Live Betting is offered on straight bets and parlays.
With parlays, you can combine multiple Live selections together, and combine Live with pre-game selections.
It is not possible to add Live Bets into teasers.
Please keep in mind that with all Live Betting, limits, in general, are lower than pre-game.
When making parlays, even a single Live Betting selection will affect the max wager allowed. For example, in a 4-team parlay, with 3 pre-game bets and only 1 Live Bet, the amount you can bet will be based on Live Bet limits.
