Merlin's Millions Slot by Light & Wonder

Merlin is a stacked wild, but he only lands on the middle three reels. When he does, every position in his column can swap to a wild, and that's where the SuperBet wager changes everything. Each of the five SuperBet levels adds a fixed amount to your stake and lifts the multiplier applied to Merlin's substitution wins. Level one runs them at x2; level five takes them to x10. So the same green-robed wizard that pays nothing on his own can turn a modest line hit into the biggest payout on screen, depending on how much extra you've fed the side bet.

Two scatters do separate jobs. The glowing blue Orb shows up on reels two, three and four, and three of them hand you five free games. Inside that round Merlin steps beside the reels and starts turning landed symbols wild, sometimes flipping entire stacks at once, and the SuperBet multiplier you set stays active the whole time. Three Owl symbols, which appear on reels one, three and five, open a pick round instead. You keep choosing owls and banking the prizes shown until one reveals Collect, and that bonus can also trigger mid free-games.

The setting leans into storybook fantasy. The cavern behind the reels has a waterfall spilling into a turquoise pool, the card royals are painted with twisting serpentine flourishes, and the premium icons are spell books and purple potion bottles lit in green. It plays as a straightforward 50-line game until the SuperBet decision forces you to weigh cost against wild power, which is the one choice that really shapes a session. Players who like that kind of ante control will find a cleaner version of it in newer ante-bet slots, and the wizard theme sits next to plenty of other magic titles in the catalog.
