The rules are the same as with normal roulette.

I think it's on every casino with Playtech platform and Bet Voyager too.

Personally I've tried it from Paddypower casino (only on downloadable version)

If you bet 1 $ on 1 wheel you could win up to 35 $ net , if you decide (optional) to have the same bet on 2,3,4,5 or 6 wheels simultaneously it would cost 2fold,3fold,4fold,5fold up to 6fold and also in case of win the gain would be multifold.

The same could be applied at B&M casinos by betting multiple tables on the same time.

The big question remains, does this way makes difference in our bottom line?

Is it better than risking the same 36 units in one number at one table?

We could bet a number on 6 different wheels/tables for 6 consecutive spins or 1 number on the same wheel/table for 36 spins.

In all cases the risk is 36 units, but the possible profit varies.
