Waka through di system
Win dey move one step forward. Loss, or di fourth win, dey go back to di start.
Stakes and results dey in units of di base bet.
Di Plan
Bet 1 unitmoniUnitDi base stake wey system or player dey work with. Dem dey describe progressions in units so dat dem go fit work for any table.Read di whole tin →. If you win, bet 3 (di 2 wey dey di table now plus 1 more from our own). If you win again, bet 2 and keep di rest. For di third win, bet 6. Di fourth win go complete di sequence for +12 units; any loss go take you back to 1. Dem arrange di sequence so dat if you lose for step two, e go cost 2 units net; for step three e still leave us +2 (we don dey +4 afta step two and we risk 2); and for step four e leave us level (we dey +6 and we risk 6). Wetin dey attract pipo na sey losses for step three and four no dey cost plenty of our own moni.
Spins 1–30
Eighteen attempts. Ten lose for step one (−$10 each), five for step two (−$20 each), two for step three (+$20 each), and one complete for spins 27–30 (R R R R, +$120). Net −$40 afta 30 spins, and e don reach −$160 for spin 26. Di sequence wey complete be like sey di system dey work; na di 5.6% wey come as e suppose come.
Spins 31–60
Fifteen attempts: one complete for spins 44–47 for +$120, two reach step four and lose dia (each one na $0 net: +$60 wey we win, then $60 wey we stake and lose). Net −$10 for dis part; di final na −$50; di highest na +$80 for spin 47. Two completions for 33 attempts, when di expected na 1.8: na fair sample.

- p25 −$520

Di Accounts
Di total wey we bet na about $1,200, compared to $600 for flat betting. Expected lossmathsExpected lossExpected value times di total moni wey you bet; di average amount wey you go lose for one session or one period.Read di whole tin → na $32; wetin happen na −$50, inside one standard deviationmathsStandard deviationSquare root of variance; di normal distance between one result and di expected value.Read di whole tin →. Di way dem design di sequence mean sey most of di moni wey dey di table for one long attempt na moni wey we win two spins before, and na dat illusion dey make am comfortable. E don be our own moni from di moment wey di dealer pay am.

For player wey like to follow sequence, e no get harm. But e no be method.
Questions wey pipo dey ask
1-2-4-8 na di Paroli to four wins; e dey risk di whole pile for every step. Di 1-3-2-6 dey keep 2 units afta step two, so if you lose for step three, e no cost anytin from your own pocket. Na di same expectation.
E go down small, with one or two spikes. About two sessions out of five dey end for profit afta 60 spins with dis unit.
Some players dey continue 1-3-2-6-12. Di next step dey win 2.7% of di time (five reds one afta di oda) and di shape na di same.
Small laugh
Four wins one afta di oda: 5.6%. Di sequence only dey decide how e go feel.
