Kingdoms Rise: Legion Uprising Slot by Playtech

The setting is a canyon that's basically hell: black volcanic rock split by rivers of orange lava, jagged peaks under a strangely cold blue sky, and a grey-skinned undead king in a crown and teal cloak standing guard over the reels. That king is the wild, a gold "W" shield that covers everything except the Free Games scatter and pays the most on the board, up to 3,000x the line bet for five (line bet, not total, so read it against a single line). He's also what the bonus is built around.

Three or more stone FREE GAMES tablets start the Mighty King's Free Games, and it runs on one wild that walks. The round opens with a single wild parked on the middle position of reel 4 and a x2 multiplier attached to every win. Each spin that wild slides one reel to the left, reel 4 to 3 to 2 to 1, and the multiplier climbs a step with it, x2, x3, x4 and up toward x6. So it builds in reverse: the multiplier sits lowest while the wild is out on the right, and it peaks exactly as the wild reaches the leftmost reels, where left-to-right lines begin. Catch a tall stack of wilds late, at the high multiplier, and that's where the game's biggest hits come from.

Getting there doesn't depend on the scatter alone. Tokens drop onto symbols during normal play and get collected, then spent in the shared Kingdoms Rise Shop to buy features, the King's Free Games among them, plus bonuses borrowed from other games in the franchise. There's no fixed-price buy button. It all runs on the token currency you build up.

Over the top of everything sit three Kingdoms Rise progressive jackpots, pooled across every game in the franchise and dropped at random on any spin, with the red MAP scroll beside the reels tracking that cross-game metagame. The rest of the cast fills in around the king: a lava-veined dragon, a green-hooded sorceress with glowing eyes, a bare skeleton, a spellbook and a rune stone, then orange, pink, blue and purple gem royals down at the low end.
