Row count decides how many slots exist and how far apart the extremes sit. It does not decide how much the game returns.
Each row is one left-or-right decision. Eight rows means eight decisions and nine possible landing slots; sixteen rows means sixteen decisions and seventeen slots. More decisions means the outcomes spread further and the extremes become rarer.
| Rows | Slots | Chance of the far edge |
|---|---|---|
| 8 | 9 | 1 in 256 |
| 12 | 13 | 1 in 4 096 |
| 16 | 17 | 1 in 65 536 |
Fewer rows produces a narrower, calmer distribution: the edges are reachable and the multipliers there are modest. More rows produces the opposite. Neither is better value — the payout tables are adjusted so that both land on the same return.
The practical question is how long you want a session to last for a given budget. Sixteen rows at high risk will resolve that question faster than eight at low.
