The whole game pivots on one character. Roger is a small spiky hedgehog who shows up after every spin, then rolls across the 5×3 grid between 3 and 15 cells before tumbling off the bottom edge. He never touches the same tile twice on the same spin. Every cell he crosses can either pay as it stands or get converted into a Letter Wild, and that conversion takes 5 acorns out of your collected pile. Watching where he rolls is honestly the only thing to do between spins.
Acorns are the currency that holds the whole feature set together. There is a counter capped at 120 acorns sitting near the reels, and that meter funds three different things. Wild conversions cost 5 acorns each. The Autumn Feature, the named bonus baked into the game, triggers at 40 acorns. And once you reach the Free Spins round through 3 or more Scatters, each free spin you play burns 1 acorn from the same stash. So the bonus round literally ends when Roger runs out of food, which is a strange way of running a free spins feature compared to the fixed-count rounds most studios ship.
The maths runs pay-anywhere on the 5×3, so wins evaluate by counting matching symbols across reels regardless of where they sit. That fits the rolling mechanic well, since Roger's trail can leave Wilds in disconnected pockets and still glue paydays together. Volatility lands in the medium tier, RTP is the 96.61% headline (some review sites cite a higher 98.09% variant for licensed jurisdictions), and the bet range runs from 0.25 up to 2,500 a spin.
The art is a cosy autumn woodland scene. Red and orange foliage in the back, golden leaves drifting through the frame, oak trees behind the reels, soft sunset light. Symbols include acorns, pine cones, oak leaves, butterflies, and a red-spotted mushroom alongside the card royals in a carved-wood style. The wordmark is bold orange and green serif with a leaf ornament. One small gripe, there is no real ceiling number anywhere in the demo UI, which makes the Autumn Feature feel like a wildcard rather than a known target.
No Buy Feature, no Super Bet, no ante. There is a standard Gamble button after each win that double-or-nothings your last payout on a card flip. Everything else lives or dies on how generous Roger feels about your acorn stash.
