What is a System 3/7 Bet?

A System 3/7 Bet is a type of combination bet where you select seven different selections, and all possible 3-pick combinations from those seven selections are formed into separate bets.

How Does a System Bet 3/7 Work?

• You are placing 35 separate 3-fold accumulator bets (since there are 35 ways to combine 3 selections out of 7).
• You need at least 3 correct picks for some of your accumulators to win.

Example of a System 3/7 Bet

Let’s say you place a $1 bet per combination on a System 3/7 Bet, making your total stake $35. Each event has odds of 2.00.

Possible Outcomes:

• If 3 selections win: Only 1 accumulator wins. Payout = $1 × 2.00 × 2.00 × 2.00 = $8.
• If 4 selections win: 4 accumulators win. Payout = 4 × $8 = $32.
• If 5 selections win: 10 accumulators win. Payout = 10 × $8 = $80.
• If 6 selections win: 20 accumulators win. Payout = 20 × $8 = $160.
• If all 7 selections win: All 35 accumulators win. Payout = 35 × $8 = $280.
