World of Wonka Slot by Light & Wonder

Light & Wonder paid for the full Warner Bros license here, and the 1971 Gene Wilder film does the heavy lifting. Willy Wonka, Charlie Bucket, Veruca Salt, Mike Teevee and Grandpa Joe all appear as premium symbols pulled straight from the Mel Stuart movie, and the soundtrack rotates through Taradam Music's "Golden Ticket," "Oompa Loompa" and "Pure Imagination." It's a separate title from the older "Willy Wonka Pure Imagination" release, so don't confuse the two when you see them sitting next to each other in a L&W lobby.

The base layout is six reels by four rows with 50 fixed lines, set against a cartoon countryside of rolling green hills, candy boulders and a distant chocolate factory silhouette. Symbol art keeps the painted-portrait style: each character sits inside an ornate gold-or-jewel frame, with sweets and gobstoppers filling the low pays. The Wonka Wheel intro hints at where the extras come from before a spin even resolves.

The mechanic that actually changes how the game plays is the Oompa Loompa Feature. On a triggering spin the grid expands outward, adding columns until you're looking at either an 8x4 or a full 10x4 array. Wins evaluate across the wider grid on that spin, so symbol clumps that would have died in the 6-wide base suddenly have room to line up. Free Spins push this idea further by running two parallel reel sets that get evaluated separately, meaning a single triggering scatter pattern can pay twice on the same spin from two independent calculations.

There's no buy bonus, which is unusual for a 2023 release at this price tier. You wait for the free spins trigger the old-fashioned way, and that's deliberate; with two parallel grids inside the bonus the math wouldn't survive being sold for 80x or 100x. The volatility sits in that medium-high range where the base game ticks over on character line hits while the real bursts come from grid expansions stacking the right premium.

If you grew up watching the Gene Wilder version on TV every Easter, the licensing alone is the draw. The game leans into it hard, treating the movie as the product rather than just the wrapper.
