Starburst Slot Review — RTP, Volatility & How to Play

The entire mechanic of Book of Dead comes down to one moment: which symbol the RNG selects before your free spin round begins. That single variable — assigned before the first of your 10 free spins, outside your control — determines the ceiling for the entire round. Rich Wilde covering five reels on the right spin pays 5,000× your bet. A low-value card-rank symbol expanding on an identical board pays a fraction. At 96.21% RTP with genuine 5,000× potential and no bonus buy requirement, this is one of the more straightforward high-volatility slots at Yukon Casino — provided you understand the expanding symbol mechanic before sitting down.

What does the expanding symbol actually do?

Three or more Book scatter symbols anywhere on the reels trigger 10 free spins. Before the round begins, one symbol is randomly selected as the expanding symbol for the entire session. Whenever that symbol appears anywhere on the reels during free spins, it expands immediately to fill all three positions on that reel. Multiple expanding symbols on adjacent reels pay simultaneously across all active paylines. If the expanding symbol fills all five reels on a spin with all 10 paylines active, the payout reaches the 5,000× maximum. No bonus buy feature is required — the round triggers organically from scatter landings, and the 5,000× ceiling is accessible at any stake.

The symbol selection creates a second layer of variance within the feature itself. Landing three Books is the first RNG event. Getting a high-value symbol selected is the second. Sessions where Rich Wilde or the Book itself is chosen as the expanding symbol have a ceiling of 5,000×. Sessions where a card-rank symbol (10, J, Q, K, A) is selected are capped at a fraction of that. There is no mechanic to influence or improve the selection — the RNG assigns it independently of prior results, bet size, or session history.

Author's tip from Preston Hale, Casino Platform Reviewer: "Run the demo at Yukon Casino until you have seen at least three free spin rounds complete. Note which symbol gets selected each time — it tells you nothing about your real-money session since outcomes are fully independent, but it gives you a direct feel for how the expanding symbol mechanic plays and how wide the ceiling gap is between a Rich Wilde selection and a card-rank selection. I have had sessions where Rich Wilde came up on consecutive triggers and others where I saw it once in 10 rounds. That variance is the game."

Base game flow between free spin triggers

The Book symbol acts as wild and scatter simultaneously throughout the game. As a wild, it completes any payline by substituting for all other symbols. As a scatter, it contributes to the free spin trigger from any position across the five reels. Base-game wins are modest and infrequent — this is a high-volatility slot designed to concentrate its return in the free spin round. Sessions typically run 50–100 spins between feature triggers. At the C$0.01 minimum to C$5 per spin range available at Yukon, budget your session to cover at least 100 spins before expecting a feature to fire.

Retrigger — what it adds and how often it happens

Three or more scatters during the free spin round retrigger 10 additional spins, with the same expanding symbol maintained throughout. The symbol does not change on retrigger. A retriggered round with Rich Wilde as the expanding symbol is the scenario behind Book of Dead’s largest documented session wins. The trigger probability during free spins is similar to the base game — roughly one in every 250–300 spins on average — meaning consecutive retriggering is uncommon but not negligible. At C$1 per spin, a retriggered round with a high-value expanding symbol can return C$500–C$5,000 depending on reel coverage per spin.

Is Book of Dead worth playing at Yukon Casino?

For players who want genuine 5,000× potential from a simple mechanic without a bonus buy feature, Book of Dead delivers. The 96.21% RTP is above the high-volatility average. The mechanic is fully transparent — everything visible on screen, no hidden progression systems. The limitation is equally transparent: the expanding symbol lottery caps the round before it starts on low-value selections. Players who find that frustrating may prefer Gates of Olympus or Sweet Bonanza, where multipliers accumulate through the round rather than being fixed at entry. Set a session budget before playing and use Yukon’s deposit limit tools — this slot rewards patience and planned budgets more than any tactical decision during the round. Remember: casino slots are entertainment; players in Canada must be 19+ (18+ in Alberta, Manitoba, and Quebec).
