Big Sevens Jackpot Slot by BigPot Gaming

Despite "Jackpot" in the title, there's no progressive or fixed jackpot here. The name refers to the Big Seven symbol - a special icon that only shows up on the middle reel during free spins and multiplies all collected coin values by 7x for each one that lands. Stack two Big Sevens and that's x14. All three middle positions filled gives x21. Coins appear on every reel except the center, each carrying a random bet-based value, and they lock in place when they land. The round starts with 3 spins, but any new coin or Big Seven resets the counter back to 3 - so the bonus keeps going until three consecutive empty spins. All coin winnings get tallied and multiplied at the end in a single payout, nothing pays during the round itself. Buy bonus is available for anyone who'd rather skip the 3-scatter trigger.

Copper-hammered symbol tiles sit inside a grid bordered by ornate golden gears and scrollwork - the whole thing looks like a vintage slot machine rebuilt with brass clockwork. Card values (J, 10, A, K) are dark embossed lettering against oxidized metal backgrounds, while the high-pays - golden bell with a ruby setting, a four-petal clover, single and double BAR - catch light against shinier surfaces. The Wild is a purple-and-gold gemstone that's easy to spot among all the warm bronze tones. Seven paylines. Only left to right. With just one bonus mechanic and a stripped-down base game, Big Sevens Jackpot is closer to Mega Sevens in scope than anything with multiple feature layers - the entire bet is on whether those Big Seven multipliers stack high enough before the respin counter runs dry.
