Sushi Mat Roll

Drag the bamboo mat to roll a tight sushi cylinder, then swipe down with the knife to slice perfect pieces.

Core mechanic

Drag horizontally to roll the mat, compressing the fillings; once tight, swipe down to slice; thickness of roll determines score.

Controls

Drag sideways to roll the mat; swipe straight down to slice; one thumb throughout.

Theme

Minimalist sushi counter with bamboo mat, washi textures, soy-sauce brush strokes, and a serene chef background.

Why now

Food-prep content is constantly viral; an ASMR roll-and-slice loop captures sushi-night TikTok energy.
