Solution, FAQ and sources

Solution

Each break splits one piece into two, so every break increases the number of pieces by exactly one — however you do it.

You start with 1 piece and need 30, so you need 30 − 1 = **29** breaks. There's no shortcut, and no way to do worse either, as long as you follow the no-stacking rule.

A chocolate bar is a 5 × 6 grid of 30 squares. You can only break along the grooves, one piece at a time, and you can’t stack pieces to break them together. What’s the fewest number of breaks needed to separate all 30 squares?
