STILLBLADE
A lone ronin waits at the mountain crossing. Two blades cut a path through the reels, turning every struck cell Wild. Wins tumble, scars deepen, and The Long Night keeps the marks alive.
One Cut. Every Scar Remains.
Stillblade: Crosscut is a 5×4 tumble slot with fourteen fixed paylines. Three or more matching symbols pay from the left, and scars on those cells add into one multiplier. The current game targets 96.40% RTP on an ordinary spin and caps the entire paid round, including The Long Night, at 4,500× the stake.
Fourteen Lines, Five Reels
Set the stake and spin. Each of the fourteen lines pays its best combination from the first reel. Winning symbols clear, the survivors fall in order, and new symbols enter from above. Every tumble belongs to the same spin.
The Path Becomes Wild
Two Crosscuts strike the straight path between their cells. Four blades form two cuts, crossing where possible. Each struck cell becomes Wild and gains a 2× scar, or doubles its existing scar up to 32×. A lone blade becomes Wild without creating a scar.
The Board Remembers
Winning cells also earn or double their scars after paying. Three, four or five Gates open 8, 10 or 12 free spins. The triggering scars carry in, the first and last free spins guarantee a blade pair, and the marks stay until the night ends.
Share of 500,000 ordinary paid rounds reaching each multiplier, including naturally triggered free spins. Sampled from law 0.2.2; not a certified distribution.
Fourteen Lines At The Crossing
Five reels of four rows stand at the mountain pass with the ronin beside them. The eight paying symbols run from the Menpō Mask to the Mon Coin; SPIN states its cost and BUY FEATURE sits beside the stake.
Two Blades Make One Straight Cut
Two Crosscuts land and the blade strikes the straight path between them. Every cell the stroke crosses turns Wild and takes a 2× mark, and the win plays out before anything falls.
Every Cut Leaves A Mark
The marked cells pay: this line is worth 12.00 CR, and the board carries 2× marks beside a 4× where a second stroke crossed the first. Scars on a winning line's matching cells add into one factor, 2× through 32×.
Three Gates Open Eight Free Spins
The entry card names what the Gates opened and waits for the press. Scars from the triggering draw carry into the feature, and Gates inside it retrigger the same award.
The Night Keeps Its Multipliers
Free spin six of the run. The crossing has turned to night and the board holds its marks at 2×, 4×, 8× and 16× while new wins deepen them. The feature's running total stands at 50.50 CR.
The Cards Come Up At Fifteen, Thirty, Sixty
The feature closes on its own total, 57.50 credits on a 1.00 stake. The four cards are BIG WIN at ×15, MEGA WIN at ×30, EPIC WIN at ×60 and EXPLOSIVE WIN at ×1,000, all under the 4,500× whole-round cap.
A Seed. A Receipt. A Replay.
The current playable build uses demo credits and a deterministic local engine. Its rules, receipts and simulation results are documented; a production outcome service and independent certification are not part of this demo.
SEED
Each spin derives its own seed. Replaying that seed under the same law reproduces the draw, cuts and tumble sequence.
RECEIPT
The engine records the initial board, stages, scars and credited win. Presentation plays those results without changing the award.
MEASURE
The current audit samples 20 million paid rounds. It measures 96.3163% against the 96.40% target; feature buys target 98.00%.
Documented rules and reproducible samples. Independent certification is pending.
