Locked Hearts 10 Slot by Fazi

Land a heart Wild during the free spins and it doesn't leave. That's the hook on this one. In the base game the red gem Wild behaves normally enough: it only shows up on reels 2, 3 and 4, and when it does it stretches to fill the full reel, turning every position there Wild and standing in for everything but the golden padlock Bonus symbol. Useful, but it vanishes on the next spin. Inside the bonus round the same Wild becomes a Locked Expanding Wild. It expands the reel as before, then sticks there for the rest of the round. So a session that opens with one full Wild reel can end with reels 2, 3 and 4 all permanently Wild, and any payline crossing them is paying every spin.

Three or more of the rose-wrapped padlocks trigger the round, and the count sets the length: three pays 10 spins, four pays 15, five pays 20. With more starting spins you get more chances for those Wilds to lock, which is where the Valentine's dressing hides a genuinely high-variance engine. The padlock never gets covered by a Wild, so retriggers stay live throughout. There's a Buy Bonus button if you'd rather skip straight to it.

Everything else is traditional fruit-machine furniture. Cherries, plums, lemons, oranges, sliced watermelons, purple grapes and golden bells spin on a gold-bordered grid against a deep crimson backdrop flecked with glossy hearts. The faceted red 7 sits at the top of the table and is the only symbol that pays from just two in a row, worth 200x for a full line of five. Three mystery jackpots, Gold, Diamond and Platinum, tick away across the header and can drop on any base spin, with bigger bets improving the odds. Any win can also be sent to a red-or-black gamble, doubling until you miss or hit the 50,000 ceiling.
