Got myself a new pc so had less time to spend, but I did get to 900 spins (real spins) and never lost a full sequence - twice the same pattern on each game, in a row.
I've played by sets of 100 spins, 3 bet mini games
I've had however, as expected, matches between the pattern layed by the rng and the real spins, but I've noticed it was nearly always when rng gives a pattern that has a double, like 113, 221 etc ..
I've always recouped with a few spins, or just two, because I've sometimes increased the bets to recoup faster.
This is the weakness of this play: After the first loss, if another match happens while I'm recouping it, it's game over. Because I recoup with 5 or 10 units bets; playing 1 4 13 makes a loss of around 40£ , a progression lost at say 10 30 90 would be very bad. And I'm sure it can/will happen.
So I'm hitting a wall here, having both games matching at the right time is still quite rare, but the recoup part is to risky. Always works, but too risky.
I've got an idea for a tweak and will test further, any suggestion is welcome
