Five reels, three rows, 20 lines — and every line pays in both directions. Three or more matching symbols from reel one or from reel five count as a win. A full line of five pays both directions at once.
When the same line pays left-to-right and right-to-left on one spin — two symbols bridged by a wild, or five-of-a-kind — the twin blades cross. Both wins are doubled.
Three torii gates award 12 free spins under the blood moon, where katana wilds fall on every reel. Each cross-cut climbs the Blade multiplier: ×1 → ×2 → ×3 → ×5 → ×8 → ×12 → ×20 — applied to every win, and it never resets inside the feature. Three more gates add 5 spins.
Enter the Blood Moon instantly for 71.6× your bet, priced from the measured value of the feature rather than rounded to a marketing number.
