jj i will give you a gift here that works at casinos
likely readers are going to forget this or brush it off
which is fine by me.. but I feel generous today. ok.
don't martingale black/red. or even/odd, etc.
Step 1: Choose if you want to sit at the back end of the table or the side.
Step 2: If on side, you play the 3 columns. If on end, you play the 3 rows.
Step 3: Wait for a spin. No play. You can also scope the table and wait for a double occurance
of a particular row or column, or even wait for a 0/00, if wicked serious.
Step 4: Place your chips on the opposite two rows or two columns from the last spin.
This bet pays 2/1 which is 1/1 even after the automatic sacrifice of 1 row/column.
Step 5: Keep playing those spots until they hit, martingaling.
Step 6: After it hits, switch off to the opposite two.
Step 7: Repeat this process until you feel you've earned enough then move to another table.
I also have a private system for blackjack that is a martingale variant like this.
It actually infuriates other players at the table, though.
