Lock & Hit: Red Knight Slot by Playtech

The gold crown coins are what you're really chasing. Six of them landing anywhere on a single spin lock the feature into place: every coin freezes where it sits, the rest of the reels drop away, and a run of respins begins with only coins in play. Each new coin that lands locks too and resets the respin count. Every locked coin holds a cash prize, and some carry something heavier, one of the four jackpots glowing along the bars across the top.

Those four are fixed, not progressive, and a jackpot only lands when a coin carrying it settles during the Lock & Hit. Mini pays 20x total bet, Minor 50x, Major 200x, and Mega 500x. There's no bonus buy and no ante here, so six coins have to turn up on their own. And the Mega on its own is not the top of the game. The overall cap sits far higher, around 5,000x, which you only approach with a board crammed full of coins and jackpots banking together rather than through any single prize.

The Red Knight's crested great-helm is the wild, standing in for everything except the coins and the FREE GAMES shield scatter. Land enough of those golden shields and the free spins begin, where the helm stops behaving like an ordinary wild and expands to cover its whole reel, while extra coins seed more coin-lock chances from inside the round.

It's a sunlit take on the medieval crusade rather than a grim one. A stone castle crowns a green hill behind the grid, thatched cottages and rolling meadows spread out under a clear blue sky, and the knight himself rides a white charger in gold barding. The 5x3 board is a deep royal-blue harlequin pattern, and the picture symbols keep the regal streak going: a flame-haired crowned queen up top, the white warhorse, a jewel-stuffed treasure chest and a red-wine chalice, with icy-blue A-K-Q-J-10 royals underneath.
