I will bet on all 10 market places and if i win any 3 of them i will be eligible for 5x profits
In accumulator betting if one of your selection is wrong then you will lose the entire bet-slip. This is why it's not easy to hit a multibet of 3 even 3+ of selections.
I see Haunebu had a post with his suggestion and I have seen the other guy offering like that but there the difference is it's not in the same match. In the same match it's actually really risky however I will never know which one will have good acceptance in the market unless I try.
So, these two I have now:
For 3 selection outcome will be 5x (you will be given max
For 5 selection outcome will be 10x (you will be given max 7 options to select 5)
For 7 selection outcome will be 20x
and
- Select 4 from 5 picks : x10
- Select 5 from 5 picks : x20
I will give try with both of these for some period of times and will see which one has good balance.
