Juice - interest charged to bet; example: 10% juice to bet the OVER means you bet $110 to win $100 OR bet $100 to win $90. You only pay juice when you lose
Liveline - betting during the game; spread, over/under adjusts during the game
Moneyline - pick whichever team wins, with no point spread. Moneyline odds change based on how strong one team is versus another
Nick line, Nickel line - line/account that charges 5% juice instead of the standard 10%
Parlay - combine 2 or more single bets to increase payout; push reduces/removes it from counting (example: 2 team parlay turns into straight bet). All bets in parlay have to hit for parlay to survive; if any bet in a parlay fails, parlay is dead. No juice is charged for parlays
Push - tie, no winner
Spread - how much one team is favored over another, or how many points one team is getting from the favorite (usually before quarter, game, half starts)
General parlay payout guide (depends on juice):
Bet $100, win:
2 team: $260
3 team: $600
4 team: $1000
