Da Vinci Diamonds Dual Play is the 40-payline expansion of the classic da vinci diamonds igt slots title, built by High 5 Games and published under IGT. It doubles the original payline count, widens the bet range to $0.40–$400 per spin, and layers in an optional progressive jackpot side bet — changes that meaningfully shift the math compared to the base game.

How Does Dual Play Differ from the Original Da Vinci Diamonds Slot Machine?

The Da Vinci Diamonds slot machine runs 20 fixed paylines on a 5×3 grid. Dual Play expands to 40 fixed paylines. More paylines mean more ways to land symbol combinations on every spin, though total bet size rises with them since all paylines are always active.

  • Paylines: 20 (original) vs. 40 (Dual Play)
  • Bet range: $0.20–$100 (FanDuel original) vs. $0.40–$400 (DraftKings Dual Play)
  • Progressive jackpots: None in the original; Mini, Minor, Major, and Mega available in Dual Play
  • Progressive side bet cost: $0.25 per spin, optional

The original game carries a 5,000x-stake maximum payout and no jackpot. Dual Play keeps that fixed-cap structure on the base game but adds the four-tier progressive ladder when the side bet is active.

What Does the $0.25 Progressive Side Bet Actually Cost?

At DraftKings Casino — where Dual Play is live in CT, MI, NJ, PA, and WV — the side bet is exactly $0.25 per spin on top of the base wager. It is optional and can be toggled off. When active, it unlocks access to the Mini, Minor, Major, and Mega jackpot tiers.

Important math: the side bet increases the effective house edge on that $0.25 portion of every wager. Players who run the side bet continuously across a long session will feel that drag on their bankroll, separate from the base game's ~5.06% house edge.

Where Can You Play Da Vinci Diamonds Dual Play for Real Money?

DraftKings Casino is the primary confirmed US operator for the Dual Play variant, available in Connecticut, Michigan, New Jersey, Pennsylvania, and West Virginia. For the standard 20-payline version at other operators, see the full guide to play da vinci diamonds at licensed US casinos.

How Do the Free Spins Work in Dual Play?

Dual Play triggers up to 6 free spins per bonus activation — fewer per trigger than the free spin da vinci diamonds bonus in the original, which can award up to 300 spins through retriggering. The Tumbling Reels mechanic carries over: winning symbols clear and replacements fall from above, potentially chaining multiple wins on a single free spin. For a full breakdown of how that cascade mechanic works, see the guide on how tumbling reels work in Da Vinci Diamonds.

Is Dual Play Worth Choosing Over the Original?

It depends on goals. The wider bet range ($0.40–$400) suits higher-stakes players. The 40 paylines give more frequent base-game hits. But the optional side bet adds cost, and the published RTP for the series hovers around 94.94% — already on the lower end versus some modern slots.
