What is the difference between this calculator and the Rule of 4 and 2?

The Rule of 4 and 2 assumes heads-up play, but this calculator adjusts for the actual number of players at the table. In multi-way pots, your odds are significantly higher because there are fewer unknown cards remaining.

How many outs do I have with a flush draw?

A flush draw typically has 9 outs - there are 13 cards of each suit, you have 2, and 2 more are on the board, leaving 9 cards that complete your flush.

What are pot odds in poker?

Pot odds are the ratio of the current pot size to the cost of calling a bet. Compare pot odds to your winning percentage to determine if a call is profitable.

How do I calculate poker outs for a straight draw?

An open-ended straight draw has 8 outs (4 cards on each end). A gutshot (inside straight) has 4 outs. Count carefully to avoid double-counting cards that might give opponents better hands.

Pot Odds Calculator Guide

The integrated pot odds calculator helps you determine whether calling a bet is mathematically profitable. Simply enter the current pot size and the bet you need to call. If your poker hand odds are better than the pot odds, you should call. If they're worse, you should fold.

Example:

• Pot size: $100, Bet to call: $20

• Pot odds: 6:1 (need to win 16.7% of the time)

• If your hand has 20% chance to win → CALL

• If your hand has 15% chance to win → FOLD
