Hints

Keywords	Hint
getting started	It is not necessary to fully play out any of the games. You only need to match each notation block to the right game, and identify the red symbol.
solving clues	The game notations are inspired by algebraic chess notation. Notation blocks 1, 3, 5, 6, 8, and 11 (counting from the top) use a rectangular grid system similar to chess, while the other notation blocks are for games that don't have a grid.
