Math Machine:
gears machine mathematics

The logical game, how to make the needed sum by putting the tile-value into different Math-Machines (Gears).
The tile with initial value is placed on a table 5x5 cells.
Four "Math-Machines" are present on the table. Each Math-Machine has its function: "x2"; "÷2"; "+2"; "-1". -
["x2" - multiply by 2; "÷2" - divide by 2; "+2" - add 2; "-1" - subtract 1]
When the tile gets into some Math-Machine, its value changes according to the Machine's Math function: (e.g. If the initial tile value was 4, and the Math-Machine function is "x2", after the Machine action the tile value will become 8 [4 x 2 = 8], etc...).
You may move the tile by the cells of the table (swipe over the tile left-right; up-down, or arrow-keys).
Try to pass through appropriate Math-Machines to receive the needed value (given at right).
When you get the needed sum, you may go to the next level.
To win the game, get to the top 7th level.
Controls: Swipe over the tile to push it left-right; up-down (or arrow-keys).
