Quick Answer

Odds bets are the ONLY bet in the casino with 0% house edge. They pay true odds: 2:1 on points 4/10, 3:2 on 5/9, and 6:5 on 6/8. A $30 odds bet on point 4 pays $60. Always take maximum odds to minimize your combined house edge.

Key Facts

  • Odds bets have 0% house edge - true odds payout
  • Point 4/10: $10 wins $20 (2:1)
  • Point 5/9: $10 wins $15 (3:2)
  • Point 6/8: $10 wins $12 (6:5)
  • With 3x odds on Pass Line: combined edge drops to 0.47%
  • With 10x odds: combined edge drops to just 0.18%
  • Lay odds (Don't Pass) pay inverse: 1:2 on 4/10, 2:3 on 5/9, 5:6 on 6/8

Understanding Odds Bets

Odds bets are unique in casino gambling - they're the only bet with zero house edge. The casino offers true odds payouts, meaning the payout exactly matches the probability. You can only make this bet after establishing a point on your Pass Line or Don't Pass bet.

Why Casinos Offer 0% Edge Bets

Casinos offer odds bets because you must first make a Pass/Don't Pass bet (with 1.4% edge). Odds bets dilute but don't eliminate the edge. They also encourage larger total wagers, which means more action and entertainment for the player while maintaining the casino's overall mathematical advantage.

Frequently Asked Questions

What are odds bets in craps?

Odds bets are additional wagers you can make behind your Pass Line or Don't Pass bet after a point is established. They pay true odds with 0% house edge - the only bet in the casino with no built-in advantage for the house. You must have a Pass/Don't Pass bet to make an odds bet.

How much can I bet on odds?

Odds limits vary by casino. Common limits are 3x-4x-5x (3x on 4/10, 4x on 5/9, 5x on 6/8), 10x, or even 100x. The more odds you can take, the lower your combined house edge. Always take maximum odds if your bankroll allows.

What does 3x-4x-5x odds mean?

3x-4x-5x means you can bet 3 times your Pass Line on points 4/10, 4 times on 5/9, and 5 times on 6/8. This system results in all wins paying exactly 6 times the Pass Line bet - $10 Pass wins $60 total with max odds on any point.

How do Lay odds work on Don't Pass?

Lay odds are the opposite of taking odds. Since you're betting the 7 will roll before the point, you risk more to win less. Point 4/10 pays 1:2 ($40 to win $20), 5/9 pays 2:3 ($30 to win $20), and 6/8 pays 5:6 ($30 to win $25).

Why take odds if expected value is still negative?

Your expected value on Pass Line remains negative regardless of odds. However, odds dilute that negative EV. With $10 Pass + $30 odds, your $0.14 expected loss is spread across $40 total bet (0.35% combined edge) instead of just $10 (1.41% edge).
