The story
Fiction and adapted settings written by Akitsora Gaming for this title, including invented dialogue and events. This is not a historical or folklore reference. The rules and specification tables define the gameplay and math.
Early morning in the dojo, the cypress floorboards freshly wiped clean.
Five tall stacks of grey roof tiles wait as the master draws a single breath.
I. Tameshiwari in the Quiet Dojo
At daybreak the sliding doors of the karate hall stand open to the cool morning air, yet inside the room not a student stirs. Kneeling in straight rows along the wall in white training gi, they watch the centre of the floor where five wooden blocks hold tall stacks of heavy clay roof tiles prepared for tameshiwari—the test of breaking.
Thin wooden spacers separate tile from tile across the five stacks so the force of a blow travels cleanly downward. There are no spinning reels or paylines here; instead, the master steps bare-footed before the stands, centres his breathing, and focuses all his strength into his striking hand.
II. Only the Broken Tiles Count
With a sharp shout, the master drives his fist downward and shatters the top tiles of a chosen stack. The rule of the dojo is simple: only the broken tiles count. If enough matching symbols appear among the shattered pieces, the punch scores a win, aided by wild kiai symbols that count toward every kind of tile at once.
Every winning strike earns an immediate follow-up chain punch within the same spin. As the broken fragments clear and fresh tiles settle onto the top of the stack, the second punch doubles its payout, the third triples it, and the combo continues as long as the punches keep connecting.
III. Grading Through the Belts
When a spin finishes with enough golden rank badges visible on the stacks, the red-and-white dojo banners unfurl for the grading free spins. Starting at white belt, every single roof tile the master shatters is tallied one by one on a cumulative counter throughout the bonus.
Crossing each tile threshold promotes the master to the next rank—from white belt to brown belt, and from brown to black belt. Each promotion awards an extra spin, raises the belt multiplier, and drives every punch deeper into the stack so more tiles shatter at a time.
IV. The Red-and-White Belt Five-Stack Break
At the summit of the grading ladder awaits the grandmaster's red-and-white belt. Once enough tiles have been broken across the round to tie that ceremonial belt around his waist, the master opens every remaining spin with the ultimate technique: the five-stack break.
On that opening strike, all five stacks of roof tiles shatter from top to bottom at the same instant, evaluating each stack separately under the top belt multiplier before any follow-up chain punches begin. It is the game's theme, not a promise: tile breaking and belt promotions belong to martial arts tradition, while every punch is still decided by the RGS random number generator.
