How the Buy the 4 and 10 works

Instead of placing the 4 and 10 (9:5 payout, 6.67% edge), you can buy them: they pay true odds (2:1) minus a 5% commission. At most casinos the vig is $1 per $20, rounded down, so a $25 buy costs just $1 in vig and pays $49 instead of $45 placed.

Bets: $25 buy on 4 and 10 (vig on win).

How we tested it

Each session is 100 rolls (about an hour at a busy table) starting on a new shooter, using standard Vegas rules: 3-4-5x odds, casino payouts rounded down, place bets off on the come-out, and a $5,000 table max. At the end of the hour we stop betting, take down removable bets and let contract bets finish. "Down $500" counts any point in the hour where the session was $500 behind. Dice come from a cryptographic random generator. Results are practice estimates, not predictions.

Common questions

What's the vig on a buy bet?

Usually 5% of the bet, often rounded down to $1 per $20 (so $1 on $25 to $39). Some casinos charge it only when you win, which is best for you.

Should I buy the 6 and 8?

No. Placing the 6 and 8 at 7:6 (1.52%) is cheaper than buying them.

What about the 5 and 9?

Buying 5/9 at $40+ with vig on win drops the edge to 2%, better than 4% placed.
