Chimney Sweep by Endorphina
Chimney Sweep is a classic 5x3 slot from Endorphina with 10 fixed lines, an autumn rooftop setting, and a simple but punchy pay model. From a math perspective, the core identity is clear, wilds double any qualifying line win, and the bonus round applies a fixed x3 multiplier to every free spin result.
The numbers tell you this is built as a compact traditional game rather than a feature-heavy modern slot. RTP is 96.07%, the stated volatility is high, and the ceiling is 9000x. I think the mechanical simplicity helps readability, but the base game can drag a bit if you want constant feature interaction.
Paytable & Paylines
5 reels and 3 rows are paired with 10 fixed paylines, so line placement matters more here than in ways games. Looking at the paytable structure, low symbols are A, K, Q, J, 10 and 9, mid symbols include the rooster weather vane, rainbow and horseshoe, while the bluebird and pig sit at the top of the regular set.
Chimney sweeper is the wild and also the highest-value symbol, with five wilds paying 900x the base bet according to the paytable panel. A fireplace is the scatter and pays up to 500x for five. Provider text also states that any winning line containing one or more wilds is doubled, which is the real value driver.

Game Features
3 or more scatter symbols on an active payline trigger 15 free spins. During the feature, every spin win is multiplied by x3, and free spins can re-trigger at the current stake. From a math perspective, that fixed multiplier is more meaningful than the feature count itself because it lifts every ordinary line hit inside the round.
Wild substitution is straightforward, it replaces all regular symbols but not scatter. The extra twist is the line-win doubling rule, which applies in the base game and free spins. Risk Game and Bonus Pop are also listed among the core features, although no exact cost or trigger model is given for them.

RTP, Volatility and Win Potential
96.07% RTP places Chimney Sweep in a standard return bracket, but volatility data is inconsistent across sources. I use the high-volatility value because it comes with the stronger technical detail set. That fits the model better as well, because a 9000x top payout and doubled wild lines create sharper payout concentration than a low-volatility label suggests.
Maximum win is quoted as 9000x in the review source, which aligns with the top-end positioning around five wilds and enhanced free-spin payouts. No hit frequency is supplied, so I cannot estimate exact feature cadence. Still, the maths look bonus-led rather than base-led, and not everyone will enjoy the waiting time between meaningful spikes.
