A math expression becomes a machine: each operation is a piece, the numbers enter as dots along the lines, and the result falls into the bowl. The machine is assembled, taken apart, and runs to calculate.

Five modes and a workshop: repair the machine, build the number, guess the machine, order the pieces and simplify the machine; in the free workshop you assemble any machine you like. The app generates the machines, endlessly, from arithmetic to trigonometry, exponentials and logarithms. And every day, a machine of the day and a challenge of the day.

The first stage of each mode is free, and so are the workshop, the machine of the day and the challenge of the day. One purchase, the full game, opens the rest, endlessly. No accounts, no ads, no data collection; it works offline.
