Shuzan is calculation on the soroban. Equations fall from the top of the board and must be answered before they land.
Watch the math circles fall from the top. Tap an answer from the buttons below to resolve the matching circle. On easy mode one circle falls at a time; medium shows two simultaneously; hard launches four in staggered waves.
Resolve as many falling equations as possible without missing more than four.
