Olav Games

Sources & method

Crosslight is our own game. Its rules and board construction are documented here.

The articles explain the implementation; they do not claim an external certification.

1. The rules of Crosslight ↗

   Our own game rules, controls and board definitions.

2. Why the puzzles are solvable ↗

   Our construction method. Each board is produced by legal moves from a blank board, so repeating those moves reverses it.
