Reduced Juice

Reduced juice (sometimes called “low vig” or “tight pricing”) refers to betting markets offered with lower-than-standard vig. The most common example is -105/-105 pricing on spreads or totals, instead of the standard -110/-110.

How It Works

The standard pricing structure on most US spreads and totals is:

  • Side A: -110 (risk $110 to win $100)
  • Side B: -110 (risk $110 to win $100)
  • Combined implied probability: ~104.8%
  • Vig: ~4.5%

A reduced-juice market would offer:

  • Side A: -105 (risk $105 to win $100)
  • Side B: -105 (risk $105 to win $100)
  • Combined implied probability: ~102.4%
  • Vig: ~2.4%

Same bet, much lower margin for the bettor to overcome.

Why It Matters

Reduced juice is mathematically meaningful:

Lower break-even threshold. At -110, you need to win 52.4% of bets to break even. At -105, you need only 51.2%. That 1.2 percentage-point difference is substantial — over hundreds of bets, it’s the difference between losing money and breaking even, or between breaking even and being meaningfully profitable.

Reduced compounding effect. When parlaying multi-leg bets, lower per-leg vig dramatically reduces the total parlay vig. A 4-leg parlay at -105 each has a much lower effective hold than the same parlay at -110 each.

Better arbitrage opportunities. Reduced-juice books on one side of a market often combine with retail books on the other to produce arbitrage edges. The lower the vig on either leg, the more frequently arbs appear.

Where to Find Reduced Juice

Sharp books offer it as a default. Pinnacle’s standard vig on major markets is around 2-3%, effectively reduced juice on every market.

Some US sharp-leaning books specialize in it. Bookmaker.eu has historically offered reduced-juice pricing across various markets. A few smaller sharp-leaning books (5Dimes prior to its closure, others) made reduced juice their primary product.

Mainstream books offer occasional promotions. Major US retail books occasionally run “Reduced Juice Tuesday” promotions or similar — temporarily offering -105/-105 instead of -110/-110 on selected markets. These promotions are -EV friction for the book but acquire customers.

Some books offer it on niche markets. A few books offer reduced juice consistently on specific markets (game lines but not props, or specific sports) as a competitive differentiator.

Practical Implications

For a regular bettor:

A book offering reduced juice is mathematically better than one offering standard juice on the same bet. All else equal, prefer reduced-juice options when available.

Don’t overweight reduced-juice promotions. A book running a promotional reduced-juice day may have other factors (worse customer service, higher restrictions) that offset the pricing advantage. Evaluate the whole package.

Combine reduced juice with line shopping. The biggest value comes from combining good prices with low vig. A reduced-juice book offering an off-market line is the best of both worlds.
