Book of Dead still works because the formula is simple: high volatility, expanding-symbol free spins, and very little distraction around the main feature.
Payline mechanics guide
A slot payline connects stated reel positions. The active rules decide which symbols qualify, the direction of the win, and whether the line set is fixed or adjustable.
Use this table to compare the facts that change how each slot feels: provider, RTP, volatility, max win, and the main reason to open the full review.

A payline is a stated path through reel positions. A payout requires the right symbols to land on that path under the game's rules. The path may be horizontal, diagonal, stepped, or another named pattern; the number beside the game only tells you how many paths are available.
The rule set still controls where a qualifying combination starts, how many matching symbols are needed, and whether wins run left to right, right to left, or both ways. UK Gambling Commission standards require game information to explain what counts as a winning outcome, so the live help and paytable are the final check for the version in front of you.
Fixed paylines stay active together. Starburst uses 10 fixed paths and pays qualifying combinations in both directions. Fruit Million Respin uses 100 win lines, while Fire Joker compresses the format into five lines on three reels.
Adjustable-line games let the player choose a smaller active set. Play'n GO's official Book of Dead guide describes 10 available paylines with selection from one to 10. Activating fewer paths does not turn the unused patterns into wins, so the selected state and total stake need to be read together in the live game.
A payline follows a named path. A ways-to-win game normally checks matching symbols across adjacent reels without asking them to sit on one drawn line. Reel of Ra uses a five-reel, three-row layout with 243 ways, which is the full set of one-position choices across those reels.
Megaways adds changing reel heights, so its available ways can change from spin to spin. Pragmatic Play lists up to 200,704 ways for Buffalo King Megaways. That larger number does not prove a higher RTP, steadier payouts, or a better chance of reaching the maximum win.
Cluster Pays checks connected groups instead of named reel paths. A cascade describes winning symbols being removed and replaced after a payout. A scatter follows its own count and position rules. Any of those mechanics can appear beside another win system, but they do not become paylines because they share the same grid.
Separate the ordinary win rule from special symbols and what happens after a win. That keeps a ten-line classic, a 243-way slot, a variable-reel Megaways game, and a connected-symbol grid from being compared as if the numbers meant the same thing.
More paylines or ways do not set RTP, volatility, hit frequency, or maximum win. They describe how the board recognises combinations, while those other values describe different parts of the game model.
Start with the win-formation rule, then compare RTP, volatility, feature shape, and maximum win. Open the named review for title-specific settings and the active game's information for the exact version in use.

Play'n GO
Book of Dead still works because the formula is simple: high volatility, expanding-symbol free spins, and very little distraction around the main feature.

NetEnt
Starburst remains one of the easiest slots to understand: low-volatility pacing, frequent small hits, and a wild-respin feature that keeps the game flowing.

Play'n GO
Fire Joker is a compact classic slot with a low-friction 3-reel layout, stacked-symbol respins, and a multiplier wheel that keeps the old-school format from feeling empty.

BGaming
Fruit Million Respin is a medium-low volatility 5x4 fruit slot with 100 paylines, sticky expanding Wild respins, summed multipliers, and a 3,000x ceiling.

BGaming
Reel of Ra is a medium-low volatility Egyptian slot with 243 ways and a coin-only free-spins round powered by a separate multiplier reel.

Pragmatic Play
Buffalo King Megaways is still one of Pragmatic's cleaner wilderness bonus chasers because the free-spin trigger values are clear and the wild multipliers do the real work without extra clutter.
It is a stated path through reel positions. A payout forms when the required symbols land on that path under the game's direction and symbol-count rules.
Not by themselves. The line count does not set RTP, volatility, hit frequency, or maximum win, and different games price and activate their lines differently.
No. Ways normally check matching symbols on adjacent reels without following named paths. A payline uses a specific pattern of reel positions.
