Flip pistachio shells into binary and match the sack's number
Every row of pistachios in Pistacho Flip is a binary number. An open shell counts as 1 and a closed shell counts as 0. Tap the shells to open or close them until the row's total matches the number written on the burlap sack, and do it before the timer runs out.
The first rows are short, only three shells long, so you can see how each shell changes the total. As you move through the 15 levels, the rows grow until they're seven shells long, and every tap matters more. A single shell at the far end of the row can flip the total from much too low to much too high.
After that, one row isn't enough. Two rows of pistachios show up together, and you have to add them up to hit the sack's target. Now you're deciding which row should carry the big values and which one fills in the rest, all with the clock still running.
In later levels, going over the target costs you. Each overshoot takes penalty seconds off your timer, so random tapping stops working. Read the sack, work out the bits, and open just the shells you need.
Pistacho Flip is a short, focused puzzle game built on one idea: shells, binary numbers, a target, and a timer. Crack the number on the sack and move on to the next level.
