Begin a session during a croupier switch.
Remember to select a new game when a croupier comes to the table, dont try to save a game from an earlier session with a croupier, since I have noticed that the croupiers have different behaviours between the sessions, sometimes they are predictable and sometimes they aren't.

Start by selecting wich number the ball starts from.
When the dealer make the first spin, select the speed of the wheel (slow medium or fast). Some dealers makes faster spins than other. I usually select Medium, if its not super slow or super fast to start with. Same with the strength of the spin. If its not super hard och super weak I select 3 (medium). In time after you have seen many spins, you're getting better on deciding the strenght of the spins. Not by only seeing the spin, but by listening on the spin and speed of the ball.
Press next.
Since no data is collected, it will say
"No statistics found yet".
Keep filling the app with data until you have enough information to decide if its worth playing or not.

Some spins are hard to decide if its worth betting. This picture is an example. It shows that most of the spins have gotten all around, and not on a specific area. BUT, the two latest spins with this strength and wheelspeed had identical behaviour, and if the current spin would have the same behaviour as the two latest spins it would have a big chance to drop near 28 or 7. I would only bet on this if it's going well and if my currency is above what I've started with.
Other spins are easier to decide if you should bet or not. This is a screenshot from one of my clips on Youtube.

Since I bet on 4 neighbours on both directions i choose 21 to cover up the whole red marked area.

Once again, since I bet on 4 neighbours on both directions i choose 18 to cover up the whole red marked area.

The wheel was spinning fast so it's the purple lines I'm looking at.
My tactics for the moment is to add 600 chips to the account. I aim for around 1600 chips. Since one bet is 75 chips I am forced to only bet on spins like in the previous 2 pictures, and I'm forced to be more careful. If everything goes well and I reach my limit, I withdraw everything, leaving 600 units for the next day. It takes time and patience to find a dealer that is worth playing on, but its worth it in the long run. Some days I could sit for hours just to wait for a good dealer to bet on.

At the beginning I created this application for personal use, but after a good feedback and many requests via Youtube I made it public, so this is still an ongoing learning proccess for me too.

We learn new things everyday, please take your time and post your hints and tips to share with everyone including me.

And it would be awesome if you could record and share your sessions/experiences on Youtube by posting a link in the comment field.

Know when to stop! Set a limit for the day, and when you reach your limit, quit playing. If you double your money you should be satisfied and come back the next day. And don't get greedy, be tactical. The more you play, the higher is the chance that you get greedy and bet on spins like this one too often. And in the end you might loose.
