Mega Sevens Slot by BigPot Gaming

Seven scatters to trigger free spins. Not three, not five - seven. On a 20-position grid, that's 35% of all symbol spots filled with pink crystal scatters before anything happens, which means most of your time in the base game is waiting. For 105x your bet, the buy option skips the hunt entirely and drops you straight into the bonus round.

And the bonus round is where the game's one real idea lives. Every position where a scatter landed during the trigger gets a bronze frame. During free spins, any scatter that hits a framed position upgrades that frame - bronze to silver, silver to gold. Bronze frames pay between x1 and x7 on the final spin, silver frames jump to x9 through x77, and gold frames reach x100 to x777. The frames only resolve on the last free spin, so the entire round is about upgrading as many positions as possible before time runs out. Landing 3+ scatters during the round adds more spins (equal to the scatter count), which gives more chances to push frames higher. The interaction is straightforward but creates genuine tension - you're watching specific grid positions and hoping scatters land on frames rather than empty spots.

Dark bronze metalwork and clockwork gears border the reels, with arched cathedral windows and stone pillars glowing in warm amber light behind everything. Iron card symbols sit heavy against teal backgrounds, and the premium symbols lean full steampunk - a golden armored knight, an ornate treasure chest, and the "7" rendered with visible gear mechanisms welded into the metal. The whole palette is bronze, gold, and deep teal, broken only by those pink crystal scatters catching light across the grid.
