📦 Box Split
🎯Goal: Split the whole grid into boxes (rectangles or
squares). Every box holds exactly one number, and that number is how
many squares the box covers.
👆How to play: Drag from one corner of a box to the opposite
corner. Tap a box to take it away. Tap a number to see its factor
pairs — 12 can be 1 × 12, 2 × 6 or 3 × 4 — and the boxes that still
fit.
⌨️Keyboard: Tab to the grid and move with the arrow keys.
Press Enter on one corner, stretch the box with the arrow keys, then
press Enter again to place it (Escape cancels). Delete takes away
the box under the cursor, and Ctrl+Z undoes.
🏆Win: Every square is in a box and every number has its own
box. Each puzzle has exactly one answer, and you can always reason
your way to it — no guessing! Solve it without hints for three
stars.
