The Cheshire Cat Slot by Light & Wonder

Before any free spin plays out, the Cheshire Wheel makes one decision that sets the variance of the whole round. A single click of the wheel bonus picks two things at once: how many parallel reel arrays you'll run (up to 4 sets spinning side by side on every spin) and how many fully wild reels are locked in for the duration (up to 4, where every position on that reel pays as a Cheshire Cat logo). Land on a low slice and you get one array with no wild reels, which plays flat. Land on the 4-arrays-4-wild-reels slice and the bonus turns into a screen-filling cascade of overlapping wild reels firing across four boards at the same time. It is the rare bonus where the first action you take, before a single reel ever drops, is the action that matters most.

The base game has its own variance driver and it fires every single spin. The Mystery Symbol mechanic picks one random pay symbol at the start of each spin (Wild and Bonus are excluded) and then injects copies of it across the strips: 23 insertions on reels 1, 2 and 3, and 30 insertions on reels 4 and 5. The heavier loading on the right side is what produces the legacy land-cabinet's signature look: a wall of Alice silhouettes stacked across half the grid, or a corner-to-corner spread of cake slices, or a moonlit board full of Mad Hatter hats. The same selector runs on every free spin too, layered on top of whatever wild-reel and parallel-array setup the wheel handed you.

Trigger the bonus with 3, 4, or 5 cat-eye scatters anywhere on the reels and you get 5, 10, or 20 free spins respectively, plus a 10x or 50x total-bet scatter pay on the 4 and 5 hits. The Bonus symbol does not appear once free spins start, so there are no retriggers, but any round that finishes below 10x your total bet gets topped up to 10x at the end (the trigger pay counts toward that floor). Visually the game is pure Tim Burton-era Wonderland: a navy-blue night sky with a luminous full moon hanging behind silver tree trunks, a glowing orange-red masthead stretched above the reels, and a translucent blue gem border holding the 5x4 grid against a soft green forest. The Cheshire Cat's grin is the only bright thing on screen, and that is the whole point.
