How to play.
Appendix A · five rules
The basics
01
Place a peg.
Tap any empty hole that isn't on your opponent's edge row. Red owns the top and bottom edges; Black owns the left and right. You can never place on the opponent's two edges — those rows belong to them.
Knight's move
02
Build bridges.
Two pegs of your color form a bridge if they sit at opposite corners of a 2×3 rectangle — exactly a knight's move apart. Bridges connect automatically when you place. Tap one of your own bridges to remove it (sometimes you want the cross-route open instead).
No tangles
03
Don't cross.
A new bridge can't cross any existing bridge — yours or your opponent's. This is the heart of the game's tension: a single bridge denies a whole grid of would-be enemy bridges. Place where you both extend yourself and block them.
Win condition
04
Span your edges.
First player to form an unbroken chain of bridged pegs from one of their edge rows to the other wins. Pegs can be placed without bridges — the chain just needs to connect at the moment of placement, and once connected, stays connected (unless one of your own bridges gets removed).
Balance
05
Pie rule.
After Red's first move, Black may swap sides once instead of moving — taking over Red's position and Red's color. It balances the first-move advantage: Red is incentivised to play a first move that's strong but not too strong, since Black can steal it.
