Legend of Fortune Slot by Light & Wonder

Stone walls are the thing to watch in the base game. At any point on a normal spin, slabs grind inward and turn a whole reel wild, starting at reel 5, then pushing through reels 1, 4 and 2 one at a time. They keep crushing until a win lands, and on a good run all five reels can go wild at once. It's a random trigger, so there's no symbol to chase. You just watch the walls move. The gold totem Wild also shows up on its own and fills in for everything bar the scatter.

Around the reels sits a weathered green-stone temple wall with gold corner studs, the gold-and-jade logo arched over the top. Behind it runs a sunlit Central American jungle: palm fronds either side, a hazy blue mountain, a stepped Mayan pyramid off to the right, and a military-green jeep half-hidden in the leaves. A toucan, a red poison-dart frog, crossed wooden paddles on a red banner and a leather map journal pay above the green and copper royals.

The scatter only lands on reels 2, 3 and 4, so three of them is the trigger. That opens a Bonus Feature Selector with three passages, and you play only the one you pick. Temple Escape hands over 8 free spins where you inch along a map by collecting a Character on reel 5, setting off traps that work in your favour: wild darts, crushing spikes that turn full reels wild after a spin, and a Pit of Wealth that drops a random giant symbol into empty spots. The map can also tack on +2 spins. Cave-In gives 10 free spins where winning symbols blow up and the ones above tumble down, chaining until nothing new connects.

The third door is Stepping Stones, and it ignores the reels entirely. You pick a route across stones to collect rising multipliers, the current one overwritten each time you advance, and landing on a bonus stone can bring fallen stones back. Reach the final stone and a Bonus Wheel spins for a multiplier worth up to 1,000x the total bet. No jackpot, no way to buy in, and the wild reels from Light & Wonder arriving as full crushing walls are the closest thing to expanding wilds you get here.
