Definition
Two tiles on the board are called adjacent they share an edge.

A player wins there is a sequence of tiles $\sequence {h_i}_{1 \mathop \le i \mathop \le n}$ such that:
 * Every $h_i$ is marked with that player's symbol
 * $h_i$ is adjacent to $h_{i + 1}$ for every $1 \le i < n$
 * $h_1$ is on one of the player's sides, and $h_n$ is on the other
