Let's look for 4 fixtures, which may not end with a draw. Rates for all three events in the match have to be over 2.00.

Check it out on the example. We pick 4 fixtures:
A Bolton - Wigan 2.50 2.55 2.80
B Mu - Arsenal 2.50 3.30 2.55
C Boca - River Plate 2.30 3.20 3.00
D Milan - Roma 2.35 3.90 2.45

Then we analyze all possibilities excluding draws.
A-1 B-1 C-1 D-1
A-2 B-1 C-1 D-1
A-2 B-2 C-1 D-1
A-2 B-2 C-2 D-1
A-2 B-2 C-2 D-2
A-1 B-2 C-2 D-2
A-1 B-1 C-2 D-2
A-1 B-1 C-1 D-2
A-1 B-2 C-1 D-2
A-2 B-1 C-2 D-1
A-2 B-1 C-2 D-2

A-2 B-1 C-1 D-2
A-1 B-2 C-2 D-1
A-1 B-2 C-1 D-1
A-1 B-1 C-2 D-1

If we bet 16 times i.e. all possibilities without draws, for 1 € for each we gain 17.80€ in the worst case and 36.50€ if we are lucky. As you can see the system can bring profits, but only if there is no draw in a single match.
