Here's an idea..

Aim for 20u and then reset.

Place 1u on each number drawn and record numbers as you go. If a number hits then you remove the oldest number that you have recorded in your list and remove bet from this number. Continue until you have 20u+. If you end up with having to place chips on more than 18 numbers then reset starting with the last number drawn but this time increase the bet by 1u on each number.
Carry on until you reach 20u profit then start again with 1u on each number.

BR....not sure. Maybe play for 10% of BR so 200u play for 20. 500 play for 50?
Early signs of promise. Any thoughts welcome.
