Parlays
Off-the-board parlays are straightforward. A tie counts as a push, and reduces the parlay by one team, so a 5-teamer pays as a 4-teamer.
Parlay cards can be ties win, reduce (tie), or lose. Read the fine print and be careful! At one offshore book the rules say "Player must win all games to win." That's the same as being a ties-lose card.
Teasers -- Off the Board
Off-the-board teasers (teasers constructed from the live line on the betting board) of more than two teams almost always result in a reduction, so go 2-0-1 and you get paid like it was a 2-teamer.
Off-the -board 2-team teasers get complicated based on house rules. At most books, if one of your teams ties the rule is the teaser is a push, regardless of whether the other game wins or loses, as there's no such thing as a one-game teaser. However, some books grade 1-0-1 teasers as a push and 0-1-1 teasers as a loss. Read all the rules.
Teaser Cards
Some books are ties win, some ties lose, and some ties reduce. Again, read the fine print.
Advantage Teaser Play
Some offshore books allow you to play a 2-team teaser with an "open spot." Millenium used to be one of them. If the first game lost, it would grade the teaser as a loser. But if you could tie it to a second game that pushed, you could resurrect your money. It led to funny situations where sharps would frantically try to pick second legs of teasers that would save their wager, usually teasing a -3 team to +3 trying for the optimal chance to push.
