About Overfold
Overfold is an original puzzle that treats a sheet of paper as the board itself. Coloured pips sit on a grid, each in a matching pair, and you clear the board by tapping a crease between two rows or columns to fold the smaller flap over the rest — reflecting its cells down onto the ones beneath. Where a pip lands on its matching colour, both seal and score, and stacking several seals into one fold chains a combo. But fold two different colours onto the same cell and it jams permanently, blocking that square for good — and since a jam can never be cleared, it ends the board unless you Unfold it. The thing that makes it bite is permanence: every fold shrinks the paper for the rest of the puzzle, and the board only ever gets smaller, so the order of your folds is the whole strategy. Three Unfolds per board are your only safety valve when a fold goes wrong, and they are not refunded. Each board is built by scrambling a solved layout with inverse folds, so it is always solvable within its par. Free on desktop or mobile in the browser, it saves your best and invites a cleaner solve each retry.
How to play
- The paper grid holds colored pips, each colour in a matching pair.
- Tap a crease between two rows or columns to fold the smaller flap over the rest.
- Where a pip lands on a matching pip, both seal and score; several seals in one fold combo.
- Different colours colliding jam a cell permanently — and a jam ends the board (Unfold to take it back). The board is solved only when every pair has sealed.
Strategy & tips
- Every fold shrinks the paper permanently, so plan the order — the board only gets smaller.
- Line up matching pips to land on each other, and try to seal several in a single fold.
- Avoid folding different colours onto each other; a jam can never be cleared, so it ends the board unless you Unfold it.
- Use Unfold sparingly to recover from a bad fold — you get only three per board.
- Every board is solvable within its par fold count; chase a cleaner solve each retry.
FAQ
How does folding work?
Tapping a crease folds the smaller flap over the rest, reflecting its cells onto the ones beneath so pips can meet, seal, or jam.
Is every board solvable?
Yes. Each board is generated by scrambling a solved layout with inverse folds, so there is always a way to seal every pip.
Can I undo a fold?
Yes, with Unfold (the button or the U key). It restores the board, fold count and score exactly, but you get only three per board and they are not refunded.
