System Bet (Combination Tickets)

System bets split your selections into multiple combos (doubles, trebles, etc.), allowing **partial returns** when one leg fails. Learn unit cost, payout logic, EV math, and when to use them responsibly.

System Basics

A system bet places multiple permutations across your selections (e.g., all doubles and trebles from four picks). You pay for each combo as a separate unit. The trade-off is **higher total stake** for **reduced all-or-nothing risk** versus a single accumulator.

Cost & Payout Math

Total unit cost equals the number of combos. For n selections and k-folds:

Units = Σ C(n, k) for each included k (e.g., doubles k=2, trebles k=3, etc.).

Payout sums returns from each winning combo. A single loser may still pay if other legs form winning doubles/trebles.

Example — Yankee (4 selections, 11 bets)

  • 6 doubles, 4 trebles, 1 fourfold. Stake per bet = 1 unit → Total stake = 11 units.
  • If one leg loses, surviving doubles/trebles can still pay; fourfold is dead.

EV & Correlation

  • All legs must be +EV: System bets multiply the bookmaker’s margin if legs are neutral/negative EV.
  • Correlation drag: Legs from similar markets/teams/leagues increase joint failure risk. Keep systems diversified.
  • Edge dilution: Extra unit cost means you need robust edges or higher odds to justify the system.

When to Use System Bets

  • You have several small edges (e.g., 3–5%) and want protection if one leg fails.
  • Liquidity is good; prices won’t collapse before you place all legs.
  • You’re tracking performance by system type and controlling correlation.
Responsible Play: System tickets reduce “all-or-nothing” variance, not risk. Keep total unit outlay sensible and comply with local regulations and operator terms.
