How to play Hex Puzzle
The piece count always adds up exactly
The total number of cells across all the pieces equals the number of cells on the board. Nothing is left over and nothing is missing, so finishing is a matter of arrangement, not of luck.
Pieces go in whole or not at all
A piece is rejected if any part of it would fall outside the board or land on a cell that is already covered. Pieces cannot be squashed to fit around an obstruction.
Which is why a jam means you went wrong earlier
Since the totals match exactly, the only way to run out of room is to have put an earlier piece in the wrong place. Tap a placed piece to lift it back out and try again — there is no penalty for it.
Every board can be filled
The board is made by taking a complete patch of hexagons, cutting it into pieces, and then shuffling those pieces. Cutting and assembling are opposite operations, so putting each piece back the way it came always works. You are never handed a board that cannot be finished.
Rotate before you place
A piece can be turned in sixty-degree steps. The thumbnail in the tray updates as you turn it, so you can see the shape you are about to put down.
Six turns bring a piece back
Hexagons have six-fold symmetry, so a piece that has been turned six times is exactly where it started. Nothing can be rotated into a state it cannot be rotated out of.
Hex Puzzle Tips and Strategy
Fill the awkward cells first
Cells sticking out along the border can only be reached by pieces with a matching protruding cell, and they get harder to cover once the middle is filled. Start at the edge of the patch and work inward. Interior pieces are easy to shift later, but a wrong one at the edge can strand three pieces at once.
Read the holes, not the outlines
A gap tells you what shape has to fill it: a single empty cell needs a piece with one cell there, and an angled gap needs a matching edge. Work outward from the gaps, because empty space is a much stronger clue than a piece's outline. Most jams trace back to a gap that was easy to fill early on.
Place the odd piece first
The piece with a single protruding cell, or a notch that nothing else matches, is the hardest one to tuck in later. Put those down while there is still open board around them. Ordinary rectangles are the easiest to place and the easiest to work around, so leaving them until the end costs you nothing.
Hex Puzzle — Frequently Asked Questions
I have one piece left and it does not fit. What went wrong?
An earlier piece is in the wrong place. The pieces and the board have exactly the same number of cells, so a genuinely fitting arrangement always exists — lift a piece out by tapping it and try another spot.
Can I make a board impossible to finish?
No. The board is produced by cutting up a complete patch, so the original arrangement is always a valid solution.
How do I lift a piece back out?
Tap it on the board. It returns to the tray with no penalty.
Does it need installing or an account?
No. It runs in the browser on a phone, tablet or computer and works offline after the first visit.
