System 4/12 Bet Calculator

What is a System 4/12 Bet?

A System 4/12 Bet is a type of combination bet where you select 12 different selections, and all possible 4-pick combinations from those selections are formed into separate bets.

How Does a System 4/12 Bet Work?

• You are placing 495 separate 4-fold accumulator bets (since there are 495 ways to combine 4 selections out of 12).
• You need at least 4 correct picks for some of your accumulators to win.
• If more selections win, the number of winning accumulators increases, leading to a higher payout.

Example of a System 4/12 Bet

Let’s say you place a $1 bet per combination on a System 4/12 Bet, making your total stake $495. Each event has odds of 2.00.

Possible Outcomes:

• If 4 selections win: Only 1 accumulator wins. Payout = $1 × 2.00 × 2.00 × 2.00 × 2.00 = $16.
• If 5 selections win: 5 accumulators win. Payout = 5 × $16 = $80.
• If 6 selections win: 15 accumulators win. Payout = 15 × $16 = $240.
• If 7 selections win: 35 accumulators win. Payout = 35 × $16 = $560.
• If 8 selections win: 70 accumulators win. Payout = 70 × $16 = $1,120.
• If 9 selections win: 126 accumulators win. Payout = 126 × $16 = $2,016.
• If 10 selections win: 210 accumulators win. Payout = 210 × $16 = $3,360.
• If 11 selections win: 330 accumulators win. Payout = 330 × $16 = $5,280.
• If all 12 selections win: 495 accumulators win. Payout = 495 × $16 = $7,920.
