakdown.md).
