2/3 system

A 2/3 system bet is a way to place a wager on 3 events in 3 different combinations (doubles) and win money if 2 or more pairs are correct (depending on the odds).

Remember: The 1st number (2) tells you how many events are in each combo, and the 2nd number (3) tells you how many events you have to choose from.

Steps to Place a System Bet:

  1. Pick your bets: Choose 3 events from any sport or market you like.
  2. Select 2/3 System Bet: Your bet slip will automatically create 3 doubles from your 3 selections.
  3. Place your bet: Enter your stake on your bet slip and make your wager.
  4. Collect your payout: Get paid based on the odds and the number of winning doubles.
  5. Lose your stake: Lose your bet if only one event wins.

2/3 System Bet Examples

Example 1: Jackpot 

In this example, you hit all 3 picks and win all 3 doubles. The 3 football teams you chose are: Chelsea, Real Madrid, and Bayern Munich. Here’s how it goes:

DoubleOddsResult
Chelsea and Real Madrid1.5 x 2.0 = 3Won
Chelsea and Bayern Munich1.5 x 1.8 = 2.7Won
Real Madrid and Bayern Munich2.0 x 1.8 = 3.6Won

If you bet $30 on the system, each double gets $10 of your stake ($30/3=$10). So, using this calculation, you get $93 as a return:

Return = ($10 x 3.0) + ($10 x 2.7) + (10 x 3.6) = $93.

This means you get a profit of $63 ($93 – $30). 

Example 2: Narrow Escape 

What if things didn’t go as planned, and you missed one pick (Real Madrid)? 

DoubleOddsResult
Chelsea and Real Madrid1.5 x 2.0 = 3Lost
Chelsea and Bayern Munich1.5 x 1.8 = 2.7Won
Real Madrid and Bayern Munich2.0 x 1.8 = 3.6Lost

Using the same logic as before, you get:

Return = ($10 x 2.7) = $27. 

This means that in this case you get a loss of $3 ($30 – $27). 

But don’t worry, you don’t have to do the math yourself. You can use System Calculator to find out how much you can win with any stake and any odds. 

Pros and Cons of a 2/3 System Bet

ProsCons
Backup plan: Win or break even if 1 pick fails, unlike a parlay.Smaller reward: Get less money than a 3-fold parlay if all picks win.
Lower risk: You only lose 1/3 of your stake per double.Trickier calculation: Deal with 3 different doubles instead of one simple parlay.
More freedom to choose: Pick any sport or market for your selections.Fewer options to find: Find fewer bookies that offer 2/3 system bets than a parlay.
