A Venetian dual-reel carnival with tumbling wins and merging free spins
Masques of San Marco runs on two separate 5-reel sets of 20 paylines each, joined into a single 40-payline base game. During free spins the dividing line vanishes, merging the two sets into one wide 20-line board.
Winning symbols burst away in a fireworks-style animation and new symbols cascade down to fill the gaps. Each collapse can trigger fresh winning combinations from a single spin.
Landing three bonus scatter symbols on either the top or bottom half of the reels awards six free spins. The collapsing reels keep working through the feature, so a single trigger can snowball into extra value.
The Wild symbol is clearly marked with the word "Wild" in yellow and substitutes for every regular symbol except the bonus scatter.
Thanks to the frequent cascades, Masques of San Marco leans toward smaller, steadier wins rather than rare huge hits, making for a smoother, longer-lasting session.
Coin values run from 1 up to 50 per bet, with total coins wagered reaching up to 2000. Adjust your stake to match your budget before spinning.
Each spin plays out across two 5-reel sets with 20 paylines apiece, combining into the game's full 40-payline base game.
When you land a winning combination, those symbols disappear and new ones fall into place, giving you a chance at consecutive wins from the same spin.
Land three bonus scatter symbols on the top or bottom half of the reels to unlock six free spins, during which the two reel sets merge into one wider board.
Masques of San Marco splits its action across two 5-reel, 20-payline sets that combine into a 40-payline base game, with symbols that collapse and cascade after every win to open up chances at consecutive payouts from a single spin; landing three bonus scatter symbols on the top or bottom half of the reels awards six free spins, and during that feature the dividing line between the two reel sets disappears entirely, merging them into one wide board with an extra 20 paylines while the collapsing-reel mechanic keeps working, giving a modest starting allocation of spins real potential to grow before it's done.
IGT built its name on Dual Play slots after the success of Vinci Diamonds Dual Play, and Masques of San Marco is its follow-up take on that formula. Instead of a single reel set, the game splits into two 5-reel, 20-payline halves that run side by side, adding up to a 40-payline base game framed by a moonlit Piazza San Marco backdrop, complete with baroque architecture and gondolas.
The carnival theme shows up in the symbols themselves: four distinct masked figures alongside Sun, Moon, and Star icons, plus a Wild that spells out its own name in yellow so it’s never in doubt. Wins don’t just pay and reset here — matched symbols burst away and new ones cascade into place, opening the door to extra wins from the same spin without needing a fresh bet.
The free spins round is where the format really shows its personality. Landing three bonus scatters on the top or bottom half of the reels hands you six free spins, and the wall between the two reel sets drops away entirely, merging them into one board with an extra 20 paylines. It’s a lower-volatility, cascade-driven ride best suited to players who enjoy frequent, modest wins over long stretches of play rather than chasing rare jackpots — run it instantly in any modern browser on desktop or mobile, no download or plugin required.
