anyone played like this before?

[7]

Building chips progressively around a couple of numbers. With 4 splits on each number as hedge bets, adding a chip on each split every 7 spins until one of those 2 main numbers pops. Or just adding chips to the splits that hits for the repeats on theses little chip islands. Working well for now, though I stop adding chips at ÂÃ,£25 max.
