In short: rows control how wide the probability curve becomes; risk level controls how aggressively multipliers are shifted from the centre out to the edges.
Adjusting the number of rows, typically between 8 and 16, reshapes the game's probability pyramid. It changes both the total number of landing slots and the spread of multiplier coefficients. Select a lower row count, say 8 rows, and the variance narrows: lower maximum payout caps, more predictable landing distributions. Expand the board to 16 rows and you add bounce decisions, which flattens the central bell curve and stretches the theoretical maximum multipliers on the far edges.
Risk levels, usually labelled Low, Medium (or Normal) and High, reallocate how multipliers are assigned across those available slots. Under a Low risk setting, central slots usually return a substantial portion of the stake, roughly 0.5x to 0.9x, while edge multipliers stay modest at about 5x to 16x. Under a High risk setting, central multipliers drop sharply, often to 0.2x, and the board compensates by lifting edge payouts up to 1,000x or higher.
Updated evidence on volatility and harm. Choosing high-risk configurations sharply increases session volatility, which can accelerate bankroll depletion during extended dry runs. That is not just a design observation. Population research links high-volatility, large-jackpot products to disproportionate harm:
