No. IGT's Da Vinci Diamonds does not offer a bonus buy feature. The free-spins round can only be reached by landing three bonus symbols on reels 1, 2, and 3 during regular play.
- No purchase option at any bet size or price point
- Free spins are the only route into the bonus feature
- No source, review, or paytable lists an alternate bonus-buy RTP
Why Da Vinci Diamonds skips the bonus buy model
Da Vinci Diamonds dates back to 2007, well before bonus buy mechanics became a standard feature on newer video slots. IGT built the game around a trigger-based free spins round rather than a paid entry point, and that structure has never been retrofitted with a purchase option in any release reviewed across the sources checked for this page.
The trigger itself is specific: three bonus symbols must land on reels 1, 2, and 3, and the win has to register on a valid payline rather than simply appearing anywhere on the grid. That requirement makes the round harder to reach than a pure scatter-triggered bonus, which is one reason operators haven't layered a bonus buy price on top of it — the underlying trigger mechanic isn't built for a flat-fee shortcut.
Once triggered, the feature opens with 6 free spins, and retriggers can extend a session substantially — reports describe totals climbing as high as 300 free spins when bonus symbols keep landing during the round. Retrigger amounts vary by how many bonus symbols appear: two to four extra spins for three symbols, four to ten for four symbols, and six to fifteen for five symbols.
Some newer entries in the Da Vinci Diamonds family, including Da Vinci Diamonds Dual Play and MegaJackpots Da Vinci Diamonds, carry different math models and are sometimes confused with the original in listings. Neither variant is documented as offering a bonus buy either, based on the sources reviewed here.
Players who specifically want a purchasable bonus round won't find it in this title. The game rewards patience with the base reels and treats the free spins feature as an occasional payoff rather than an on-demand purchase.
Volatility without a bonus buy shortcut
Sources describe Da Vinci Diamonds as medium to medium-high volatility. Without a bonus buy, players can't pay to skip toward the free spins round — the tumbling reels and paylines have to do the work of building sessions on their own, so bankroll planning should assume the bonus round is an occasional event rather than an on-demand feature.

RTP with no bonus-buy adjustment
94.94%
Reported RTP for Da Vinci Diamonds sits in the 94.93-94.94% range. Because there's no bonus buy feature, there's no separate purchased-entry RTP to compare against the base figure — the number shown applies to standard play only.
How this compares to bonus-buy-enabled slots
Offers a fixed price to enter free spins directly, skipping the base-game trigger
No purchase option; free spins only reached through three bonus symbols on reels 1-3
Adds a second reel set but is not documented as offering a bonus buy either
Jackpot-linked variant with a different math model; no bonus buy reported
Trade-offs of a trigger-only bonus round
- Free spins feel earned rather than paid for, keeping the classic slot format intact
- No bonus buy means no way to reach the free spins round on demand
- Retrigger system can push total free spins far beyond the base 6-spin award
- The three-symbol trigger on reels 1-3 makes the bonus round appear relatively rarely
- Demo versions let players test the trigger frequency before wagering real money
- No alternate high-volatility bonus-buy configuration exists for players who prefer that format
Bonus buy questions about Da Vinci Diamonds
Does Da Vinci Diamonds have a bonus buy button at any casino?
No. The feature isn't built into the game's paytable or math model, so no licensed operator offers a purchase option for it.
Why doesn't a 2007 slot like this have a bonus buy?
Bonus buy mechanics became common well after this game's release, and IGT hasn't retrofitted the title with one in any version reviewed.
Does the demo version change the free spins trigger?
No. Demo play uses the same three-bonus-symbol trigger on reels 1-3 as real-money play, since there's no separate bonus-buy math to alter.
Can retriggers substitute for a bonus buy in terms of total spins?
They can extend a session substantially, with totals reported as high as 300 free spins, but they still depend on landing bonus symbols naturally rather than being purchased.
Do the Dual Play or MegaJackpots versions add a bonus buy instead?
Neither variant is documented with a bonus buy feature based on the sources checked; both keep the same trigger-based free spins format.
Is the free spins trigger frequency the same across all bet sizes?
The three-symbol trigger requirement doesn't change with stake size; hit frequency data for the bonus round specifically wasn't available in verified sources.
