How to play the hexagon block puzzle
- Look at the hex board. Each level is a wooden board made of hexagon cells. Some boards are small parallelograms; later ones grow into larger hex shapes. Your tray holds polyhex pieces whose cells add up to every free hex.
- Drag a piece onto the board. Touch or click a piece and drag it over the board. With a finger, the piece floats just above your fingertip. A green outline shows a legal snap; red means it overlaps a filled cell or leaves the board.
- Turn and flip. Tap a selected piece (or press Turn) to rotate it 60°. Press Flip for its mirror image. On a keyboard, R turns and F flips. Hex pieces have up to twelve looks.
- Move or take back pieces. Drag a placed piece to a new spot, or drag it off the board to return it to the tray. Undo steps back one move and Reset clears the board.
- Fill every hex. The level is solved when every free cell is covered exactly once. Stuck? Hint places one piece where it fits in a real solution of your current board.
Hexagon cells vs hexominoes (don’t mix them up)
Search results for “hexagon block puzzle” and “hexomino puzzle” often collide, but they are different games. A hexomino is a shape made of six square cells on a square grid—like a tetromino with two extra squares. Our hexomino puzzle is that game: 35 free hexominoes packed onto rectangular wooden boards.
This page is a hexagon block puzzle: the board itself is built from hexagon cells, and each piece is a polyhex—several hexes joined along their edges. Think of a honeycomb tray and wooden honeycomb tiles. If you came here looking for six-square pieces, jump to the hexomino page; if you want a true hex-grid packing puzzle, you are in the right place.
We also keep square-grid packing nearby: try square packing (solid n×n blocks) or the broader polyomino puzzle guide, and the free packing puzzle hub for the classic 8×8 wooden board.
All 3 free trihexes and 7 free tetrahexes
A trihex is three hexes joined edge to edge; a tetrahex is four. Allowing rotations and reflections there are exactly 3 free trihexes and 7 free tetrahexes—the same counts mathematicians list for free polyhexes. Our generator enumerates them with axial coordinates and keeps one canonical copy of each mirror family.
I3 is the straight bar (3 looks), V3 is the bent angle (6 looks), A3 is the compact triangle (only 2 looks). The seven tetrahexes range from a long bar (T4) to branching and skewed shapes with up to twelve orientations.
Hexagon block puzzle strategy
- Start with pieces that have the fewest homes. The triangle trihex (A3) and the most symmetric tetrahexes lock into tight pockets early.
- Fill the edges and sharp corners of parallelogram boards first; a long bar loves a straight side.
- Count in threes and fours: any closed-off region must have a size you can make with 3x + 4y. A pocket of 1, 2 or 5 hexes with no matching piece left is already a dead end—Undo.
- On a hex grid, “turning” is 60°, not 90°. If a piece almost fits, try one more turn before flipping.
- Use Hint when you are stuck: it places one piece from a real solution of the current board, then you can study why that cell had to be covered that way.
- 7 of our 17 levels have exactly one solution—those reward careful placement over trial and error.
Why this free hexagon block puzzle runs in the browser
Casual “hex block” games are often match-3 apps with timers and lives. PuzzlePave’s hexagon block puzzle is a quiet packing game in the same wooden style as our tetromino, tromino and square-packing boards: no countdown, no account, no download. Levels are pre-checked so every board has at least one solution; progress stays in your browser’s local storage on this device.
Phone and iPad come first. Boards are sized so hexes stay thumb-friendly at a 390-pixel width; drag lifts the piece above your finger so you can see the snap outline. Desktop players get the same board with mouse drag plus R/F shortcuts. Ads, when shown, sit below the game—never as a full-screen interstitial over the board.
Want more shape puzzles after you clear the set? Pack six-square pieces in the hexomino puzzle, fill grids with solid squares in square packing, or open the packing puzzle hub for the mixed polyomino board. The polyomino puzzle guide maps how trominoes, tetrominoes, pentominoes and hexominoes fit together—square cells, not hex cells, and that distinction is exactly why this hexagon block page exists.
17 solvable levels
Warm-up boards start at four hexes (a single tetrahex cluster) and a three-cell bar, then grow through 3×2 and 3×3 parallelograms into 15–25 cell packs and a radius-2 hexagon board (19 cells). Larger levels mix trihexes and tetrahexes so the area always matches. Every level was filled by a random tiling search and then verified with our exact-cover counter; 7 levels have a unique solution.
