📜 The Rules (Epic Version)

1. Colour Groups (Colour +)

Each player uses a "Colour +" made up of neighbouring hues on the colour wheel:

• Blue +: Blue, Purple, Green.
• Yellow +: Yellow, Orange, Green.
• Red + (Destruction): Red, Purple, Orange.

2. Bridge Building & Scoring

• Bridge points: rows of 3 stones score 1 point (3-bridge), rows of 4 stones score 2 points (4-bridge).
• Region bonus: every bridge that is your first in a region (a board like S1, G4 …) gives 1 extra point — but only if the bridge completely covers an inner cell of that board (endpoints don't count because the line only half-covers them).
• Separate display: bridge and region points are shown separately — add them yourself at the end.
• Important: two identical colours may not lie directly next to each other.
• A bridge must be placed in the same turn as the stone that completes the row.
• A 3 can't be extended to a 4: once you've placed a 3-bridge, you can't later add a fourth stone to grow it into a 4. „Nothing but meanness in this game!" — Walter. If instead you only add the fourth stone to the row (without a 3-bridge), the option of a direct 4-bridge stays open — but then you risk the opponent cutting in between.
• How to place a bridge: double-click (or double-tap) the first stone of the row, then double-click the last stone. If the row is valid (3 or 4 stones, all in your colour group or all red, no two identical colours in a row), the bridge is drawn. A second double-click on the same stone clears the selection again.
• If you place on a dot (off-board cell), the bridge is drawn automatically — because off-board placements are only allowed when they close a bridge in the same turn anyway.

3. Red Bridges & Cutting ("Cut")

• Red bridges are used for defence.
• When a red bridge crosses a blue/yellow one, the latter loses its value.
• Geometry: bridges can only be cut at their inner cells; the endpoints are immune.
• Diagonals can cross between endpoint and inner cell.
• Cut bridges stay on the board: a cut bridge is drawn grey and dashed — it loses both its bridge and its region points, but stays physically in play and still blocks anything you'd want to build across it (whether scoring or red).

4. Off-board Cells & Boards

• Dots (•): the small dots mark cells outside the boards. Stones may only be placed on such dot cells if they complete a bridge in the same turn.
• Only one stone of a row may lie off-board.
• Andres Kuusk (world champion of abstract games) calls this rule „an excellent rule":-)

5. Three Sets (Stock)

• Each player doesn't get all 36 stones at once, but in three sets of 12.
• Blue: 4 Blue, 3 Purple, 2 Green, 2 Red, 1 Orange — per set.
• Yellow: 4 Yellow, 3 Orange, 2 Green, 2 Red, 1 Purple — per set.
• As soon as a player has placed all 12 stones, they automatically receive the next set. Display shows „Set 1/3 → 2/3 → 3/3 (last)" on the player's turn.
• End-game tip: the transitions at move 12 and move 24 noticeably shift tactics — what's still in stock after the last set often decides the game.

6. Undo & Save

• ↶ Undo move: each click on this button undoes one action — stone back into inventory, bridge removed, player's turn restored. Press it as many times as you like, all the way back to the start of the game.
• Auto-save: the current game is automatically saved in the browser. When you close the page and reopen it later, „▶ Resume last game" appears at the top of the start menu.
• 💾 Save / 📂 Load: download the game state as a JSON file or load a previously saved file.
• Share on WhatsApp (top): sends a link to the current position. With the option „Include position as CSV", the starting position is also attached as a CSV file so the recipient can load the same position.
